Datadog shares rose over 9% in after-hours trading Wednesday after S&P Dow Jones Indices announced the company will join the S&P 500, according to Benzinga. Datadog will replace Juniper Networks, which was acquired by Hewlett-Packard Enterprise earlier in the day. The change takes effect before the market opens on July 9. Datadog offers monitoring and security tools for cloud applications. Shares of Robinhood, AppLovin, Interactive Brokers, and Carvana slipped, as each had been viewed as a possible S&P 500 addition. Robinhood dropped 2.3% in after-hours after hitting record highs earlier in the session.
