Watsco shares jump 5.92% after-hours as institutional investors boost holdings.

Watsco Inc. (WSO) surged 5.92% in after-hours trading, driven by recent institutional buying activity and a shift in analyst sentiment. Key news included Quantbot Technologies LP purchasing 3,071 shares and Comerica Bank acquiring a stake on August 28, 2025, signaling renewed institutional confidence. Additionally, brokerages maintained a "Hold" recommendation, with an average target price of $396.10, slightly below the current price, but recent purchases by entities like AlphaQuest LLC and B. Metzler AG suggest growing optimism. While Zacks Research issued a negative Q3 earnings forecast, the stock’s upward movement appears tied to accumulating institutional positions and positive market positioning, outweighing bearish estimates. The after-hours rally reflects investor anticipation of improved performance or strategic positioning ahead of earnings reports.
