When I was born in 1990 my grandparents spent like 5k on government bonds that my dad didn't tell me about until I was 30.

It was a very nice treat, but when I did the math to see how much more it would have been if just invested in the market I gasped.

ryandrake · 19h ago
Not comparing apples to apples, though. Those government bonds were, by any reasonable measurement, risk free (EDIT: as another commenter noted, not exactly, we could call them "minimal risk"), while "the market" is not.

Looking back in hindsight is always risk-free, though, which can lead to faulty conclusions.

jameslk · 19h ago
On the timescale of 30 years for gov bonds vs diversified US stocks, this is almost meaningless statement. The longer a risky asset is held, the less chance of loss you’ll have. Short-horizon returns are extremely volatile, but that volatility "mean-reverts" over time.

This is especially true for stocks vs bonds. Because the cash flows of bonds are fixed, prolonged inflation or rate spikes can deliver a loss that stays a loss, making long-term "safety" in bonds partly an illusion.

> The longer a risky asset is held, the less chance of loss you’ll have

I understand what you are trying to say here, but it really depends on what the “risky asset” is. If you hold a diversified set of risky assets, like a stock market index fund, then what you say is correct.

However, there are other risky assets that don’t hold to this “a long time horizon reduces risk” statement. For example, if you put all your investment in a single stock, that is a risky asset that does not necessarily revert to the mean over time. Many companies go out of business, and the stock goes to zero and will never recover no matter how long you wait.

It is important to note what kind of risk you are taking.

This is only true if you look back 30 years. What will happen in the next 30 years? Do you know for sure?

Realistically, all that actually matters is where I land relative to the population at large. Since so much of the world economy is tied to stocks, by buying into it I will remain at least at parity with my current socioeconomic status regardless of whether the market goes up or down. Nobody with real money is just holding it in cash in case the whole stock thing doesn't work out.

If things go the way they have been for a while now, I'll be able to retire comfortably. If stocks don't gain or lose a penny for the next 40 years, I think society as a whole will have reframed retirement. If society collapses, it didn't matter anyways.

Lerc · 17h ago
I guess the questions to be asked would be

Will the US economy completely collapse in the next 30 years?

Will the US government completely collapse in the next 30 years.

For the past century I think the answers to those questions would have been, "Almost certainly not" and "Not a chance in hell"

I honestly didn't know where they stand today, but there's definitely been movement.

The past century, you say... wasn't there a little thing called 'the great depression' somewhere around a century ago?

Wasn't a complete collapse. It took a significant hit, but still functioned.
jameslk · 18h ago
The same type of argument can be made about bonds and even cash.

And if a diversified portfolio of US stocks all suddenly go bankrupt, that probably means the US is toast and therefore bonds are screwed too.

Outside of catastrophic black swan events, like I said, stocks generally mean revert if you have a long enough time horizon to allow it

ty6853 · 18h ago
Holding stocks in the nation in which you live probably isn't very smart from a hedge perspective, considering US stocks don't have a locked correlation to foreign ones. Your assets would all be in the shitter at the same time you're out the job and need to liquidate them to survive.
jameslk · 18h ago
Yes I agree. I was using US stocks for the sake of comparison against US bonds. Otherwise, a diversified portfolio with risk adjusted to goals is what makes sense
southernplaces7 · 11h ago
>that probably means the US is toast and therefore bonds are screwed too.

If the US becomes toast, whatever caused it to happen, and/or the geopolitical, economic consequences of it having happened, would likely be so enormous that stock and bond prices in your portfolio would be the very least among your problems.

This is almost the definition of technical analysis: “chart always reverted to mean so it will always revert to mean”

Note that almost every exchange outside the US has been flat or negative for decades. The US has held a precious position for a few generations that’s made “chart go up” feel like a given

Kranar · 18h ago
>Note that almost every exchange outside the US has been flat or negative for decades.

As someone who works in finance this struck me as a remarkable claim. Upon inspection it turns out to be spectacularly incorrect. After adjusting for inflation it's actually the opposite, the vast majority of countries have seen their own version of the S&P 500 grow over a 30 year period, after adjusting for inflation, not stagnation or decline. Developing countries, particularly those in Asia, have seen incredible returns over a 30 year period, albeit with a great deal of volatility involved.

Our neighbor to the north, Canada, has seen gains that are slightly below the U.S., but our neighbor to the south, Mexico has seen about the same growth as our own, once again accounting for Mexico's own inflation.

Europe has also experienced a great deal of growth with many European countries even growing moreso than the U.S., for example Germany.

While there are examples of decline, they are in countries that are both poor and have unstable governments. Most countries that are strictly poor but don't suffer from instability have for the most part seen growth rather than stagnation.

So I don't know exactly what led you to believe your claim that "almost every exchange" has been flat or negative, but it's certainly not correct.

kgwgk · 15h ago
> Developing countries, particularly those in Asia, have seen incredible returns over a 30 year period, albeit with a great deal of volatility involved.

The level of the MSCI China index 30 years ago was HKD 70 and it's HKD 75 today. It's kind of incredible but not in a good way. Total return is less than 3% p.a. MSCI Thailand is even worse.

MSCI Korea has a total return of 7% (not bad, 4% above inflation) but it doesn't do better than developed countries.

Of course they look much better if we start right after the 1997 Asian financial crisis but, hey, it was you who talked about "a 30 year period".

kgwgk · 15h ago
> Europe has also experienced a great deal of growth with many European countries even growing moreso than the U.S., for example Germany.

I can't make sense of that example. Are you maybe comparing the level of the S&P 500 with the DAX which is a total return index?

African, Asian, and Latam exchanges included, many of which go defunct. Japan’s has been basically flat among developed countries
Kranar · 16h ago
I don't understand your follow up, are you still maintaining your claim that almost every other exchange in the world has been stagnant or declining?

Worth noting that a stock exchange becoming defunct is not the same as the value of the index associated with the stocks listed on that exchange going to zero.

For example numerous US stock exchanges also go defunct. Nevertheless the value of the stocks that traded on those exchanges remains unaffected. It's not like if NASDAQ went out of business tomorrow that Google and Microsoft would all declare bankruptcy.

And the US itself was flat for over a decade, with the only thing saving a domestic investor's returns being bonds:

Yeah buying Norwegian airlines stock for example would have been a brilliant idea, right. I mean country like Norway with their sovereign fund, oil, very moral population and good government etc, nothing can ever go wrong.
kimbernator · 17h ago
It's hardly fair to portray stock market investment in that way, though. Nobody should be investing in a single stock for 30 years. A diversified sector EFT is just as easy to buy and comes with diversification so a single failing company doesn't have that much of an impact.
scubazealous · 18h ago
Bonds are considered safer because short of the US losing WWIII there is practically no way the US bonds would not pay out or lose value. US Bonds are safe and predictable, backed up by the immense military and resources of the nation.

Investing in Apple 30 years ago would net a much higher return on $5k but even Apple was considered a unsafe investment in the 90s. On the other hand, Enron was considered a safe investment by many but went bankrupt almost overnight and shares became practically worthless.

kgwgk · 15h ago
> there is practically no way the US bonds would not pay out or lose value.

Bonds can "lose value" and they did so quite strongly in 2022/23.

If you bought 20-year bonds in 2020 for $100 they are worth $60 now (and were as low as $55 in 2023). Getting $1 per year is far from compensating the loss.

They will recover gradually until they "pay out" $100 but right now they're underwater.

floundy · 18h ago
The Nikkei 225 is still below its peak value from December of 1989. The US is an outlier in terms of historical average stock market returns and there is no guarantee this outperformance will continue into the future. Actually I'd say it's less likely, given that should it continue, the US market cap will eat the entire world stock market. The US stock market is currently 62% of the world's stock market capitalization.
tokyoseb · 17h ago
The Nikkei 225 may be below its 1989 peak in price terms but you can’t ignore the dividends which an actual investment in the index would have paid during that period. On a total return basis (if you had reinvested the dividends into the index as you received them) the Nikkei passed its 1989 peak in 2021.
deanmoriarty · 17h ago
I struggle to understand why an educated crowd like HN routinely forgets dividends when posting any sort of financial charts. Total returns are what matters.

ManBeardPc · 18h ago
Only if you invested everything in the Nikkei on the height of the market though. Many US companies are pretty global and have a lot of sales outside the USA. In that sense the risk is a lot less concentrated outside of extreme political events.
floundy · 17h ago
Many international companies are global, and have a lot of sales to the US. But I never see anybody using that as a justification for not investing in the US.

As to the Nikkei retort this seems to be hindsight bias and ignorance of historical context, the general consensus at the time (both inside and outside of Japan) was that the Japanese economy was going to take over the world.

I mean... the risk of risky assets is that they won't last that long. Any asset you can look back on having held for a long time, is by definition less risky than you could have been. No?
BlandDuck · 19h ago
Exactly, if it had been obvious at the time that "the market" would deliver a better return, for certain, then nobody would have bought bonds at those prices.

Then bond prices would have declined (and their expected returns or interest rate would have increased) until, in equilibrium, the anticipation was that the stocks and bonds would deliver comparable expected risk-adjusted returns.

JackFr · 17h ago
Very few entities have a 98 year horizon. People sure don't. Some insurance companies do I suppose.

A more interesting graph would be to show me the 30 year return at each point along the way. My gues is that stocks would still mostly come out on top, but not the runaway you see here.

tjwebbnorfolk · 19h ago
"Risk-free" is a popular shorthand for "The US government won't default". But default is far from the only risk inherent in bond ownership.

Risk is the chance something bad happens to you.

Held for 30 years, bonds are eaten alive by inflation. That's a bad thing that happens to you if you hold bonds for a long time.

kgwgk · 14h ago
> Held for 30 years, bonds are eaten alive by inflation.

20-year and 30-year bonds yield 5% today. That's well above inflation expectations.

You can actually buy inflation-linked bonds that are going to pay you 2.5% over inflation for the next 20 or 30 years - whatever happens with inflation.

tjwebbnorfolk · 9h ago
You're talking about making a 30-year duration bet that inflation will not increase. If you call that risk-free, then all I can say is I have a very different idea of what risk means.

I'd argue a much better 30-year bet is that somebody like Coca Cola will be able to charge an amount for their product that reflects whatever happens with inflation much better than betting on a fixed rate of 5% that can never increase.

kgwgk · 6h ago
> You're talking about making a 30-year duration bet that inflation will not increase. If you call that risk-free

I didn’t say anything about “risk-free” (the closest is the second paragraph but you don’t address it at all).

I was clearly commenting on the quoted sentence “Held for 30 years, bonds are eaten alive by inflation” which has not applied since the seventies, doesn’t seem the best assumption going forward, and has an easy solution as discussed.

> reflects whatever happens with inflation much better than betting on a fixed rate of 5% that can never increase.

If your main objective is to beat inflation, getting inflation + 2.50% with certainty seems an attractive proposition! (Inflation-linked bonds have a “fixed” rate on top on inflation.)

Indeed. There's always the story of finding stacks of bills in the wall of granddaddies house despite the fact creditors and the bank were up his ass to the bitter end for medical bills.

Given the ever increasing number of people bankrupted by medical bills, divorce, child support, lawsuits, etc we're quickly moving into a world where it might be foolish to expect assets accessible to a brokerage or bank will still be there by the time you need them.

I believe they mean realizing that if you had invested into stocks instead of money market you'd have likely realized a quite large return. Money markets seek to keep your returns to around inflation.

I believe the first broadly diversified ETF didn't come about until a few years later, so realistically there wasn't an easy way for a retail investor to invest 5k in "the market" back then.

Well, your "5k" figure is still probably accurate. They had much larger minimums at launch.
sokoloff · 15h ago
I graduated in 1993 and going back through my old Quickbooks file, my 1993 IRA contribution went to a broad-based fund at Twentieth Century (now American Century). It was a half-year of working and all I could scrape together was $2000 and they accepted it to invest. I suspect making a mutual fund investment for $5000 (over $10,000 today) would have been possible three years prior.
taeric · 15h ago
Amusingly, for 1993, looks like you maxed out what you could even do in an IRA?

Searching for "Vanguard S&P mutual fund minimum 1993" shows that many had a minimum of 3000? I'm guessing that is the same general search you were doing?

I'm torn, as I want to think this isn't wrong. However, I also remember you could buy a car for 10k EASY in the early nineties. Was a pretty decent sum to make in a year. Especially if it was on top of all other expenses. I'd also hazard that for many, getting a car to commute to a job would have probably been a better investment. (Of course... this is only true if you use the car for the added productivity.)

sokoloff · 15h ago
Interesting that the limit was that low. I remember having to borrow money to make the $2K investment before the deadline, but didn’t realize that was maxing it out. (My dad was the one telling me to do it; I’d have been entirely clueless at that point otherwise.)
taeric · 15h ago
Yeah, 2000 to invest was not a tiny amount back then. I know I felt rich to have an extra hundred or so a paycheck.

That's very fair. Index funds are conventional wisdom now, but I do suspect there was a long time where they were undervalued because fees were high. Now, everyone is encouraged to invest in them and do think the conventional wisdom in 30 years could possibly swing back to real estate or something like "index funds of tech"
kgwgk · 16h ago
> Index funds [...] fees were high

According to https://corporate.vanguard.com/content/corporatesite/us/en/c... they were 0.35% in 1990. Higher than now, but hardly "high".

Of course there are other fees involved and everything was more complex and more expensive.

nosianu · 19h ago
> but when I did the math to see how much more it would have been

I have a suggestion for all the many similar problems around probability: Reframe it to be more correct.

Instead of looking against the arrow of time, backwards with full knowledge ask yourself the corresponding question looking forward, from where you are right now.

And then remember that that was the position you were in back then.

Questions that deal directly or indirectly with probabilities become confusing, and frankly stupid, when you violate the arrow of time and make "backward predictions". One should just not ask that question, not even for fun. They not only make no sense, our psyche suffers when we try, even if just a little.

This is part of another kind of problems: Asking why a given answer is wrong, for example in multiple choice questions. One of the best courses I took was an audio cassette pilot license theory course. One thing the speaker said about the multiple choice part of the exam was this. DO NOT (with a lot of emphasis and repetition in the audio) try to dwell on why a point is wrong. Concentrate on the true statements alone. Reason was similar to why raising the question why person XYS is NOT a pedophile still creates the association in the brains of people exposed to statements like that repeatedly. Apart from that, the number of potential wrong statements exceeds the valid ones by many orders of magnitude.

Similarly, just do not think about problems that deal with probabilities and predictions looking backward. It's just not a valid way to think about them. If you must, reformulate to make them forward-looking.

The problem of words and thoughts is the universe checks their validity only very rarely directly and immediately. If we don't restrain ourselves, our thoughts end up not representing reality more and more. Thinking requires quite a bit of self-discipline, we have to place the missing rails ourselves.

trod1234 · 19h ago
This isn't useful or correct, and ends up being a bit circular getting into the weeds.

The focus should be that the normal math formula for bond valuation doesn't account for yearly real or projected inflation.

Almost everyone I have met doesn't know how to modify the standard formula correctly unless they've already done it at some point in the past. Its not a trivial exercise.

You have to understand the formulas well enough to modify them to account for the loss in purchasing power that compounds yearly, as a difference between the interest rate and real inflation over the bond terms.

Most years, inflation has been well above that 2% margin dramatically impacting the rate of return or real yield.

nosianu · 19h ago
> This isn't useful or correct

The formulas do not help you at all with the knowing. or not knowing, with being able to "predict" the past vs. being able to predict the future! They make assumptions.

I would make the claim my statement is useful for what I said, which was for somebody looking back at a decision of the long ago past with hindsight knowledge.

The post was not about somebody evaluating different investments either.

Oh and thanks, I guess, for completely disregarding that my comment was much more generalized? You threw away the vast majority of it.

trod1234 · 18h ago
The vast majority of your argument's volume was promoting an incorrect way of thinking comparing two unrelated things, for a question not asked or really that useful.

You can't determine logical truth in a stochastic environment except after the fact when there is objective measure; and importantly there is no personal harm in doing this either, which is a direct contradiction to what you said.

You then went way out into the weeds when you started talking about pedophiles, and truth.

Any reasonable reader would throw away the vast majority of what you had to say as useless, or worse unstable.

The underlying concepts you mention indirectly, while correct in a narrow context in psychology, bad choice of example aside, also don't have anything to do with what's being said here in this topic.

The problem is that most people don't know how to invest, and this has been done by purposeful intent. Financial education was removed from centralized education long ago.

Bonds necessarily need to exceed the yearly inflation to retain their purchasing power. People claim these are risk free, but they aren't, even when held to maturity. You lose money from the inflation when the rate of interest is below the inflation rate which it almost surely was given the several decades of almost zero low-interest rates in that time period.

There are some general rules that anyone should know. Rule #1 is don't lose your principal investment (don't lose money). Rule #2 is don't invest in a casino, always manage your risk, and know when its unmanageable. Rule #3 invest in yourself, understand the business, limit debt, and focus on value.

People today don't realize the market has been rigged through a number of convoluted ways into that of a casino.

Price discovery is gone because most transactions happen off exchange in the dark. In 2024, over 50% of transactions occurred off-exchange in dark pools. You then also have payment for order flow, synthetic shares via options through predatory middlemen, and no real law enforcement mechanism for when those big players break the rules; and they do on the regular as they did in GME/FRC, and too many other places to count. You've also got large banks pumping the prices up through non-fractional reserve based debt backing options contracts which they use to yield farm, and profits funneled away from businesses into stock buybacks hollowing them out of any value.

No visibility, no price discovery, no economic calculation. These things fail when about 1/4 of the market is off-exchange, its been at crisis for a long time.

There is no real opportunity for investment when you allow those rules to be broken. Its not an actual investment.

The chart you linked isn't inflation indexed.

I believe the chart below is the one you should have been linking (at least one that's public, the reports I get are subscription only so I can't share those):

https://fred.stlouisfed.org/series/DFII10

Anything less than 4% for a real return of 2-3% after inflation falls under low interest rates, and as you can see 2003-2022 this period matches that criteria, with real negative rates 2011-2013, and 2020-2022.

Notwithstanding all the unstated shennanigans and other changes to try to make the numbers look more palatable on the surface, like the YTM reporting loophole, there is also the backroom deals between blackrock to swap old low rate treasuries for newer treasuries on the taxpayer dime (1), and the abandonment of the fractional reserve system (2020, reserves set to 0% for Basel 3) which call into question more foundational issues of the money system.

> The chart you linked isn't inflation indexed.

Neither was your comment. The alternative reading "You lose money from the inflation when the rate of interest is below the inflation rate which it almost surely was given the several decades of almost zero low-interest REAL rates in that time period" wouldn't have made much sense. The interest rate is below the inflation rate when the real rates are negative - not just low.

> Anything less than 4% for a real return of 2-3% after inflation falls under low interest rates, and as you can see 2003-2022 this period matches that criteria.

How does that support the claim that the rate of interest was almost surely below the inflation rate during and that made you "lose money from the inflation" during that period? That happened only very briefly as you notice.

Investing in bonds didn't "lose money from the inflation" in 1990-2020. Actually it was an exceptionally good period to have bonds!

Buying 10-year bonds one after the other in 1990, 2000 and 2010 you got coupons in excess of 8%, 6% and 3% respectively with inflation rates over those decades around 3%, 2.5% and 2%.

The inflation over the 30 years is below 2.5%. $100 in 1990 was $260 in 2020.

Investing $100 in 10-year bonds in 1990 without even bothering with reinvesting results in over $180 in 2000.

Investing $180 in 10-year bonds in 2000 without even bothering with reinvesting results in over $280 in 2010.

Investing $280 in 10-year bonds in 2010 without even bothering with reinvesting results in over $360 in 2010.

That's more than 4% per annum - compared to an inflation below 2.5%. (I didn't include taxes but there was no reinvestment either and everything is rounded down at every step.)

You also got similar (slightly better) returns if you rolled over the bonds to keep constant duration at 10 years (and even better if you had longer duration bonds). The annualized return of the IEF ETF (7-10 year bonds) since inception in 2002 to 2020 is 4.5% - it definitely didn't "lose money from the inflation" which was just 2.1%.

Rule of 72: time for an investment to double is roughly 72 / the interest rate [0].

  Annual return on small-cap stocks: ~12%
  Time to double: 72/12 ~= 6 years
  Number of doubling periods: 99/6 ~= 16
  Final investment value: ~2**16 ~= $65k ~= $64,417

I've always found it amusing that mathematically it should be the rule of 70, but it's commonly rounded to 72 because the latter has more convenient divisors.

It's also because in the interest rate range we're normally dealing with (5%-10% APR) the approximation of 1+x/100 as 1.01^x in the derivation of the rule is off a bit, and something like 1.0097^x works somewhat better. ln(2)/ln(1.0097) is about 71.8, thus the use of 72 and it's convenient divisors.

Interesting, thanks for sharing this.
Balgair · 15h ago
Oh gosh, 72 is way more anti-prime, I've always just used the rule of 70 in my head though.

if I have a calculator handy, I'll use [(69.3/rate) + 0.3] as that's really close to the actual numbers for rates under about 10 or so.

I'm curious as to what other methods people use.

Honestly, I should probably just memorize the 12 or so numbers.

For those interested, here's a mnemonic that I cooked up quick with chatGPT:

70 bears ate 35 lions who ate 23 tigers who ate 18 wolves who ate 14 dogs who ate 12 cats who quickly ate 10, 9, 8, 7 mice who ate 6.6 grasshoppers who ate 6.1 barleycorns

Look, I know this is not the best, but hey, it's Friday. Please help me out and make up a better one.

70, 35, 23, 18, 14, 12, 10, 9, 8, 7, 6.6, 6.1

Perfect time to revisit the Futurama episode where Fry realizes he's rich. https://www.youtube.com/watch?v=6JwkaLt9pf8
fuzzythinker · 16h ago
I don't watch Futurama, so I may be wrong in how the story goes. But I think he thought that he's rich but inflation shouldn't be much lower than interest (irl, it's actually way higher), so the 4 billion is likely worth 4 bucks or at most 4 hundred.
recursivecaveat · 11h ago
It seems like the episode treats him as legitimately rich, but you're right: assuming targeted 2% inflation, it's like $10. That's being pretty generous too, 1000 years is a long time to go without some kind of societal shakeup event where people stop honoring 800 year old numbers on a screen as legitimately valuable. It's not like there is any entity today who would feel obligated to give you $4 billion dollars for your 11th century banknote.

Note that the government has huge incentives to downplay the inflation rate. Over the time period of the graph, the price of gold went up by about 100x; I would consider that a more accurate estimate of inflation than the 18x number implied by the chart. Due to the way exponentials work, you can hide a lot of inflation over 100 years by claiming the annual rate is just half a percent lower than it really is.
lesuorac · 17h ago
Gold is up ~40% over the past year. Are you really going to claim inflation is up 40% over that time period?

I think Gold is too susceptible to price fluctuations from speculators and that you should use Copper or something that people don't hoard to re-sell.

For reference, CAGR from 1926 to today:

Milk: 2.5% (*low-quality data)

CPI: 2.9%

Copper: 3.4%

Gold: 5.2%

baron816 · 16h ago
Statistics like CPI really aren’t meant to be used to track inflation over many decades. It’s really only meaningful over a handful of years, and only when we’re talking about the economy as a whole (not to use it to say any individual or group is better or worse off). A dollar today can buy many things it could not buy 100 years ago.

The price of gold is a completely useless measure of inflation. Governments have a long history of manipulating its price as a policy goal. Even today, governments buy and hold large quantities of gold.

Lerc · 18h ago
It would be worth seeing the price of a loaf of bread, a dozen eggs, and a bottle of milk.

While not capturing the complexities of modern technology, they are available across the entire period and probably have a closer relationship to people's lives than the price of gold.

The CPI is one of the most studied and examined statistics that the government releases. Everyone from hyper-capitalist financial traders to leftist unions folks (because of CoL contract provisions) examine in and none of these folks who have a vested interested in calling out fraud have stepped forward.

There have been numerous peer-reviewed examinations about it, including open source code:

* https://en.wikipedia.org/wiki/MIT_Billion_Prices_project

There are disagreements about the "best" way to measure certain things (e.g., owner-occupied housing), but for the published methodology there is no cooking of the books that anyone without a tinfoil hat can find.

A recent profile of how the BLS does things:

* https://www.washingtonpost.com/opinions/interactive/2024/joh...

* http://archive.is/https://www.washingtonpost.com/opinions/in...

(Included as a chapter in the recent Michael Lewis (of Big Short fame) book Who Is The Government?)

And regarding gold specifically, there have been periods (that stretch over decade(s)) where gold has been flat, especially in inflation-adjust terms:

The fact that it just happened to pop up over the last 2-3 years is recently bias. Your returns would have been highly dependent on when you got in for each (use slider):

The cool thing about about something with a consistently high return and a long-horizon (going back 100 years) - you're still getting a high return.

It's about ~6% CAGR vs ~8% if you picked the absolute best vs absolute worst time around the Great Depression.

If you include re-investing dividends, it's about ~8% vs ~10%. You're not getting anywhere near that with gold over any sufficiently long non-cherry picked time horizon.

The even better thing about the S&P is it has relatively low volatility. You're really unlikely to put all your eggs in the S&P at the absolute worst timing. Sure, it's possible. Not likely.

This isn't a chart of returns; it's a chart of who had nerves of absolute steel. Be honest, who here has actually lived through a major dip and not been tempted to smash that "sell" button?

>Be honest, who here has actually lived through a major dip and not been tempted to smash that "sell" button?

Honestly, I've lived through four (1987[0], dot-com, 2008 recession, 2020 coronavirus) and was not tempted. For the first two, I was much too far away from retirement to worry about it, and for the third, I was still over ten years away from even beginning to think about retirement distributions, and because of my experience with the first two, again was not tempted. The fact that my investments for much of that time were in pre-tax accounts helped me avoid feeling some pain as well.

Nowadays, I try to keep, in addition to an emergency fund, about a year's worth of retirement distributions in money market equivalents, even inside my IRA.

rufus_foreman · 19h ago
I don't get tempted to smash the sell button during major dips, I get tempted to smash the buy button. The only time I smashed the sell button was during the stock market bubble in 1999.

I wanted to buy during this year's dip but I took a look at my asset allocation and I was still way overweight in US stocks compared to my target so I couldn't justify it. Hopefully people freak out even more next time.

Stock market crashes are my happy place.

trod1234 · 18h ago
I think the same could be said of anyone who has successfully traded regularly over several years.

To do that kind of business you have to have mastered yourself or set up systems where the emotional rollercoaster ride doesn't change your choices.

> I wanted to buy during this year's dip...

The Stock market hasn't had a real crash in quite a long time as evidenced by a number of things including the PE values and stock buybacks, lack of general price discoverability towards chaotic whipsaws and the indexes topping all time highs.

People are going to lose the shirts off their backs when it does come, and it will come suddenly without warning. Best to keep that in mind when greed might try to lead you astray. Greed is both a friend and a trader's worst enemy.

Printing money enrolls participants in boom bust cycles. We've had a boom for the last 10+ years nearly straight. The stock market is way overdue for a crash. Its an avalanche prone area with a massive snowpack built up. There's always some chaotic trigger that gets everything moving again.

dachris · 19h ago
It's a nice graph, I think the most well known one is in "Stocks for the long run" [0]

I'm more concerned how it will grow over the next n (lets say 50) years.

Somehow, it doesn't really fit into my head that there will be another 7 doublings of money invested stock market over the coming 50 years (as others have commented, 10% annually is doubling every 7 years).

Reality is complex of course, there's inflation, there's taxes, dividends don't grow the stock market cap.

Still, I would assume less growth due to several factors. The last few decades have seen several tailwinds that can't repeat in the same way:

- falling corporate tax rates globally [1]

- falling interest rates [2] (since 1980, until 2020)

- rising P/E ratios (partly in response to falling interest rates) [3]

- demographic expansion [4]

- improvements in diversification (index funds, theoretically you need a lower risk premium than when investing in individual stocks)

And I'm not sure that headwinds coming from environmental degradation of many types are already priced in.

I still think that stocks will do better than bonds (there's a risk premium [5], those are real assets, there's innovation and growth), just be cautious about assuming that the future will mirror the past.

I thought the same initially but this may just be a case of recency bias. Small caps have underperformed large cap stocks for the last ~12 years but these things tend to go in cycles: https://blogs.cfainstitute.org/investor/2025/04/24/small-cap....

It will be interesting to see how the next cycle plays out with the recent concentration of returns in large cap tech stocks (Magnificent 7).

Looks like that was a one-time event in the 70s. The rest of the time, the small stocks line goes roughly parallel to the large stocks line.

> But nor does it include owning stocks in companies that go out of business, or indeed, nations.

Which is why you invest in the entire market, internationally diversified. There are now funds (mutual/ETF) that allow you to do this with a single purchase:

* https://www.finiki.org/wiki/Asset_allocation_ETF

ashdksnndck · 14h ago
I think that’s generally included when you compute total return of an index. For example, Enron should be part of the drop shown in 2001.
floundy · 18h ago
Incorrect, the DJIA lost around 90% of its index value in the Great Depression, so the theoretical portfolio in this exercise would have declined to around 10 cents, but holding an asset at a negative return does not result in a margin call if one is not trading with leverage.

In practice, it would have been a toss-up between individuals' outcomes because index funds as we are familiar with them today did not exist at the time. The DJIA was a price index but there was no way to invest in the DJIA basket as there is today, so brokers picked stocks on behalf of investors. So it's certain that some investors' portfolios did decline to zero during this time due to bankruptcies of all the companies they happened to be holding.

… if the dollar is literally stuffed in a mattress or buried in jars in your backyard. Which is not the point of a currency.

Having it drop in value—at a modest, predictable rate—is arguably a good thing:

> No currency should be able to buy the same basket of goods over very long timespans through hoarding. If you want to retain the purchasing power of your money, it should participate in society via investment.

You mean like the great depression which happened not long after formation, which some prominent economists have argued was exacerbated by the fed?

Things did stabilize quite a bit after we bombed the rest of the industrial world into oblivion, though, creating a period of prosperity roughly equal in expansion to the period from the end of the civil war to before the creation of the fed.

9rx · 19h ago
To be fair, while what you say is no doubt true, the Federal Reserve didn't gain the tools that it would now use correct for that until the mid-1930s and in some ways not until the 1950s — when the Great Depression was already well on its way to being over/was ancient history. It was something quite different leading up to/during the beginnings of the Great Depression.
throw0101c · 13h ago
> You mean like the great depression which happened not long after formation, which some prominent economists have argued was exacerbated by the fed?

The tight monetary policy of the Fed (dictated by the rules of then-orthodox gold standard) made the Great Depression worse:

* https://www.nber.org/books-and-chapters/financial-markets-an...

And it was only after leaving the gold standard that countries started to recover:

> In the end, recovery from the Great Depression does not begin until countries give up on the combination of the Bagehot Rule and of commitment to sound gold-standard finance. Those countries that have central banks willing to print up enough money so that people are willing to spend it--it is when you adopt such policies that your economy begins to recover. If you don’t, you become France, which sticks to the gold standard all the way up to 1937, and never gets a recovery. When World War II begins, Nazi Germany’s production--equal to France's in 1933--had doubled between 1933 and 1939. French production had fallen by 15%.

* https://delong.typepad.com/delong_long_form/2013/10/the-grea...

It was the 'sound money' orthodoxy that everyone adhered to that made things bad, and not the Fed specifically. It's not like things were any more stable pre-Fed:

* https://en.wikipedia.org/wiki/Panic_of_1873

* https://en.wikipedia.org/wiki/Panic_of_1893

* https://en.wikipedia.org/wiki/Panic_of_1896

* https://en.wikipedia.org/wiki/Panic_of_1907

And the "Great Depression" used to refer to something else pre-1930s:

* https://en.wikipedia.org/wiki/Long_Depression

It should also be noted that how the Fed (or any central bank) was run one hundred years ago, and how it/they are run now, are two different things. We've learned a lot (sometimes through painful experience(s)) about how to run economy(s).
