Each year, Dimensional analyzes investment returns from a large sample of US-domiciled funds (over 4,000). This year’s study updates results through 2022 and includes returns from mutual funds and exchange-traded funds (ETFs) domiciled in the US. The evidence shows that a majority of fund managers in the sample failed to deliver benchmark-beating returns after costs. We believe that the results of this research provide a strong case for relying on market prices when making investment decisions.

The charismatic character in the photo above is a marketing genius and a provocative thinker. His name is Seth Godin. Long-time friends know that I’m a Seth Godin Superfan. Call me a “Sethy.” Much of his writing reflects his strong belief in taking the long view.

Seth often says, “People like us do things like this” when fellow tribe members connect their values with how they live their lives. In particular, Seth sounds like us…clients, team members, and other evidence-based investors in this recent post. See if you agree.

As an investor, it’s natural to be drawn to invest in your “home” market. The United States is where you live and work. You know the companies, politics, and economic climate. It also doesn’t hurt that the returns of the U.S. market have been fantastic over the last decade. From 2010-2022 the S&P 500 has returned an average of 12% annually.

In comparison, over the same period, the MSCI All Country ex US index, representing global stocks excluding the US, returned an average of 3.5% annually. These figures might lead one to question the need for global diversification. I’m here to convince you that diversification is, in fact, “the only free lunch” in investing.

History has demonstrated the importance of looking beyond recent performance and that any country, even successfully developed ones, can have long periods of sustained underperformance.

For example, let’s start by looking at the United States for the decade directly before the one mentioned above. From 2000-2009, known as “the lost decade,” the S&P500 had an annualized return of -1%, while the MSCI World ex US index had an annualized return of 1.6%. Over this decade, investors lost money by investing in the US stock market and had 27% less money than an investor who invested in global ex-US equities.

Another example is Japan. In 1989, Japan held the title of the world’s largest stock market. With a total market cap of approximately $4 trillion USD, iconic companies like Toyota, Sony, and Honda were global industry leaders. Japan had a diversified economy and was widely regarded as the world’s technology hub. During the 1980s, the Japanese market grew from $0.5 trillion to $4 trillion, with the Nikkei (Japan’s equivalent of the S&P 500) delivering impressive annual returns of 19.5% from 1980 to 1989. At that time, the US stock market’s size was smaller than that of Japan at around $3 trillion.

However, fast forward 35 years, and the picture looks starkly different. Today, the US market is valued at a staggering $40 trillion, while the Japanese market lags behind at approximately $5 trillion USD. Notably, Japan experienced no runaway inflation, wars, political turmoil, social unrest, or famine during this period. Despite its once fast-growing market and technological prominence, the Nikkei grew by less than 1% annually over the next 35 years. This is a powerful reminder that even the most promising markets can encounter prolonged stagnation.

The tale of Japan’s rise and subsequent stagnation highlights the importance of global diversification. While recent US market returns have been remarkable, investors must consider the broader global landscape and the potential risks of concentrating investments solely in one country. By embracing global diversification, investors manage risk, gain exposure to diverse opportunities, and position themselves to capture long-term growth potential. A well-diversified portfolio provides resilience, protects against overexposure to a single market, and helps navigate the uncertainties of the global economy.
