Today At A Glance:

Stocks fell broadly, led by a renewed sell-off in big tech and AI winners after weak private layoff data and ongoing shutdown/tariff noise kept uncertainty high. The Nasdaq lagged hardest; semis and high-multiple software took the brunt, though one standout (Datadog) bucked the trend on a strong outlook. Consumer names were mixed as DoorDash cratered on heavier 2026 spend plans and CarMax plunged on a CEO exit and weak prelims. Defensive pockets held up better, and a few industrial/health-care names rallied on earnings. By the close all three majors were lower, with breadth negative and volatility ticking up.

Today’s Index Performance:

• Dow Jones Industrial Average — The Dow opened today at 47,255.12 and closed today at 46,913.65, with the percentage change of −0.84%.
• S&P 500 — The S&P 500 opened today at 6,787.59 and closed today at 6,720.39, with the percentage change of −1.12%.
• Nasdaq Composite — The Nasdaq opened today at 23,461.29 and closed today at 23,053.99, with the percentage change of −1.90%.

Gainers Of Note:

• Datadog (NASDAQ: DDOG) — Cloud observability & security; spiked ~20%+ after guiding Q4 revenue and EPS above consensus, citing demand from AI-driven security workloads.
• Snap (NYSE: SNAP) — Social media; jumped ~18% on narrowing losses and a new $400M AI partnership with Perplexity, putting the name on “most-moved” lists.
• Air Products & Chemicals (NYSE: APD) — Industrial gases; rose ~9–10% as investors cheered a strategic reset alongside Q4 results broadly in line with expectations.

Losers Of Note:

• DoorDash (NASDAQ: DASH) — Delivery platforms; tumbled ~16–18% after a profit miss and plans to boost 2026 investment by “several hundred million,” stoking margin fears.
• CarMax (NYSE: KMX) — Used-auto retail; plunged on a surprise CEO departure and soft preliminary Q3 metrics implying weaker comps and profits.
• Duolingo (NASDAQ: DUOL) — Language-learning app; fell ~20–25% despite beats, as Q4 bookings guidance underwhelmed and management prioritized user growth over near-term monetization.

Active Traders Of Note:

• Nvidia (NASDAQ: NVDA) — AI semis; heavy volume amid the tech drawdown as traders rotated out of the year’s biggest winners. (Most-active board showed NVDA at ~216M shares.)
• Tesla (NASDAQ: TSLA) — EVs/AI; brisk turnover (~101M shares) as risk-off pressure hit high-beta growth.
• AMD (NASDAQ: AMD) — Semiconductors; active (~60M shares) as chip momentum cooled alongside broader AI sentiment.

Looking Forward:

With AI-heavy tech wobbling, near-term tone hinges on whether earnings guidance can offset valuation jitters and patchy macro signals. Watch for additional tariff/shutdown headlines and any fresh Fed rhetoric to sway rate-sensitives and the dollar. If dip-buyers show up in semis/software, Friday could see a reflex bounce; otherwise expect defensives/quality to keep a relative bid.
