Wednesday brought a wave of optimism from Wall Street analysts, who shifted their stances on several high-profile companies. Here's the rundown of the top five upgrades worth watching.

Home Improvement Gets a Lift

Barclays analyst Seth Sigman upgraded Lowe's Companies Inc (LOW) from Equal-Weight to Overweight with a price target of $285. The home improvement retailer closed at $246.49 on Tuesday, suggesting Sigman sees meaningful upside from current levels. The move signals growing confidence in Lowe's ability to navigate the housing market environment.

Biotech Gets Another Look

Bank of America Securities analyst Tim Anderson made one of the more dramatic moves, upgrading Regeneron Pharmaceuticals Inc (REGN) from Underperform to Buy and raising the price target from $627 to $860. That's quite the turnaround in sentiment. Regeneron shares closed at $776.54 on Tuesday, meaning Anderson sees about 11% upside from here after previously having a negative view on the biotech giant.

Lithium Producer Catches a Bid

Baird analyst Ben Kallo upgraded Albemarle Corp (ALB) from Neutral to Outperform and nearly doubled the price target from $113 to $210. Albemarle, a major lithium producer, closed at $158.15 on Tuesday. The upgrade comes as the firm apparently sees better days ahead for the lithium market after a brutal downturn.

Sweet Spot for Chocolate

Piper Sandler analyst Michael Lavery upgraded Hershey Co (HSY) from Neutral to Overweight and raised the price target from $193 to $213. The chocolate maker closed at $179.28 on Tuesday, giving Lavery's new target nearly 19% upside potential. The upgrade suggests the analyst sees Hershey navigating cocoa price pressures and consumer demand better than expected.

Banking on BNY Mellon

Truist Securities analyst David Smith upgraded Bank of New York Mellon Corp (BK) from Hold to Buy and raised the price target from $119 to $134. The custody bank closed at $121.31 on Tuesday, just above Smith's previous target, prompting the analyst to see more room to run as the financial services environment improves.

These upgrades reflect shifting analyst sentiment as firms reassess their outlooks heading deeper into 2025. Whether these calls prove prescient remains to be seen, but they certainly signal where some of Wall Street's smartest minds are placing their bets right now.
