Stocks Tumble on Tech Stock Weakness and Higher Bond Yields

U.S. equity indexes slid with the S&P 500 down 0.86%, Nasdaq 100 off 1.85% and the Dow down 0.39% as a tech-led selloff — headed by Broadcom plunging more than 10% after a weak sales outlook and no 2026 AI revenue guide — outweighed rotation into industrials; Oracle’s and Broadcom’s disappointing outlooks have heightened doubts about the payoff from hefty AI infrastructure spending. Hawkish Fed commentary from regional presidents including Austan Goolsbee, Jeff Schmid and Beth Hammack lifted the 10‑year yield roughly 2–2.4bp to ~4.18% and trimmed odds of near‑term rate cuts (markets price ~24% chance of a 25bp cut in January), while Treasury curve steepening and the Fed’s announcement to buy up to $40bn/month of T‑bills are reshaping front-end liquidity. Q3 earnings season is essentially complete (496 of 500 S&P companies reported) with 83% beating and aggregate earnings up 14.6% y/y — the best quarter since 2021 — but near-term market direction remains driven by AI-capex uncertainty and tech valuation reassessment, with chip and AI-linked suppliers broadly weak and selective consumer and industrial beats (e.g., Lululemon, Quanex) outperforming.

Analysis

U.S. equity benchmarks slid with the S&P 500 down 0.86%, the Nasdaq 100 off 1.85% to a 1.5‑week low, and the Dow down 0.39%; Broadcom plunged more than 10% after a sales outlook disappointed and it declined to provide a 2026 AI revenue guide, triggering broad weakness across chip names (Micron -5%, Lam Research -4%, several others down 2–4%+). Rotation into industrials helped limit the Dow's decline, but the intra‑day move highlights renewed investor skepticism on the near‑term payoff from heavy AI infrastructure spending.

Hawkish commentary from Chicago Fed President Austan Goolsbee, Kansas City Fed President Jeff Schmid and Cleveland Fed President Beth Hammack pushed the 10‑year yield up roughly 2–2.4 basis points to about 4.18% and reduced market odds of a January rate cut to ~24%, reinforcing expectations for a modestly restrictive stance. The Fed's plan to buy up to $40 billion/month of T‑bills has steepened the yield curve, supporting front‑end liquidity while longer‑dated Treasuries remain under pressure amid inflation concerns.

Q3 reporting is essentially complete (496 of 500 S&P companies), with Bloomberg Intelligence noting 83% of reporters beat and aggregate earnings rising 14.6% y/y versus consensus +7.2%—the strongest quarter since 2021—yet market direction is now being driven by guidance risk and valuation repricing in AI‑linked sectors; Lululemon and Quanex outperformed after strong results, underscoring the current dispersion between selective consumer/industrial winners and tech suppliers under pressure.

Key Decisions for Investors

• Reduce or hedge direct exposure to AI‑capex dependent chip and equipment names (examples in the note: AVGO, MU, LRCX) after Broadcom's guidance miss, using options or size cuts to manage downside risk
• Consider reallocating a portion of risk to fundamentally beating names and defensive industrials that are supporting the Dow (e.g., LULU, NX, GE) while maintaining discipline on valuation
• Monitor Fed speakers and the 10‑year yield closely and limit duration exposure or favor shorter‑dated fixed income given curve steepening and lower odds of an imminent cut
• Use event‑driven hedges ahead of further corporate AI guidance and the Jan 27–28 FOMC meeting and be prepared to reprice technology positions if Broadcom/Oracle style guidance disappointments persist
