Broadcom (NASDAQ: AVGO) delivered disappointing revenue guidance that sent shockwaves through technology markets on Thursday, prompting investors to reassess the pace of AI demand growth.

The artificial intelligence rally lost significant momentum during the session, with AVGO shares falling sharply by 12.59% following the underwhelming forward-looking figures.

Investors had come to expect strong, accelerating demand projections from semiconductor and AI-adjacent firms, making Broadcom’s cautious outlook particularly jarring for market participants.

The broader S&P 500 managed to hold its ground despite the tech sector turbulence, closing the session up 0.41% as other market segments picked up the slack.

Healthcare stocks proved resilient throughout the trading day, offering a degree of stability that contrasted sharply with the volatility seen in the technology space.

Financial stocks also posted a solid performance, reinforcing the view that market strength is becoming less concentrated in the AI trade and more broadly distributed.

Marvell Technology (NASDAQ: MRVL) bucked the negative trend in semiconductors, gaining 4.90% and standing out as one of the few bright spots in an otherwise difficult day for tech.

Micron Technology (NASDAQ: MU) was not as fortunate, declining 7.74% as investors grew more cautious about near-term demand trajectories across the chip sector.

Super Micro Computer (NASDAQ: SMCI) also saw pressure, slipping 1.10% as broader sentiment around AI infrastructure spending softened in the wake of Broadcom’s comments.

Quantum computing firm Quantinuum attracted attention during the session, adding a speculative dimension to a market day that was otherwise dominated by semiconductor earnings fallout.

The day’s market action raises broader questions about whether the AI investment cycle is entering a more selective phase, where only the strongest catalysts will drive outsized gains.

Investors appear to be recalibrating their expectations, demanding clearer evidence of monetization and revenue conversion before rewarding AI-linked companies with premium valuations.
