Western Digital's stock soared 5.10% intraday on Monday, reflecting a strong positive move for the data storage company.

The rally is primarily attributed to sustained artificial intelligence infrastructure buildout, which is accelerating demand for the company's high-capacity enterprise hard disk drives and solid-state drives. Additionally, optimistic market expectations surrounding Western Digital's strategic plan to split its flash memory and hard drive business units have bolstered investor sentiment.

Further supporting the surge, multiple investment banks recently raised their price targets on the stock, signaling strong institutional conviction. Bullish options activity, including a significant out-of-the-money put sale, also points to investor confidence. The move aligns with a broader recovery in chip and storage stocks during the session.
