The Only Equities Most Investors Should Buy

There are a few simple things that will massively improve the financial performance of most portfolios over time:

  1. Most investors do not have the ability to outperform the financial markets (often called having an “edge”), so as a result, they should invest in index-tracking products. In my recent book, Investing Demystified, I call such people “rational investors.”
  2. By keeping trading to a minimum and investing efficiently with the lowest possible fees, investment portfolios will perform far better in the long run.
  3. To have some hope of respectable long-term financial returns, the portfolio should probably have some equity exposure to avoid the dull returns that safe bonds or cash in the bank currently provide.

But Which Equities Should Most Investors Own?

I believe the only equity exposure that people who agree with the points above should have is in the cheapest, broadest, most tax-efficient index tracker of aggregate world equity markets they can find.

Why? Let’s assume that from the perspective of the rational investor (an investor accepting and embracing the fact that she doesn’t have an edge in the market), each dollar/pound/euro/etc. invested in the stock markets around the world is presumed equally smart.

So while the markets may say a share in Apple is worth $125 and a share in Microsoft is worth $44, we as rational investors do not have a preference for investing an equivalent dollar amount in either company. If we did have a preference, we would effectively be saying that we know more about the future movements in share prices than the aggregate market does, which we, as rational investors, do not.

Therefore, we believe the person buying Apple is no more or less clever/informed than someone buying Microsoft. Applying this logic to the whole market means that we should own shares in all the stocks in the market according to their fraction of the overall value of the market. So if, for example, we assume that the market refers only to the US stock market and that Apple shares represent 3% of the overall value, then 3% of our equity holdings should be Apple shares.

If we do anything other than this, we are somehow saying that we are more clever and more informed — that we have an advantage over the other investors in the market.

Massive Diversification Is Possible — and a Wonderful Opportunity

Thanks to the many index-tracking products now available, buying equity in hundreds of firms on the US stock exchanges in proportion to their respective market capitalizations is much simpler today than it was a generation ago. (In the example above, Apple would constitute 3% of the value of the index tracker.)

But why stop at the US market? If there is $15 trillion invested in the US stock market and $2 trillion in the UK market, there is no reason to think that the latter market is any less informed or efficient than the former — likewise with any other market in the world that investors can get access to. We should invest in them all, in the proportions of their share of the world equity markets within the bounds of practicality.

If you were able to over- or underweight one country compared with its fraction of the world equity markets, you would effectively be saying that a dollar invested in an underweight country is less clever or informed than a dollar invested in the country that you allocate more to. You would essentially be claiming to see an advantage from allocating differently from how the multi-trillion-dollar international financial markets have allocated — which, without some sort of edge, you are not in a position to do.

In addition to it being much simpler and cheaper, since investors have already moved capital between various international markets efficiently, the international equity portfolio is the best one.

Take me as an example. As a Danish citizen who has lived in the United States and the United Kingdom for 20-plus years, I might instinctively be over-allocating to Europe and the United States because I am familiar with those markets. But in doing that, I would implicitly be claiming that Europe and the United States have better risk/return profiles than the rest of the world.

That may or may not be true, but the point is that we do not know ahead of time. You may find yourself making statements like “I believe the BRIC [Brazil, Russia, India, and China] countries are set to dominate growth over the next decade and are cheap.” You may be right, but you would also be saying that you know something that the rest of the world has not yet discovered.

This does not make sense unless you have an edge.

  1. Mr. Kroijer,
    All countries are not the same. All stock markets do not work efficiently. If the market were truly efficient in pricing, the Great Recession would not have occurred, since the value of financial instruments would have been reflected in stock prices in an ongoing basis. Geopolitical risk and corruption are not the same in every country. As a world citizen, you would be aware of the different business practices that occur in Denmark, the U.S., and U. K., relative to China, Russia, or Nigeria. Allocating capital based on market capitalization with no regard to any other factor does not make sense.

    1. John says:

      the issue, as Lars points out, is whether you know more about these business practices than the market — because presumably they are priced in because everyone knows about corruption in Nigeria, etc.

  2. Neil says:

    Way too diversified in my opinion. A disciplined trend-based approach that keeps you in the better underlying trends (be it sectoral or otherwise) which can last for a few months or years will improve performance — and — reduce volatility and drawdown if done right. No guess work – opinion – just data.

  3. omojola jide says:

    Personally, i feel over-diversifying makes you loose control. it becomes difficult to effectively monitor your assets and make quick decisions.

  4. The flaw in this argument is that one can be well diversified by investing passively in capital-weighted indexes.

    By their nature, capital-weighted indexes can become concentrated in a handful of industries pretty easily. In 2000, for example, TMT stocks–technology, media and telecom–the champions of the dot com era, grew to over 40% of the theoretically diversified S&P 500 index. When TMT stocks infamously imploded, they took the index down with them. Peak-to-trough losses for that index were almost 51% (excluding dividends). The results for the NASDAQ were worse.

    The problem exists because the most popular positions, the ones for which no price is too high, become the largest by market capitalization as the underlying shares rise in price. So, yes, equity indexes are difficult for an active manager to beat when markets rise. But, they can be hugely disappointing in declining markets when one needs the benefits of diversification the most.

  5. Ashok says:

    Firstly, the problem with this (article’s) approach is that if you are a financial adviser and the portfolio falls 5% in a month or a year and your client asks you why how would you explain? Imagine the digging attribution involved.

    Secondly, your client’s gonna feel that you are no clever than himself and would discontinue advisory relationship with you if all you are doing is direct his funds towards world-equity indices. If you can’t distinguish between Mozambique and Philippines then there is something seriously wrong.

    Thirdly, remember that it is far easier to make mistakes than being correct. Investing in Mozambique when it’s apparent that not many are doing that is a low-cost signal to catch.

    Finally this passionate passive argument stems from the incorrect belief that equity markets are zero sum games. Theoretically and fundamentally that’s wrong.

  6. Bob Kingsley says:

    I agree. The amount invested and cost are the only two realistic factors one can control year after year. The large majority of actively managed funds do not beat the index funds in any given year and over the long term, even fewer actively managed funds beat the index funds.

  7. Dave says:

    Lars , Eugene Fama (and I) know your thinking is correct. Efficient Market, is continually being proven correct ….
