Here are the most recent stock upgrades and downgrades by Seeking Alpha analysts.

Upgrades: 

Broadcom (NASDAQ:AVGO) upgraded to buy from sell by Prop Notes. "The recent selloff in AVGO stock represents a historic opportunity to climb aboard this long-term opportunity. While the valuation still appears somewhat premium, we'd argue that this is ultimately one of the better prices to get involved."

Super Micro Computer (NASDAQ:SMCI) upgraded to buy from hold by Anna Sokolidou. "Assuming no further accounting issues and a continued AI boom, SMCI stock appears highly undervalued and presents a bullish investment opportunity."

Nike (NYSE:NKE) upgraded to buy from hold by Daniel Jones. "Despite recent economic challenges and tariff impacts, Nike's stock has dropped significantly, making it an attractive buy for long-term investors seeking quality."

Caterpillar (NYSE:CAT) upgraded to buy from hold by Luca Socci. 

Otis Worldwide (NYSE:OTIS) upgraded to buy from hold by Michael Duke. 

Scotts Miracle-Gro (NYSE:SMG) upgraded to hold from sell by Seeking Profits.
