    Broadcom Q3: revenue +85% and AI semiconductor revenue +221% to $16.7B; stock fell ~3%

    Question

    Broadcom Q3: revenue +85% and AI semiconductor revenue +221% to $16.7B; stock fell ~3%

    Direct answer

    Zacks Investment Research reported Broadcom delivered 85% revenue growth in Q3 and AI semiconductor revenue up 221% to $16.7 billion. Despite the strong underlying numbers, Broadcom's stock fell nearly 3% after management's Q4 guidance was considered slightly below some Wall Street forecasts. The mechanics run through relative performance in AVGO, influencing SMH and broader tech indexes because Broadcom is a large semiconductor bellwether. Guidance-driven downside in AVGO can widen sector dispersion and lift implied volatility in semiconductors. Monitors include AVGO price follow-through, SMH intraday performance, and changes in analyst guidance revisions over the next week.
