AI and chip stocks collapsed by $1.3 trillion on Friday, marking the semiconductor sector's worst day since 2020. The selloff followed a stronger-than-expected jobs report that rekindled recession fears and a disappointing outlook from Broadcom that spooked investors across the chip supply chain.

The market now splits into two camps. Bubble theorists point to the relentless AI rally that pushed valuations to historic levels without corresponding earnings growth. They argue the Friday drop signals the beginning of a sustained correction as reality catches up to hype. The sector's meteoric rise outpaced fundamentals, they contend, making a deeper unwind inevitable.

The profit-taking camp counters that volatility after extreme rallies is routine. Friday's drop follows months of gains that left many positions overbought. A hot jobs report and one disappointing guidance call, they argue, triggered natural rebalancing rather than a structural break in market confidence. Chip demand for AI infrastructure remains strong, and interest-rate concerns, while real, do not erase the sector's long-term tailwinds.

The data supports both views partially. Semiconductor stocks have rocketed 80 percent-plus in two years, far outpacing earnings growth. But order books for AI chips remain robust, and major foundries continue expanding capacity. Friday's magnitude matters less than what happens next. A quick bounce suggests profit-taking. A sustained decline below key support levels indicates deeper trouble.

The disagreement reflects genuine uncertainty about AI's maturation curve. If AI adoption accelerates as expected, current valuations look reasonable. If the hype cycle is peaking while returns lag investment, the selloff continues. Broadcom's guidance shift suggests at least some moderation in demand acceleration, a data point that tips scales toward caution for now.
