> 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 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.

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.

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

>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

>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.

> 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".

> 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

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:

And as a Canadian, there are different sectors that would have given me positive gains over the years (I generally own mostly VEQT, a globally-diversified ETF):

And it's perhaps looking more closely at what specifically about the US has been positive:

> Looking at this data, there are two distinct periods of extended U.S. outperformance—the late 1990s and today. And what do these two periods have in common? The rise of U.S. technology stocks. Bespoke Investment Group recently created this chart illustrating this phenomenon:

> Now that the U.S. technology sector makes up over 30% of the S&P 500 (as it did back in 2000), this begs the question: Is U.S. outperformance just a technological fad?

Outside of tech, how much better is the general US market than any other market?

The thing is, we do actually have a tech industry and other countries largely do not. It’s like arguing that industrialized nations are only wealthier than agricultural nations if you include manufacturing. Thats the whole point!

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.

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

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.

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.
