Take a look at the companies making headlines in midday trading. Netflix — Shares of the streamer rose 1% after Seaport upgraded its shares to Neutral Buy.

Revenue was $100.81 billion, missing consensus estimates of $101.76 billion, according to LSEG. UnitedHealth did beat earnings estimates, however, with adjusted earnings of $6.81 per share, compared with analysts’ expectations of $6.72 per share. DigitalOcean Holdings – Morgan Stanley raised the software company’s weight from “equal weight” to “overweight,” sending shares up about 3%. The company said DigitalOcean’s stock did not reflect its ability to serve large customers and had “little trust” in artificial intelligence and machine learning opportunities.
