Western Digital plunged 11.96% to $457.06 as part of a broader memory and storage sector selloff on Thursday, August 6, 2026. According to 247wallst.com, WDC shares slid alongside peers—SanDisk down 11% and Micron down 6%—in a coordinated memory selloff. Wall Street analysts also made dramatic moves on the stock Thursday, including double-digit price-target cuts on several high-profile names per 247wallst.com.
9:30 AM ETValuation✓ High confidence
Western Digital beat fiscal Q4 earnings expectations (adjusted EPS $3.56 vs. $3.31–$3.35 estimate; revenue $3.75B vs. $3.70B consensus) but shares fell 17.41% intraday as investors engaged in profit-taking after the stock's massive pre-earnings rally had already priced in near-perfection (per web_catalyst and finance.yahoo.com). The sell-the-news reaction reflected lofty prior gains and sector-wide memory/storage peer weakness.

What changed: Medline Inc. moved -3.90% intraday from $36.67 to $35.24. Medline Inc. (MDLN ) shares dropped over 12% following its Q2 2026 earnings report. The sell-off was driven by a 58% plunge in net income caused by a $336 million pre-tax loss from a major fire at its Tracy, California distribution center, alongside a $200 million cut to its full-year adjusted EBITDA guidance. Key Earnings Factors - Net Income Collapse: GAAP net income dropped 58.3% year-over-year to $139 million due to the distribution center fire costs, overshadowing an otherwise top-line revenue beat of $7.7 billion. - Lowered Guidance: Management slashed its full-year adjusted EBITDA outlook to a range of $3.3–$3.4 billion. - Headwinds: Investors reacted poorly to commentary regarding ongoing inflationary pressures, operational investments, and retail channel softness.

3:30 PM ETLATESTValuation✓ High confidence
SanDisk shares fell 5.54% to $1,275.67 as part of a broader memory and storage sector selloff. According to 247wallst.com, Western Digital sank 16% and Micron dropped 6% on the same day, with SanDisk initially down 11% in early trading—suggesting the decline reflects sector-wide weakness in NAND memory and storage stocks rather than company-specific news.
9:30 AM ETRisk✓ High confidence
SanDisk reported fiscal Q4 2026 earnings and revenue that beat Wall Street estimates, driven by strong AI-related memory demand, but the company issued cautious forward guidance that fell short of consensus expectations, triggering a sharp selloff. The stock declined 12.91% to $1176.16 as investors reacted negatively to the measured outlook despite the earnings beat, compounded by sector-wide concerns about the sustainability of AI capital spending by hyperscalers.
What's next
What to watch
SanDisk earnings scheduled for August 13, 2026 (consensus EPS $33.88); watch whether management guidance on NAND demand and AI-driven cloud growth supports or refutes the recent selloff narrative.

Fermi closed July 31 down 15.45% at $5.69, erasing the previous session's 14.85% gain — with no company announcement identified. The conditions around it were structural: sell-side targets cut roughly 60% in five weeks, 12.1 million new shares listed in London two days earlier, and a short base up a quarter in a month against a float of 288 million shares.

Why Micron (MU) Stock Fell 5.9% on July 31, 2026 — and Why Bullish Memory News Made It Worse
Micron opened higher and rose 6.4% intraday on July 31, 2026 after Amazon raised 2026 capex to $220 billion citing memory costs and Apple flagged a shortage — then closed down 5.90% at $823.03, near its low. The tape shows why: the S&P 500 and Nasdaq rose, the semiconductor index was flat, and hard-disk peers Western Digital and Seagate closed higher. Only DRAM and NAND names fell. The debate has moved from whether memory demand is real to when Micron's margins peak — and no analyst has cut a target through a 34% drawdown.

Why did Danaher (DHR) stock fall ~13% on July 21, 2026 — a beat-and-raise undone by a core revenue guidance cut
Danaher fell nearly 13% on July 21, 2026 despite beating on adjusted EPS and raising its full-year earnings guidance. The company tied that raise partly to completing the Masimo acquisition early — while cutting full-year core revenue growth guidance to 3–4% from 3–6% and marking bioprocessing down to mid-single-digit growth. The market paid for the organic line, not the inorganic one. Bioprocessing peers Repligen and Sartorius fell in sympathy while instrument makers rose, on a day the broad market was up ~1%.

Why did Hut 8 (HUT) stock jump ~11% on July 20, 2026 — a second $9.8 billion Beacon Point lease that fully commercializes a 1 GW campus
Hut 8 jumped about 11% on July 20, 2026 after a second 352 MW, 15-year, $9.8 billion lease fully commercialized its 1 GW Beacon Point campus in Texas — signed by the same unnamed tenant that took Phase 1 in May. The deeper significance is financing: Phase 1 was funded with $4.25 billion of non-recourse, Baa2-rated notes, and an anchor lease is the precondition for repeating that. But the move only round-trips a two-session drop, leaving the stock below where it closed on Wednesday.
