Here are the latest Seeking Alpha analyst rating upgrades:

Tesla (NASDAQ:TSLA). Sell to hold by Stone Fox Capital. "The key investor takeaway is that TSLA stock provides crucial support around $220. If this holds, an investor can play the robotaxi opportunity, with Tesla likely to rally heading into this supposed launch in Austin in a few months. If the stock doesn't hold, an investor probably wants to head towards the sidelines and avoid the stock."

Tesla (NASDAQ:TSLA). Hold to buy by Livy Investment. "There are multiple imminent upside catalysts in place for TSLA stock that shouldn't be overshadowed by ongoing market fears and tariff uncertainties."

Palantir (NASDAQ:PLTR). Sell to hold by Juxtaposed Ideas. "Despite the correction, PLTR remains inflated compared to peers, with the limited near-term recovery catalysts yet deserving a Buy rating."

DuPont (NYSE:DD). Sell to hold by Blue Chip Portfolios. "While the China probe is a clear negative for the stock, I believe the stock's valuation fully reflects this risk. I am upgrading the stock to Hold as I believe the risk-reward is now more balanced than was previously the case due to DuPont's more attractive valuation."

Levi Strauss (NYSE:LEVI). Hold to buy by Daniel Jones. "Revenue, profits, and most cash flow figures are growing nicely. Shares have also become cheaper and are now attractively priced, especially relative to similar companies."

Walgreens (NASDAQ:WBA). Sell to hold by Envision Research. 

United Natural Foods (NYSE:UNFI). Hold to buy by Caffital Research.
