How Much "Tech" Do You Own?

July 1, 2024 Jeffrey Kleintop
Owning only the U.S. stock market likely means being overweight Tech. But Tech stocks don't always outperform. Investors may want to look outside the U.S. to be diversified.

It seems that France's stock market has been hit by the uncertainty generated by President Macron's unexpected call for an election, with the second round occurring next weekend. Meanwhile U.S. stocks have continued to climb. But is this the whole story? What best explains the relative performance of the U.S. versus other stock markets over time? Politics? Economic growth? Inflation? Currency? All of these can matter, but history shows the main factor influencing performance is sector exposure.

The relative performance of the U.S. stock market versus France's can largely be explained by the difference between the performance of the global Information Technology (Tech) sector and the global Industrial sector. The chart below shows the performance of the U.S. stock market versus the French stock market in blue over the past decade (the S&P 500 index divided by the MSCI France index), and the performance of the Tech sector versus the Industrials sector in orange (the MSCI World Technology index divided by the MSCI World Industrials index). The French stock market is dominated by Industrials, composing 26% of the MSCI France index, compared with 8% exposure for the United States. The U.S.'s S&P 500 has 33% exposure in the Tech sector while France has just 4%. To clarify, French stocks do not dominate the MSCI World Industrials index. In fact, U.S. stocks have the highest weighting in both of these indexes—which is unsurprising since U.S. stocks make up greater than 50% of the parent MSCI World Index.

The point is that despite politics and other macro factors, it is sector performance that is likely the primary driver of markets' relative performance. The U.S. stock market (S&P 500) has tended to perform in line with the Tech sector (MSCI World Technology Index), as you can see in the chart below. Measured statistically, the correlation between their performance is a very high 0.92 on both a monthly and weekly basis over the past 10 years and on a daily basis over the past two years. That isn't a perfect relationship, but a very strong one.

If the U.S. behaves like the world's Tech sector and France like the Industrials sector, what sectors align with the performance of other countries' stock markets? Australia tends to behave like Materials, Canada like Financials, and the United Kingdom like the Energy Sector.

United Kingdom

The U.K. is a big producer of Brent crude oil, the global energy benchmark grade produced in the North Sea. The U.K. stock market is highly exposed to the Energy sector with just two oil companies, BP and Shell, accounting for nearly 50% of the earnings of the MSCI United Kingdom Index as of the first quarter of this year. The Energy sector currently makes up 13% of the U.K. stock market compared to just 4% in the U.S.'s S&P 500. Therefore, it may be no surprise that the total return of the U.S. relative to the U.K.'s stock market closely tracks the relative performance of the world's Tech and Energy sectors.

Australia

Iron ore is Australia's top export; BHP, the world's largest metal producer, is headquartered there. Materials stocks make up 21% of the MSCI Australia Index compared to only 2% in the U.S.'s S&P 500. It logically follows that the relative performance of the U.S. and Australian stock markets tracks the relative performance of the world's Tech and Materials sectors, as you can see in the chart below.

Canada

Canada's biggest stock market sector is Financials at 35% of the index, including big names like TD Bank and Royal Bank of Canada. This compares to 12% exposure in the U.S. stock market. The relative performance of the U.S. and Canadian stock markets tracks the relative performance of the world's Tech and Financial sectors, as you can see in the chart below.

U.S.

It may be worth reviewing how much Tech-like exposure investors may have in their portfolios if they are concentrated in the U.S., rather than being more globally diversified.

At Charles Schwab, the sectors we favor in the second half of this year are: Financials, Energy, and Materials, as you can find in our monthly Sector Views publication. This suggests we see the potential for outperformance by the U.K., Australia, and Canada in the months ahead.

But rather than concentrate in a few other countries that also behave just like one sector, broad diversification may be preferable. As you can see in the chart below, the performance of the U.S. relative to the rest of the world is similar to the performance of the Tech sector versus all other sectors. While there was some deviation in the relationship during 2022's bear market, when the U.S. performed relatively well, even as the Tech sector lagged, the divergence was temporary.

Over the past 10 years, the U.S. has had different political parties in office, different rates of economic growth and inflation, Federal Reserve rate cuts and hikes, yet the relative outperformance by U.S. stocks appears to have been primarily the result of Tech exposure. The U.S. will likely remain connected with Tech in the future as it has historically, but Tech stocks don't always lead the stock market. For example, Tech was the best-performing sector in the 1990s, then it was the worst for the 2000s. Investors may want to consider some diversification away from a heavy concentration in Tech should the outperformance over the past decade not persist.
