Foreign stocks just feel so... foreign: Fisher's financial mythbusters

Does even the phrase 'foreign investing' give you shivers? Do foreign stocks just seem so... foreign? You're not alone.

Far too many investors wholly ignore the outside world. Or they may consider foreign investments an inherently 'riskier' asset class, holding just 10 or 20 per cent. Too little!

I've heard even established professionals claim foreign is 'riskier'. Riskier than what, they don't say. This is easily disproved with free public data and a bit of history.

The truth is that foreign equity and bond investing shouldn't be any more or less risky than domestic investing. A good, well-diversified equity portfolio will benefit from being mostly in non-UK stocks.


Seem outrageous? It's not. The UK is the world's oldest stock market, but it's only about 7 per cent of the developed world equity markets*.

Considering the whole world - undeveloped markets too - it's about 6 per cent*. If you're UK only, you miss a world of opportunity, plus extra diversification benefits.

Once upon a time, maybe it made some sense for UK individual investors to ignore the non-UK world.

Transaction costs for foreign stocks on foreign exchanges could be excessive, eating into potential benefit. And we couldn't always count on complete transparency from non-UK firms.

But in recent decades, as exchanges have gone electronic, trading globally has become quick and easy - you can buy lots of Chilean stocks as easily as any British stocks.

And in developed nations and even in many (if not most) emerging markets, accounting standards are normalised for publicly traded firms.

Whether buying a French, Brazilian or US stock, accounting and reporting obligations are largely the same. Sure, there are currency fluctuations, too - but they also iron themselves out over time.


If non-UK stocks were materially riskier, returns would be wildly variable. But they're not!

UK and non-UK stocks are more correlated than people think, and it's been that way for a long time (in my 1987 book The Wall Street Waltz, I have scads of charts showing strong correlations between markets going back centuries).

We live in a global economy and always have (at least much more so than people have commonly appreciated, as documented in that book) - and many of the same macro-economic forces acting on UK stocks at any one time also impact non-UK stocks.

Figure 1*** (below, click to enlarge) shows UK and non-UK annual stock performance as measured by the MSCI UK and MSCI World ex-UK indices.

Generally, when one is up, the other is too; UK might be up or down more than foreign, or vice versa, but they tend not to go in opposite directions. If UK stocks are down a lot, foreign stocks are down too.

It's a question of degree. There can be big divergences, but they're shortlived. Since 1970 (as far back as we currently have exceptionally good data), UK stocks have annualised 10.2 per cent and world stocks 9.7 per cent (measured in pounds)**.


There's just no reason to believe, going forward, that one or the other will be inherently better or inherently riskier over long periods. But the two together are overall more stable with less volatility than either by itself. Hence the diversification is worthwhile.

With this great diversification you are fundamentally reducing risk by fully investing globally. Think this through another way.

Many complain endlessly that the UK is doing wrong things socially and politically, and that will cause Britain to no longer have the global leadership position it held for so long. Well, maybe that's true; maybe it isn't. But if you have those fears, that is even more reason to globally diversify.

In fact, by not investing as broadly as you can, you could be missing opportunities to manage risk! But thinking you can't benefit from foreign stocks is bunk.

There's enough difference year-to-year between UK and non-UK stocks to reap benefits from diversification. So stop being a stranger to foreign and go fully global.
