DigitalOcean Holdings, Inc. (DOCN) saw its stock price soar 5.67% in after-hours trading on Tuesday.
The significant move follows news that the cloud platform company is set to be added to the S&P MidCap 400 index. This change is part of a broader index reshuffling, where Casey's General Stores will join the S&P 500, and in turn, DigitalOcean will take its vacated spot in the mid-cap index. Consequently, REIT Broadstone Net Lease is slated to replace DigitalOcean in the S&P SmallCap 600.
Stocks often experience price movements around such index changes as funds that track these benchmarks adjust their portfolios to reflect the new composition. The after-hours surge suggests investor anticipation of potential buying pressure from index-tracking funds following the official migration.
