Wall Street analysts shuffled their ratings Monday morning, issuing upgrades across a diverse set of sectors. Here's what changed and where analysts see opportunity heading into the week.

Datadog Wins Over Morgan Stanley

Morgan Stanley analyst Sanjit Singh upgraded Datadog Inc. (DDOG) from Equal-Weight to Overweight while maintaining a $180 price target. That's a substantial vote of confidence given the stock closed Friday at $125.49, suggesting Singh sees roughly 43% upside potential. The monitoring and analytics platform has been navigating a challenging environment for software spending, making this upgrade particularly notable.

Pool Corp Gets A Refresh

Baird analyst David Manthey flipped his stance on Pool Corp (POOL) to Outperform from Neutral, though he trimmed his price target from $345 to $320. Even with the reduced target, there's meaningful upside from Friday's close of $252.28. Manthey apparently sees the swimming pool supplies distributor as oversold, despite moderating his expectations somewhat.

Amphenol and the Connectivity Play

Barclays analyst Guy Hardwick upgraded Amphenol Corp (APH) from Equal-Weight to Overweight and raised his price target from $143 to $156. The connector and cable manufacturer closed Friday at $140.16, positioning it just below Hardwick's new target. The upgrade suggests confidence in the company's exposure to data center and communications infrastructure buildouts.

Albemarle's Lithium Bet Gets Bigger

Scotiabank analyst Ben Isaacson issued one of the more dramatic calls, upgrading Albemarle Corp (ALB) from Sector Perform to Sector Outperform while boosting his price target from $85 to $200. That's a massive increase, especially considering the stock was at $161.29 on Friday. Isaacson appears to be betting on a recovery in lithium prices and improved fundamentals for the battery materials producer.

Applied Materials Gets the Biggest Target Hike

Susquehanna analyst Mehdi Hosseini delivered perhaps the most aggressive upgrade of the bunch, raising Applied Materials Inc (AMAT) from Neutral to Positive and more than doubling his price target from $180 to $400. The semiconductor equipment maker closed Friday at $301.18, but Hosseini clearly sees substantial room to run. The call likely reflects optimism about chip manufacturing investment cycles and AI-related equipment demand.

These upgrades span different sectors, from software and semiconductors to industrial components and specialty chemicals, suggesting analysts are finding pockets of opportunity across the market rather than concentrating bullish calls in any single area.
