How Much "Tech" Do You Own?

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.

Indexes are unmanaged, do not incur management fees, costs, and expenses and cannot be invested in directly. Past performance is no guarantee of future results.

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.
