Chip Stocks Slide as Institutions Rotate Out of Tech and Broadcom Hangover Lingers

US semiconductor stocks fell in Tuesday’s session, June 16, 2026, as a combination of institutional repositioning, post-earnings fallout, and profit-taking sends the sector broadly lower.

Intel and Marvell Technology are leading the declines down 7% and 7.3%, respectively, while AMD is off 5.9%, and Micron is giving back 5.1% of Monday’s 8–11% surge.

Broadcom is slipping a further 3.6%, and even Nvidia — the sector’s bellwether — is down 1.75%. The Technology Select Sector SPDR Fund (XLK) has fallen 1.87%, confirming that selling pressure is sector-wide rather than stock-specific.

The catalyst that set off the broader sector malaise traces back to Broadcom’s June 3 earnings, where despite reporting 48% revenue growth and a staggering 143% jump in AI chip sales, the company’s forward AI guidance disappointed investors expecting even more. The stock has now lost more than 20% from its all-time high near $500, and the aftershocks have kept the whole sector on the back foot.

Tuesday’s fresh trigger came from Swiss private bank Lombard Odier, which announced it was downgrading its view on global technology stocks from overweight to neutral, citing stretched year-to-date gains and a fading earnings upgrade cycle. The move has prompted fund managers to trim tech exposure across the board.

The rotation appears deliberate: financials and industrials are gaining over 1% each, suggesting investors are actively reallocating capital rather than simply de-risking.

Despite the turbulence, the fundamental AI demand story remains intact. Micron’s high-bandwidth memory capacity is reportedly sold out through end-2026, and Nvidia recently raised $25 billion in bond markets on extraordinary demand. Analysts say this looks less like a trend reversal and more like a valuation reset in a sector that had simply run too far, too fast.
