It's a good week for S&P 500 (Index: SPX) snapshots, where we're focusing on the index' market capitalization in this update.
But not just of the index as a whole. We've also identified the Top 10 firms making up the 505 stocks that make up the current composition of the S&P 500, where we find they collectively account for 27.8% of the index' entire market capitalization of $37.15 trillion.
The other 495 firms in the S&P 500 have a collective market capitalization of $26.8 trillion. That figure, coincidentally, was the entire market capitalization of all the companies of the S&P 500 back on 31 July 2020!
Here's the list of the top 10 components of the S&P 500 index:
- Apple (NASDAQ: AAPL)
- Microsoft (NASDAQ: MSFT)
- Amazon (NASDAQ: AMZN)
- Facebook (NASDAQ: FB)
- Alphabet (A) (NASDAQ: GOOGL)
- Alphabet (C) (NASDAQ: GOOG)
- Tesla (NASDAQ: TSLA)
- Berkshire Hathaway (B) (NYSE: BRK.B)
- Nvidia (NASDAQ: NVDA)
- JP Morgan Chase (NYSE: JPM)
The top two firms, Apple and Microsoft, have market caps in excess of $2 trillion each. Amazon, which ranks third, has a market cap of nearly $1.4 trillion. If we combine the market cap for the two classes of Alphabet stocks, the firm formerly known as Google would have a market cap in excess of $1.5 trillion. Separately, both Alphabet stocks fall below Facebook, which ranks fourth among the individual stock listings, having a market cap in excess of $854 billion.
Dropping down the list, Tesla has surged into the Top 10 of the S&P 500's components since our last snapshot from August 2020. Nvidia also joins the list in this edition.
Meanwhile Berkshire Hathaway carries over, but Johnson & Johnson has dropped out of the top ten, replaced by JP Morgan Chase.
