After-RTH Summary — Monday, October 12, 2026
S&P 500 and Nasdaq slipped on a tech and optical/memory selloff while the Dow notched a gain on rotation into value, as oil pushed higher into a heavy bank-earnings and CPI week.
Index Closes
S&P 500 (SPX): 7,807.24, -4.30 pts (-0.06%)
Nasdaq 100 (NDX): ~30,690, -0.8%
Nasdaq Composite (COMP): 27,245.90, -120.27 pts (-0.44%)
Dow Jones (DJI): 51,850.55, +195.60 pts (+0.38%)
Russell 2000 (RTY): 2,794.48, -0.4%
The S&P spent the session in the red and only found buyers late, finishing a hair below Friday's 7,811.54 and still within reach of last week's record. The Dow was the lone major gainer as money rotated out of large-cap tech into industrials and value. Bond markets were closed for the holiday, so there was no fresh Treasury print; the 10-year sat near 5.24% intraday.
Sector Heatmap
Winners
Industrials: led the Dow higher on the rotation bid
Communication services: early leader, helped by Meta (+3.4%), Snap (+4.8%) and Comcast (+4.1%)
Consumer/internet: Shopify (+5.1%) and eBay (+4%, Morgan Stanley top pick) bid
Losers
Technology / semiconductors: memory and optical names hit hardest
Utilities: soft alongside tech in the morning tape
Rotation, not risk-off: VIX hovered near 15 while leadership shifted from AI hardware into cyclicals and value. Sector-level percentage closes were not yet published at the time of writing, so the heatmap above is directional.
Notable Movers / Themes
Optical and memory flush: Ciena (-10.5%), Lumentum (-9.8%) and Applied Optoelectronics (-8.1%) led decliners; Micron and SK Hynix fell 3%+ after China's CXMT touted a new memory-cell design.
Analyst calls: Salesforce +4.3% on a double upgrade; Adobe -4% on a double downgrade.
M&A chatter: CCC Intelligent Solutions jumped ~10% on buyout reports; Chipotle fell 4%+ after Starbucks denied it is buying the company.
High-beta pain: IonQ (-9.3%) and Lucid (-9.2%) among the worst large decliners.
Energy and geopolitics: Brent ran to ~$106.65 (+1.8%) on Russian strikes on Ukrainian energy sites and Middle East tanker attacks; WTI ~$93. Gold slipped ~0.5% to ~$4,193.
After-Hours Earnings & News
C3.ai (AI): -6.6% after hours, giving back a morning pop of roughly 10%.
Dollar: firmer, with USD/JPY at a 2.5-week high near 158.64.
Key Levels for Tomorrow's Open
SPX: 7,800 pivot. Hold it and the 7,811 Friday close is the first reclaim; lose it and the tape is leaning on tech weakness.
NDX: 30,700 area. Failure to reclaim keeps the optical/memory unwind in control.
DJI: 51,850 / 52,000. Rotation bid needs follow-through above 52,000.
RTY: 2,800. Small caps closed just under; a reclaim signals breadth is intact.
Macro Context Going Into Tuesday
Earnings season kicks off in earnest Tuesday with JPMorgan and Citigroup (Goldman and Wells Fargo also due this week), with banks having lagged in recent weeks, so reactions will set the financials tone. September CPI lands Wednesday and PPI Thursday, with retail sales also on deck, all against 5%+ long yields, $90+ crude and headline risk around the Strait of Hormuz and Red Sea. Expect positioning to stay tight ahead of the inflation prints.
