Memory Chip Stocks Tumble: Broadcom, Intel Lead Selloff

Semiconductor Stocks Rout: What Happened?

Memory chip stocks dropped sharply on June 4, kicking off a broad selloff that ripped through the semiconductor sector. The declines were not confined to a single name. From custom AI chip designers to memory specialists, the red ink spread fast. By the closing bell, every major chip stock was nursing losses except one outlier.

The catalyst was not a macroeconomic shock or a trade war flare-up. It was a single earnings report — one that, on the surface, didn’t look terrible. But for a market that had been pricing in perfection, “not terrible” meant “not good enough.” Investors who had ridden the sector to record highs suddenly reached for the exit.

The chip sector downturn was a classic case of elevated expectations running headlong into reality. After a rally that added trillions of dollars in market value, the bar for positive surprises had been set impossibly high. When Broadcom’s AI revenue guidance landed slightly below the whispered numbers, the bull case unraveled — not because the business is crumbling, but because the stock price had sprinted too far ahead of what even strong earnings could justify.

Broadcom’s Earnings Miss Sparks Sector-Wide Selloff

Broadcom, a company that designs and makes custom artificial intelligence chips for other technology giants, reported quarterly results that, by any normal standard, were healthy. Yet its AI-specific revenue outlook came in below the most optimistic forecasts, and management simply reiterated full-year guidance instead of raising it. That was enough to send the stock down 12% in a single session.

The disappointment had a domino effect. Investors started asking whether the AI gold rush might be hitting a plateau. If Broadcom — a key supplier for companies like Google — is seeing a softer ramp in AI chip orders, what does that mean for the entire semiconductor food chain? Traders didn’t wait for answers; they sold first.

John Vinh, an equity research analyst at KeyBanc Capital Markets, pointed out that Broadcom has suffered some loss of business at its largest customer, Google, which has begun diversifying toward other chip suppliers. “The near-term pullback makes sense,” Vinh told CNBC, though he remained optimistic on Broadcom’s longer-term prospects. Keith Lerner, chief market strategist at Truist Wealth, struck a similarly measured tone, noting that “we’re due for a rest” after a powerful run. He added, “Bull market still deserves the benefit of the doubt, but often markets are two steps forward, one step back. We’ve had three steps forward, so maybe at least a mini step back, or at least some sideways chop.”

The selling wasn’t limited to Broadcom. The iShares Semiconductor ETF (SOXX) tracked toward its worst day in roughly two months. The Roundhill Memory ETF (ticker DRAM), a barometer for the memory market stocks, slumped 6%, on pace for its second-worst day ever.

Semiconductor Memory Stocks Take the Brunt

While the pain was widespread, semiconductor memory stocks absorbed an outsized share of the damage. Micron Technology, one of the world’s largest makers of DRAM (the fast memory computers use for active tasks) and NAND flash (the storage memory inside solid-state drives), fell more than 7%. SanDisk, the storage giant that had been the best-performing stock in the S&P 500 for 2026, gyrated wildly before closing down about 1%. Earlier in the week, SanDisk had already suffered a 5% drop, only to rebound the next day — a sign of just how jumpy the memory market stocks have become.

We detailed the earlier volatility in our recent analysis of SanDisk’s wild trading swings. That report noted how quickly a stock with blowout earnings and stellar guidance could reverse course when broad sentiment turned. Today’s action reinforces the pattern: strong fundamentals are guarding the floor, but sky-high valuations keep the ceiling fragile.

SanDisk’s recent numbers would be the envy of almost any other sector. In the second quarter, the company reported revenue of $3 billion and earnings per share of $6.20, both well above expectations. Third-quarter guidance called for revenue between $4.4 billion and $4.8 billion, with gross margins in the 65% to 67% range. The stock price, which had peaked at a 52-week high of $725, stood at $599 as of early March before the latest swings. Those are extraordinary figures — yet the market’s appetite for memory chips is currently driven less by the current numbers than by anxiety over what comes next.

The NAND DRAM stocks decline reflects deeper worries about the cyclical nature of memory pricing. NAND and DRAM are classic boom-and-bust products. When demand surges — as it has during the AI infrastructure buildout — prices spike and manufacturers thrive. But supply eventually catches up, and prices can crater. Short-sellers have recently re-ignited the debate, arguing that NAND pricing may be peaking even as supply shortages persist today.

Valuation Fears and the AI Bubble Debate

This selloff doesn’t exist in a vacuum. It lands squarely in the middle of a noisy, increasingly urgent conversation about whether the chip rally has entered bubble territory. Profit expectations for memory chip makers have been climbing at a breathtaking pace — in some cases projected to surge fifteenfold — pushing price-to-earnings ratios toward levels not seen since the 2008 financial crisis. A P/E ratio of 71 times, even for a high-growth sector, forces investors to ask how much future prosperity is already baked in.

As we explored in our analysis of the escalating AI bubble debate, Nvidia’s market capitalization has ballooned to $5.5 trillion, and the world’s largest hyperscalers are pouring an estimated $725 billion into data-center expansion in 2026 alone. Yet prominent skeptics are betting against the euphoria. Michael Burry, the investor known for shorting the mortgage market before the 2008 crash, has taken a $1.1 billion put option position betting that AI stocks are overheated. The International Monetary Fund and Bridgewater Associates have separately warned about overheating risks in the private credit fueling the AI boom.

The selloff in Broadcom and memory names can be read as the market collectively leaning toward the skeptics for a moment — or at least deciding that the risk-reward balance has shifted. Even if the AI buildout continues, the gap between reality and the price tag on some stocks may have simply grown too wide to ignore.

Analyst Perspectives and Price Target Revisions

Not everyone is running for the hills. Some Wall Street analysts have used the weakness to raise price targets, signaling confidence that the long-term story remains intact. Morgan Stanley boosted its price target on SanDisk from $1,100 to $1,750, arguing that memory demand is structurally higher and that the company’s shift toward multiyear supply agreements with customers will smooth out revenue volatility. That target implies significant upside even from the recent peaks.

KeyBanc’s Vinh maintained a constructive view on Broadcom despite the post-earnings slide. He acknowledged that near-term headwinds from Google’s supplier diversification are real, but he believes Broadcom’s diversified chip portfolio and custom AI pipeline will ultimately reward patience. Truist’s Lerner argued that “fundamentals are solid” and that a pullback after a historic run is not a reason to panic.

Other chip names illustrate the mixed picture. Marvell Technology, another custom chip player, initially dropped on Thursday but reversed course to close nearly 5% higher, suggesting that buyers are still selectively stepping in where they see value. Intel, which has been struggling with its own turnaround story, dipped only about 1%, while AMD slid 3% — bad days, but not the kind of damage that signals a sector-wide collapse. Still, the speed and breadth of the selloff served as a reminder that in today’s chip market, sentiment can turn on a dime.

Conclusion

Memory chip stocks dropped today because investors’ expectations finally caught up with an overheated market. Broadcom’s unremarkable guidance was not a disaster for the business, but it was enough to prick the balloon of near-perfection that had inflated stock prices across the semiconductor industry. The hardest-hit names — Micron, SanDisk, and other memory specialists — are caught between two powerful forces: genuinely strong demand driven by AI, and a gnawing fear that the cycle is peaking.

The market is not saying that the AI boom is over. Hyperscalers continue to spend, data centers are still being built, and memory-chip shortages remain a fact of life. What the market is saying is that some stock prices had simply raced ahead of reality, and that a breather was overdue. That doesn’t make the selloff easy to stomach, but it does make it logical — even healthy — in the context of a long bull run.

For anyone watching the sector, the lesson is not that chips are a bad bet. It’s that in a market as volatile as this one, the gap between what companies are actually earning and what investors are willing to pay can close suddenly and painfully. The coming weeks will show whether this selloff was a fleeting reset or the start of a deeper reassessment. For now, the semiconductor sector is learning — once again — that gravity still applies.
