Chip Stocks Roar Back After SOX's 10% Drubbing — Lam, Intel, Micron All Post Double-Digit Gains
After the Philadelphia Semiconductor Index shed roughly 10% the prior week on Broadcom's underwhelming AI guidance, chip stocks staged a broad-based rally on June 11 — Lam Research surged ~12.7%, Micron ~11%, Intel 10%-plus, and AMD ~8%.
Bottom line: After the Philadelphia Semiconductor Index (SOX) tumbled roughly 10% the prior week — triggered by Broadcom's (AVGO) cautious AI guidance — chip stocks staged a broad-based comeback on June 11, with Micron, Intel, Lam Research, and others posting double-digit or near-double-digit gains.
- SOX fell roughly 10% on June 6, dragging the entire sector lower.
- June 11 rebound: Micron (MU) up ~11%, AMD up ~8%.
- Lam Research (LRCX) up ~12.7%, Intel (INTC) up more than 10%.
- Nvidia (NVDA), the sector bellwether, posted a comparatively modest gain on the day.
- The selloff was sparked by Broadcom's post-earnings AI guidance miss, compounded by concerns over memory supply-demand and global smartphone demand.
- Several institutions attributed the bounce to a recovery in confidence around AI infrastructure spending.
After a brutal week of selling, semiconductor stocks bounced back sharply on June 11. According to TheStreet and several institutional recaps, chip names rallied broadly that day, with multiple stocks posting double-digit or near-double-digit gains — recovering a portion of the losses triggered by Broadcom's (AVGO) earnings guidance[TheStreet]. The whipsaw move underscores just how divided the market remains on the durability of AI demand.
What Hit Chip Stocks the Prior Week
To understand the June 11 rebound, you need to start with the preceding selloff. The Philadelphia Semiconductor Index (SOX) had fallen roughly 10% — triggering a broad sector-wide pullback[Money Morning].
The catalyst was Broadcom's post-earnings guidance. Broadcom posted record revenue, but its outlook for AI-related business fell short of the market's already-elevated expectations — and that disappointed investors. Concerns about memory chip supply-demand dynamics and weakening global smartphone demand piled on. Worth noting: Broadcom's underlying business kept growing; the stock's retreat reflected a guidance miss relative to high expectations, not a fundamental deterioration.
June 11 Rebound: Stock by Stock
Per TheStreet and related reporting, here's how chip stocks moved on June 11:
- Micron (MU) up ~11%;
- AMD up ~8%;
- Lam Research (LRCX) up ~12.7%;
- Intel (INTC) up more than 10%[TheStreet].
Nvidia (NVDA), the sector's flagship name, also closed higher on the day — but its gain was notably smaller than those of the stocks that had sold off more sharply beforehand. The pattern was classic oversold-bounce mechanics: names like Intel and Micron, which had been hit hardest, rebounded the most, while Nvidia's more modest move reflected valuation recovery rather than any change in fundamentals.
What Drove the Bounce
Different institutions landed on similar explanations. The primary driver, according to reports, was a restoration of confidence in AI infrastructure spending — with hyperscaler capex commitments for 2026 cited as evidence that demand for AI compute remains intact[heygotrade].
Several analysts also argued the prior week's selloff had simply gone too far. A Money Morning piece put it bluntly — headlined "Wall Street Sold Chip Stocks in a Panic. That Was a Mistake." — arguing the fundamentals hadn't deteriorated anywhere near enough to justify the magnitude of the drop[Money Morning]. That said, these are institutional views, not settled conclusions. A sector that drops 10% and then bounces sharply within a single week is a sector where real disagreement exists.
Will the Volatility Persist?
The sector's extreme swings are partly a function of where valuations sit. AMD, for instance, had gained more than 130% year-to-date through early June, trading at a forward P/E of roughly 84x — pricing in substantial future growth[Money Morning]. At those multiples, even marginal shifts in AI demand expectations can produce outsized price moves in either direction.
The signals worth watching: what major chipmakers say about AI and data center demand going forward, whether hyperscaler capex commitments actually translate into spending, and how cyclical segments like memory and smartphones evolve. Those factors will determine whether this bounce marks the start of a durable recovery — or just another swing in a high-volatility holding pattern.
