The 6 U.S. Major Companies Occupy S&P 500 On 30% On The Stock Index

It should be noted that the S&P 500 index is weighted by the market value of stocks.

This rise is driven by a company “NVIDIA” , whose stock price has risen 20% since its strong sales forecast last week showed that spending on AI computing remains strong. The chip maker has added $1.6 trillion to its market value this year and is close to surpassing “Camel” As the second largest company in the world by value.

The transformation of the American market

The S&P 500 is usually dominated by large companies, but not to this extent. The share of the six largest stocks in the index has not exceeded 20% over the past three decades. Their share did not exceed 20% until 2020.

In another sign of the shift in the market, even at the height of the dot-com bubble in 2000, only three of the six largest companies belonged to the technology sector: Microsoft, Cisco and Intel. The other three were General Electric, Exxon Mobil, and Walmart.
