Just days after the S&P 500 set a record above 7,600, the market that had been driving Wall Street’s gains all year turned sharply against it. A semiconductor-led selloff erased roughly a trillion dollars in value, exposing how concentrated the rally had become and how quickly sentiment can reverse.
The trigger was a combination of disappointing reaction to chip earnings and a labor market that proved too strong for comfort. The Nasdaq fell about 4% as a semiconductor slide wiped roughly $1 trillion from markets, with the rout pressured by a pullback in the AI rally and weakness across chip shares. Micron fell 6.3%, Broadcom slipped 3.8%, Marvell lost 8%, and AMD dropped 6.3% in early trading, with Marvell sliding nearly 17% at one point as investors reassessed the sky-high expectations baked into the sector.
Counterintuitively, good economic news made things worse. The May jobs report showed 172,000 new jobs, roughly double the consensus forecast, while unemployment held at 4.3%, and the government revised up job gains for March and April. Stocks reacted poorly in a “good news is bad news” scenario, as stronger hiring pushed Treasury yields up and raised the odds of further rate increases rather than cuts. A resilient labor market, in an environment where inflation is already being aggravated by energy costs, reduces the case for the Federal Reserve to ease policy, which weighs on the richly valued growth stocks that dominate the indexes.
The sequence of events had been building for days. Technology was the only sector to experience a meaningful decline earlier in the week, as capital rotated into Health Care and Financials following Broadcom’s after-hours earnings. That rotation accelerated into the broader rout, suggesting investors weren’t fleeing the market entirely but repositioning away from the crowded AI-and-chips trade.
The episode is a reminder of the risk embedded in market concentration. When a handful of megacap technology and semiconductor names account for an outsized share of index gains, any wobble in that group can drag the whole market down. The same dynamic that powered records on the way up works in reverse on the way down.
For investors, the takeaway isn’t necessarily that the AI story is over but that expectations had run far ahead of the cushion for disappointment. Even strong results, as Broadcom’s reception showed, can trigger selling when a stock is priced for perfection. Whether this proves a healthy reset or the start of something deeper will depend heavily on the path of inflation, interest rates, and the next round of earnings.
