Western Digital

WDC dropped sharply during the regular session, closing 3.88% lower at $434.30, giving back all gains from a pre-market high of $469.70 (ET 08:48). The intraday low of $423.57 (ET 10:43) represented a decline of over 7% from the opening price of $455.23, as the memory chip sector broadly weakened. Despite Q4 2026 net profit surging 1053.43% YoY to $3.195 billion and revenue growing 43.84% YoY to $3.747 billion, analyst downgrades (including those noted in reports covering TSLA, NVDA, and BBBY) triggered profit-taking, pulling the stock well off its recent highs. The stock recovered slightly to $434.689 in after-hours trading. While the strong fundamentals—EPS of $8.21 and net profit margin of 85.27%—provide a floor, the near-term price action remains weak.

Western Digital (WDC.US) plunged as much as 18% during regular trading on August 6, despite a Q4 2026 earnings beat, as investors focused on disappointing guidance. Revenue of $3.747 billion grew 43.84% YoY, and net profit surged 1053.43% to $3.195 billion, yet the stock closed at $451.52, 43.55% below its 52-week high of $799.87 and well beneath both its 20-day MA ($518.89) and 60-day MA ($549.66). The session opened lower in pre-market at $429.02, hit an intraday low of $410.94, and recovered to $451.52 by the close, though post-market ticked down to $451. The sell-off was driven by broader memory-chip sector weakness, with SanDisk falling ~8% after-hours, amid valuation concerns, while year-to-date the stock still holds a 140.55% gain, providing a counterbalance to the day's negative momentum.

WDC dropped 4.9% in regular trading to close at $521.59, driven by pre-earnings sentiment reversal after a strong pre-market rally. The stock opened at $551.00, up from a pre-market surge fueled by overnight memory chip gains (Micron up over 7%), hit an intraday high of $563.39, then steadily declined to an intraday low of $521.59. Q3 2026 earnings showed revenue of $3.37B (+45.47% YoY), net profit of $3.17B (+529.82% YoY), and EPS of $8.20 (+482.92% YoY), with net margin at 96.04%. However, the stock closed below both the 20-day MA of $525.32 and the 60-day MA of $550.77, remaining 34.79% below its 52-week high of $799.87. Options market pricing implied a ±15% swing on earnings night, reflecting uncertainty about sustained memory demand, while post-market data offered no clear direction.

Western Digital opened higher today but pulled back sharply, last trading at $545.855 as of 09:32 ET, up ~3.5% from the prior close of $527.22, after hitting a pre-market high of $569.88. The initial surge was driven by a broad rebound in the memory chip sector, with Micron and SanDisk both rising in overnight trading. However, the stock gave back most of those gains shortly after the regular session opened, indicating strong selling pressure near the highs. The company's Q3 2026 earnings showed net profit surging 529.82% YoY to $3.168 billion, with EPS of $8.1964 and revenue up 45.47% YoY to $3.337 billion, reflecting solid fundamentals. Yet the stock still trades 31.76% below its 52-week high of $799.87 and below its 60-day MA of $550.035, highlighting ongoing tug-of-war between momentum and resistance. While post-market trading has seen the stock slip to $533.5, suggesting lingering caution.

WDC.US opened sharply lower and traded downward in a single direction on August 3, hitting $516.69 by 9:30 AM ET, down 5.2% from the prior close of $544.84, leading losses in the memory chip sector. Premarket weakness was already signaled, with the lows reaching $520.00, a decline of nearly 4.6%. Industrywide pressure was evident as Micron dropped nearly 3% and SanDisk fell nearly 2% in premarket. Despite strong fundamentals—Q3 2026 revenue up 45.5% YoY to $3.337 billion and net profit soaring 529.8% to $3.168 billion—the stock remains below its 20-day MA of $525.42 and 60-day MA of $548.49, and trades 35.4% below its 52-week high of $799.87. The stock has still gained 175.3% year-to-date, though, which may attract bargain hunters.
