Every year, China gets closer to catching the U.S. as the world’s biggest economy. When it comes to their stock markets, however, there’s no contest. Since 1992, China’s GDP has grown 6.5 times as fast as America’s—but U.S. stock returns have been 3.5 times as high.
Indeed, U.S. stocks have dominated global investing, as measured by market capitalization, for most of the past 125 years. For that, you can partly thank New Deal–era regulations that tamed the Wild West of U.S. markets, making them attractive to risk-averse investors worldwide. And compared with China, where state-owned companies drive the economy, the U.S. gets more growth from publicly traded companies. But supremacy can be fleeting. Just ask Japan, whose markets soared in the late 1980s, only to nose-dive amid asset bubbles and massive overborrowing. In other words: Don’t get too cocky, U.S. stock bulls.
