Oct 20, 2024, 02:54 PM

The market capitalization of the top 10 largest US stocks now accounts for over 18% of the global stock market value, surpassing the Dot-com bubble peak of 9.9% in March 2000. This concentration has doubled in the past five years. Currently, the US market capitalization as a share of the world's total is 61%, the highest since the 1960s and 1970s. If an investor had put $10,000 into the US stock market in 2000, it would be worth $27,000 today, compared to $16,000 if invested in the rest of the world. The US market cap growth rate has significantly outpaced global GDP growth post-GFC, with US market cap growing at 14.1% annually compared to the nominal world GDP growth of 3.9% per year. The US market cap is currently 220% of US GDP and has been growing steadily since 2010.
