Palantir shares slid over 4% after the latest S&P 500 snub.
CEO Alex Karp been boasting since last summer that Palantir's strong results make it eligible for inclusion in the S&P 500. However, S&P just released its latest update for the index, and Palantir has been snubbed but included Super Micro Computer and footwear designer and distributor Deckers Outdoor Corp.
The changes will take effect on March 18.
Inclusion in the S&P 500 typically benefits stocks as index funds holding portfolios that mirror the index are obligated to buy them to maintain the weightings of the constituent stocks. Additionally, the increased trading volume and liquidity due to purchases by index funds and ETFs further bolster the stock’s value.
