President Donald Trump’s looming trade war is no friend of the U.S. stock market, and that’s bad news for U.S. investors who like to keep their money at home.
Free trade is under siege. The White House imposed $50 billion in tariffs on Chinese imports on Friday. China responded in kind. President Trump is now threatening up to $400 billion in additional tariffs, and China is vowing to retaliate again. Its Ministry of Commerce called for “comprehensive quantitative and qualitative measures” if the U.S. imposes additional tariffs.
The intensifying trade dispute should worry investors who are reluctant to venture overseas, and there are many of them. According to one estimate, U.S. investors, on average, allocate just 15 percent of their stocks to foreign markets. That’s a huge home bias given that the U.S. accounts for roughly half of global stocks by market value and a quarter of the world’s economic output.
Proponents of home bias argue that U.S. stocks provide plenty of exposure to foreign markets because large U.S. companies sell their wares all over the world. The percentage of S&P 500 sales from foreign countries was 43.2 percent in 2016, according to S&P’s most recent global sales report. That percentage has been reliably between 43 percent and 48 percent since 2006.
