Top 5 Losers
- 🔴 STX (Memory) -4.19% — $771.81 — Memory/storage complex extended its slide on profit-taking after a huge YTD run plus capacity concerns; 5% Treasury yields pressured the rate-sensitive group
- 🔴 SNPS (EDA) -3.60% — $367.70 — EDA group de-rated on lingering China export-control and domestic EDA competition worries; no fresh company-specific news
- 🔴 WDC (Memory) -3.51% — $411.96 — Sympathy selling in the memory/storage rout alongside STX/MU/SNDK after a roughly 250% run-up in 2026
- 🔴 MKSI (Semi Equipment) -3.25% — $231.50 — AI-capex sustainability fears and rising rates hit semi equipment; still digesting a post-earnings de-rating (-14% since the late-Aug print)
- 🔴 ORCL (Big Tech / Platforms) -3.07% — $140.35 — Fell as Larry Ellison scrapped his plan to sell up to $7.5B of stock; 10-yr yield above 5% and Fed rate-hike bets weighed on high-capex AI names
*Data verified: all 84/84 rows timestamped 2026-09-15 (ET regular close ~20:00 UTC) — single clean session; 39 up / 45 down / 0 flat. Risk-off tape as the 10-year Treasury broke above 5% (highest since 2007) with Fed rate-hike bets rising and oil near $104–108 on Middle East tensions; long-duration tech (ORCL, NFLX, ADBE, SMCI) and memory (STX, WDC) led lower. The standout bid was mobile/RF — SWKS, QRVO and QCOM averaged +9.0% on the Skyworks–Qorvo merger breakthrough and QCOM's AWS AI-inference partnership — plus day-two cybersecurity strength (CRWD).
