What are the largest companies in the S&P 500?
The companies that make up the S&P 500 index are selected by the committee based on a variety of criteria. Company rankings are adjusted quarterly. Some of the selection criteria include the company's market capitalization, liquidity, fixed domicile, industry classification, and listed exchanges.
Certain selection criteria are necessary; for example, a market capitalization of at least $9.8 billion and a minimum monthly trading volume of at least 250,000 shares. Candidate companies must also trade in the US and be listed on the New York Stock Exchange or NASDAQ at the same time. Despite this, some of the companies in the index never operated in the US, or were once headquartered in the US, but have now moved to other countries.
The top 10 S&P 500 companies include: *
$Apple (AAPL.US)$
$Microsoft (MSFT.US)$
$Amazon (AMZN.US)$
$Meta Platforms (FB.US)$
$Tesla (TSLA.US)$
$Alphabet-A (GOOGL.US)$
$Berkshire Hathaway-B (BRK.B.US)$
$Johnson & Johnson (JNJ.US)$
$JPMorgan (JPM.US)$
So as long as the leading US companies perform well, the S&P index will naturally rise!
