Western Digital Corporation (NASDAQ: WDC) saw its shares rally sharply on Monday, leading the S&P 500 as investor enthusiasm for AI-related storage plays intensified. The stock closed at $653.53, up 16.10% for the session, after touching an intraday high of $658.80. The move added billions to the company's market capitalization, which now stands at approximately $225 billion, according to Google Finance. The stock's price-to-earnings ratio sits at 39.03, reflecting the premium investors are willing to pay for anticipated future growth.
Morgan Stanley's Bullish Call
The catalyst for Monday's surge was a fresh note from Morgan Stanley analyst Erik Woodring, who raised his price target on Western Digital to $650 from $488 while maintaining an Overweight rating. Woodring cited robust demand for nearline enterprise storage, accelerating pricing trends, expanding margins, and improved operating leverage as key drivers. Nearline enterprise storage refers to high-capacity hard disk drives (HDDs) used by cloud and data-center operators for data that needs to be readily accessible but not on the fastest tier of storage. The analyst also boosted his earnings per share estimates for fiscal 2027 and 2028 to $22.40 and $43.47, respectively.
AI Fueling HDD Demand
Pricing power remains a critical factor for Western Digital's outlook. HDDs continue to play a vital role in storing vast amounts of cloud and AI data at a lower cost compared to solid-state drives (SSDs). Morgan Stanley expects HDD demand to grow by 40% to 50% annually, outpacing supply growth of 30% to 35%, which should keep the market tight and support pricing. Meanwhile, rising NAND flash prices—the memory used in SSDs—could further encourage customers to opt for HDDs for large-scale storage needs, according to a report from MarketWatch.
Recent Financial Performance
Western Digital's recent results provide a solid foundation for the bullish thesis. In its fiscal third quarter, reported on April 30, the company posted revenue of $3.34 billion, a 45% year-over-year increase. Non-GAAP gross margin came in at 50.5%, while non-GAAP diluted earnings per share reached $2.72. Chief Executive Officer Irving Tan noted that every AI workload generates data that is stored persistently and cost-efficiently on HDDs, underscoring the company's strategic positioning in the AI ecosystem.
Valuation Risks and Market Context
Despite the strong rally, Western Digital's stock now trades near its 52-week high of $658.80 and well above its 52-week low of $56.26. The average 12-month analyst price target from Google Finance stands at $565.94, which is below Monday's closing price. Out of 16 analysts covering the stock, 14 rate it a Buy, 2 rate it a Hold, and none recommend selling. This disconnect between the current price and the average target highlights the valuation risk: if HDD prices weaken, AI storage orders decelerate, or margins fall short of expectations, the stock's recent momentum could reverse sharply.
What Investors Are Watching Now
Market participants are now focused on Western Digital's fiscal fourth-quarter results, which are expected to be released in the coming weeks. The company's previous guidance called for revenue of $3.65 billion, plus or minus $100 million, with non-GAAP gross margin between 51% and 52% and non-GAAP EPS of $3.25, plus or minus $0.15. Investors will be looking for confirmation that AI-driven HDD demand and pricing power can sustain the rally. For those betting that the AI storage shortage will persist and support higher HDD prices, Western Digital remains an intriguing but high-risk play. After Monday's surge, the shares appear expensive, and stepping in now carries significant downside risk.
