Western Digital (WDC) shares fell 18.24% to $424.48 on Thursday amid a sharp selloff in the memory chip sector. The decline followed a mixed earnings report and a broader sell-off in AI-related stocks. Analysts and traders pointed to weak sales guidance from Western Digital and its peer Seagate Technology as a key driver of the market’s pessimism.
What Happened
Western Digital reported Q4 revenue of $3.75 billion, exceeding the $3.68 billion estimate, with adjusted EPS of $3.56, above the $3.31 forecast. However, the company guided for Q1 revenue of $4.00 billion to $4.20 billion, below the $4.02 billion consensus. The stock opened with a 15.4% gap down from the previous close of $519.17, and continued to fall throughout the morning session. The decline came as broader market sentiment soured on memory and AI stocks, with SanDisk also reporting weak guidance and falling nearly 10% in early trading. UBS cut its price target for Western Digital to $525, citing valuation concerns. Meanwhile, VanEck’s Nicholas Frasse downplayed the volatility, calling it a reversion to the mean in the chip sector.
What The Data Shows
The stock has moved 4.3% higher over the last eight sessions, reaching $519.17 before Thursday’s drop. The current session saw a volume of 2.3 million shares, which is 0.3 times the 3-month average. Insider transactions over the last 90 days include 11 sales totaling $11.6 million, with no insider purchases. Congressional trades show three buys by Donald J. Trump in March, but no recent sales. The stock’s 52-week range is $73.14 to $799.87, and it trades at a P/E of 28.4 with a beta of 2.22. Retail traders on r/wallstreetbets noted the stock’s earnings beat but highlighted the late-session selloff as a sign of broader sector weakness.
What To Watch
Western Digital has no scheduled earnings in the near term, but coverage breadth and sentiment will be key to monitor. Analysts will be watching for further guidance on demand trends and how the broader AI and memory sectors respond to earnings updates.
