Paramount Global — Shares of the entertainment giant popped 5.6%. The Professional Fighters League announced on Monday that it completed its acquisition of mixed martial arts brand Bellator from Paramount. Penn Entertainment — The gambling stock jumped 6.8% on the heels of a Bank of America upgrade to buy from neutral. The firm said shares could get a boost from ESPN Bet, the company’s new sportsbook. Spectrum Brands Holdings — Shares dipped 2.5% after Wells Fargo downgraded the home essentials company to equal weight from overweight, saying it is less convicted about fundamentals. Microsoft — Shares jumped about 2% after Microsoft announced that former OpenAI CEO Sam Altman and president and board chair Greg Brockman will be joining the tech giant to head a new artificial intelligence research team. Analysts viewed the hirings as a positive catalyst for Microsoft in the long term. Nvidia — The chip giant’s shares rose about 2.3% and reached its all-time high on Monday.

Boeing — The aerospace stock jumped roughly 4.7% after Deutsche Bank upgraded the shares to a buy rating from hold. The Wall Street firm said aircraft deliveries are accelerating, which could carry through to a positive inflection in free cash flow revisions. Chegg — Shares of the education technology company dropped 6.2% following a downgrade to underweight from equal weight by Morgan Stanley. The bank said the stock’s recent run higher created an unattractive risk/reward and noted Chegg is seeing weaker web traffic and download trends.

Analysts said that although Krispy Kreme has enormous underlying appeal, the company has execution issues.
