I see diversification not only as a survival strategy, but as an aggressive strategy because the next windfall can come from a surprising place. ” – Peter Bernstein
What is the most universally listed belief in all investing?
Just think about it.
Our voice should have “investors have US shares.”
It is well established that US shares perform historically better than bonds over time, and US shares have also surpassed the most foreign stock markets and other asset classes.
How often have you seen a version of this graph?
Figure 1 – Asset Class Returns
It feels like the US shares have always been composed about 10% forever, and the crazy math result is that if you worse an investment of 10% for 25 years, you have 10 times your money, and after 50 years 100 times your money.
$ 10,000 that was laid down at the age of 20 would grow to $ 1,000,000 in retirement. Amazing!
In the past 15 years it has been even better than that. American shares have been exacerbated about 15% per year since the soil of the worldwide financial crisis, so that almost every actively performed better during this period. These excellent performances have led to an almost universal conviction that US shares are ‘the only game in the city’. Beliefs lead to behavior from the real world.
Don’t get us wrong now Long -term shares Is one of our favorite books of all time. Indeed, American shares probably should have to Be the starting point of the basis for most portfolios.
But it feels like everyone is “everything in” on our shares. A recent survey From the Twitter followers of Meb discovered that 94% of people said they have our shares. That is no surprise. But when everyone is on the same side of the same trade, well, that is usually not a recipe for long -term outperformance.
Despite US shares that are good for around 64% of global market capitalization, most American investors invest almost all their share portfolio in US shares. That is a large betting with overweight on US shares versus the index assignment. (If you are this, knock on your back, because American shares have surpassed almost everything in the last 15 years, which feels like a whole career for many investors.)
We are currently at the highest point in history for shares as a percentage of household assets. Even higher than in 2000.
Given the recent evidence, it seems that investors can be served well by placing all their money in US shares …
So why are we about to question this holy cow of investing?
We believe that there are many paths to build wealth. Trusting a concentrated bet in just one asset class in just one country can be extremely risky. Although we often hear investors that their investment in the American market capital indexes describes as ‘boring’, that experience has been historically anything but.
Consider, US shares fell by more than 80% during the large depression. Many investors can remember the more recent internet bust and global financial crisis where shares fell by about half during every bear market.
That doesn’t sound boring.
US shares can also go very long periods without generating a positive return after inflation or even something that is as boring as cash and bonds. Do 68 years shares that are lagging behind bonds Does it sound like much? Most people struggle with only a few years of underperformance, try a lifetime!
So let’s do something that would not do any healthy investor around the world.
Let’s get rid of your US shares.
Say what?!
This step will probably immerse any portfolio to failure. Investors will eat cat food at retirement. Right?
Let us check our prejudices at the door and try a few thought experiments.
We will investigate one of our favorite portfolios, the Global Market Portfolio (GAA). This portfolio tries to replicate a broad allocation where you have every public possession throughout the world. This total is more than $ 200 trillion as the last that we have checked.
If you end the portfolio tutoring today, this is about half of the bonds and half the shares and have roughly us and half of them. There is also a bit of real estate and raw materials thrown in, but a lot of real estate is held privately, just like agricultural land. (We are investigating different models for activity location in my free book Global allocation of assets.))
This portfolio could be called the real market portfolio or perhaps “assets allocation for dummies”, because you actually don’t “do something”; You simply buy the market portfolio and go through your company. Shocking, this asset spread has traditionally been a fantastic portfolio. In the recent article, “Do Calper’s have to dismiss everyone and just buy a few ETFs?”, Neb has even shown that both the largest pension fund and the largest hedge fund in the US have a hard time beating this basic portfolio “Do Nothing”.
What if you decided to remove US shares from that portfolio and replace it with foreign shares? Certainly, this insane decision would destroy the performance of the portfolio?!
Here is the GAA portfolio and GAA portfolio ex -american shares with risk and return statistics back to 1972.

Almost no difference?! These results cannot be true!
You lose less than half of one percent in annual compound returns. Not optimal, but still completely in order. Every time you reduce the universe of investment choices, risk and return figures often decrease due to decreasing width.
When we have presented these findings to investors, the standard reaction is disbelief, followed by an assumption that we must have made a mathematics error somewhere.
But there is no mistake. You can hardly see the difference when you keep an eye on the Equity curves of the two series.

If you zoom out in the last 100 years and perform the simulation, the results are consistent – about a difference of 0.50%.
You probably don’t believe us, so let’s perform another test.
Do you remember the old Coke vs. Pepsi taste tests?
Let us perform the investment equivalent to see how biased you are. Below are two portfolios. Which would you rather have?

It is quite difficult to see the difference, right?
This can surprise you, but column A is US shares. Column B is a portfolio that consists of foreign shares, bonds, reit’s and gold, with a little leverage. (Our friends at Leuthold call the concept the Donutportfolio.)
Both portfolios have almost identical risk and return statistics.
The surprising conclusion – You can replicate the historical return flow of US shares without having US shares.
There is no reason to stop here …
It is very easy to build a historic back test with many superior risk and return statistics than what you would only invest in US shares. Moving from market capitalization, US shares weighed to something like a return approach from shareholders, has historically added a few percentage returns in simulations. Additions such as a trend after approach can be enormously additive in the time in the field of diversification and risk reduction. We believe that investors can achieve a higher return with lower volatility and attract these additions. For more information we would lead you to our old Trinity portfolio WhitePaper …)
Although they do not necessarily need our shares, they are the starting point for most of us. They are nice to have, but you don’t have to own them, and certainly not with the entire portfolio.
Because the American stock market shows some cracks while acting in the vicinity of record valuation area, it may be time to reconsider the almost universally held holy faith …
“You have to be completely in the US shares.”
