Western Digital (NASDAQ:WDC) ended the trading week on a down note Friday, with shares sliding 6.9% to $519.80. Despite the late-week reversal, the stock still managed to post a solid 8.9% weekly gain, outperforming the S&P 500 by roughly 9.5 percentage points. The broader index edged 0.6% lower over the same period.
Earnings Outlook Brightens
While the stock price retreated, the company's earnings outlook continued to improve. The consensus estimate for fiscal fourth-quarter profit has climbed 20% over the past three months to $3.30 per share. That figure now sits five cents above management's own midpoint guidance of $3.25 per share, signaling that investors expect the company to deliver more than just a simple guidance match when it reports on August 5.
Friday's close stood 35% below the June 18 intraday high of $799.87, a reminder of the stock's volatility. However, the selloff came on relatively light volume of 4.8 million shares, about 43% below the 65-day average, suggesting the move lacked conviction.
Seagate Results in Focus
Seagate Technology (NASDAQ:STX) will report its fiscal fourth-quarter results on Tuesday, providing a key read-through for the hard-drive industry. Seagate has guided for revenue of $3.45 billion and adjusted earnings of $5.00 per share. Investors will be closely watching for commentary on pricing, cloud demand, and capacity trends, which will have direct implications for Western Digital.
Both large hard-drive makers have been riding a wave of AI-driven demand for data storage. Irving Tan, Western Digital's chief executive, recently emphasized that AI data must be "stored persistently and cost-efficiently on HDDs." The company separated its flash business in 2025, leaving it with a more direct hard-drive exposure.
Strong Operating Base
Western Digital's own operating fundamentals remain robust. In the fiscal third quarter, revenue surged 45% year-over-year to $3.34 billion. Adjusted gross margin reached 50.5%, while adjusted earnings came in at $2.72 per share. Management's fourth-quarter midpoint calls for $3.65 billion in revenue, a 51.5% adjusted gross margin, and $3.25 in earnings. Those figures imply 9.4% sequential revenue growth, a one-percentage-point margin increase, and 19.5% earnings growth.
The Tuesday surge in both Western Digital and Seagate came during a 5.2% rebound in the semiconductor index, but by Friday the chip index had fallen more than 4%. Lindsey Bell, chief investment strategist at 248 Ventures, attributed the earlier rally to fear of missing out, warning that the stocks were "priced for perfection."
Risks and Outlook
Broader risks remain elevated. The Federal Reserve meets this week, and a dense technology earnings calendar could add to market volatility. A weaker-than-expected Seagate outlook could reverse Western Digital's weekly gain. Other material risks include tariffs, supplier concentration, demand swings, and competitive pricing.
For now, the near-term question is validation. Earnings estimates are still rising, but Friday's price action showed how quickly investor conviction can break. All eyes are on Seagate's report Tuesday for the next directional signal.
