📊 Daily Gainers & Losers — Oct 16, 2026

📚 Past 3 days: 15 Oct · 14 Oct · 13 Oct

Broad Market: Brutal session for tech — Nasdaq -2.1% (-4.5% for the week, worst since June), S&P 500 -1.2%. Hot CPI (3.7% Sep), PPI surge (6.3% YoY), 10yr yield at 5.097%, and rising rate-hike bets triggered a risk-off rout. AI/neocloud debt fears (CoreWeave bond yields >15%) and China semiconductor competition (CXMT memory, DUV lithography) deepened the selloff. Only 2 of 83 watchlist tickers finished green.
