The U.S. has the world's largest companies by market capitalization and about two-thirds of the MSCI World Index is dominated by companies based out of America.
What Happened: U.S.-based companies ranking among the world's top ten firms by market capitalization include Apple Inc.
These magnificent seven firms along with Broadcom are the beneficiaries of the U.S. tech and AI boom. The remaining two non-U.S. firms that make up the top ten include Saudi Arabian Oil Co and Taiwan Semiconductor Mfg Co Ltd
According to an X post by Kevin Gordon, director and senior investment strategist at Charles Schwab, "Such an imbalance has not been seen since the late 1980s." The data shared by him shows nine out of the top ten companies by market capitalization were based out of the U.S. in the 1980s.
"...the US, with 4% of the world's population, roughly a quarter of global GDP and a third of global profits, now accounts for more than two-thirds of the MSCI World index's capitalization. Such an imbalance has not been seen since the late 1980s...," he said.
Why It Matters: Additionally, the top ten constituents in the MSCI World index are U.S.-based firms. This index captures 1,397 large and mid-cap companies across 23 developed markets.
According to MSCI's latest release, dated Nov. 29, the U.S. has a weightage of 73.92% in the index, followed by Japan with 5.23%, the United Kingdom with 3.44%, Canada with 3.1% and France with 2.5%.
