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. 70 is divisible by 1, 2, 5, 7, 10, 14, 35, 70 72 is divisible by 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
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.

#42If we're allowed to cherry pick years, now do gold https://sprott.com/media/3783/fig1-jh-gold-perf.png
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.

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

#44It'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, ther…

I'm not sure that a US government bond has a meaningfully different risk profile than an aggregate investment in US equity markets.

"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.
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.

#47This 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?
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…
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.

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

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.

#50When 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.
A surprising number of 401(k) plans default to a money market fund for invested assets. Imagine retiring after a decades-long career and realizing what could have been.
I'm not following what this means. Can you please elaborate?
