The semiconductor sector experienced its worst day in over two weeks, with the Philadelphia Semiconductor Index (SOX) dropping as much as 6% intraday before closing down roughly 2%.
The immediate catalyst for the sell-off was a weaker-than-expected sales forecast for artificial intelligence (AI) chips from industry giant Broadcom (AVGO), which triggered a nearly 13% plunge in its stock, marking its largest single-day decline since early 2025.
Despite the sharp market decline, some traders view the sell-off as a potential short-term correction.
The Domino Effect: From Broadcom's Avalanche to an AI Chip Sector Slide
The trigger was Broadcom's third-quarter AI chip revenue guidance falling short of market expectations.
The company projected AI semiconductor revenue of approximately $16 billion for the third quarter of its 2026 fiscal year, representing over 200% year-over-year growth, yet below the analyst consensus of $17.2 billion, with some buyers holding even more optimistic forecasts.
It also maintained its full-year 2026 fiscal year AI chip revenue guidance of about $56 billion, also lower than the average analyst expectation of $57.6 billion.
More significantly, Broadcom kept its AI chip revenue forecast for the 2027 fiscal year at "over $100 billion," rather than raising it substantially as the market had hoped, while its second-quarter infrastructure software revenue of $7.18 billion also slightly missed the $7.32 billion expectation.
The root cause lies in excessively high market expectations.
By Wednesday's close, Broadcom's stock had surged over 65% from its early April low and was up nearly 40% year-to-date.
In just the five trading days before the earnings report, driven by AI optimism alone, Broadcom's market capitalization increased by approximately $270 billion.
The options market had priced in a single-day move of about 7.8% ahead of the report, higher than the historical average.
In this context, the market was not anticipating merely "beating expectations," but a massive, blowout-level beat.
Some analysts noted that the primary reason for Broadcom's sharp decline was not weak earnings themselves, but the fact that prior expectations were already extremely elevated; any guidance that fell short of a massive beat could trigger profit-taking.
As a major semiconductor bellwether, Broadcom's plunge quickly sparked short-term concerns about whether the AI boom was cooling, dragging down the entire chip sector.
The Philadelphia Semiconductor Index plummeted as much as 6% during the session, ultimately closing down 2.15% at 13,617.50 points.
However, market capital did not exit the stock market but rotated into Dow Jones components like financials and consumer staples, contributing to a strong rebound of 874 points in the Dow Jones Industrial Average to a fresh record high.
On an individual stock level, Micron Technology fell nearly 8%, dropping below the $1,000 mark; ARM declined over 8%; Advanced Micro Devices (AMD) dropped more than 7%; Qualcomm fell over 4%; Intel declined more than 3%; Nvidia's stock price dipped nearly 0.8% at one point before recovering somewhat.
Optical communication stocks were also not spared, with Ciena tumbling nearly 16% post-earnings, POET down nearly 7%, Lumentum falling close to 6%, and Marvell Technology declining over 5%.
It is noteworthy, however, that not all tech stocks suffered in the storm.
Google bucked the trend, rising 3.82% to $369.27, Taiwan Semiconductor Manufacturing (TSM) ADRs gained 1.88% to $444.92, and Nvidia also rebounded to close up 1.82% at $218.66, indicating that the long-term demand logic for AI infrastructure remains recognized by the market, even if sentiment requires short-term digestion.
The reason Taiwan Semiconductor Manufacturing's ADRs "closed in the green" is twofold: firstly, its status as the global "sole node" is difficult to challenge—whether it's Broadcom's ASICs, Nvidia's GPUs, or AMD's chips, they all ultimately rely on TSM's advanced manufacturing processes.
Secondly, a "tech hardware-to-software ratio" indicator had previously sounded an alarm: after entering 2026, the semiconductor index embarked on a steep, independent rally, with short-term gains nearing 40% to hit a record high, while the software sector had retreated about 30% from its peak, placing the semiconductor index in a clearly overheated, overbought zone.
Some analysts pointed out that even after a 4% plunge, the Philadelphia Semiconductor Index remains near historic highs, stating that "a pullback is healthy, not a change in direction."
This view is supported by internal analysis from a quantitative hedge fund manager.
He noted that from a technical analysis perspective, the semiconductor index's sharp decline appears more like a short-term correction to an overextended prior move, rather than a fundamental shift.
Combined with an assessment of the SOXX-to-IGV ratio trend, he believes a "pendulum swing back" caused by overly crowded positioning is inevitable, but crowding does not signify the end of the overall trend.
In his view, the true lesson from the Broadcom case for the market is that when expectations run too far ahead, the earnings report itself becomes the "perfect excuse" to exit.
Signals from the Options Market: The Smart Money Has Arrived
In stark contrast to the surface-level panic in the broader market, the derivatives market is sending strong signals to buy the dip.
Christopher Jacobson, co-head of derivative strategy at Susquehanna International Group, noted that investors who missed the chip stock rally are viewing this pullback as a long-awaited "discounted buying opportunity."
A significant number of clients are selling put options on暴跌 chip stocks like Broadcom and Micron—this is essentially a bullish bet: selling puts means investors are willing to buy the stock at a specific price, effectively wagering that the share price will not fall further.
Jacobson further stated that experienced investors are employing a more refined strategy—holding individual stocks for long-term investment while using exchange-traded funds (ETFs) to hedge their exposure.
This "long individual stocks + ETF hedge" combination reflects their cautious anticipation that the market may remain volatile in the short term, but it is not a reversal of their overall view on the AI trade.
"Investors have recently realized significant gains in chip stocks," Jacobson said, "so they are turning to ETF products to hedge."
The options market also had early warning voices.
It was reported that approximately $40 million in block orders established short-term bearish positions in the triple-leveraged Semiconductor ETF (SOXL), betting on a short-term pullback in the sector but judging its nature as "short-term" rather than a structural trend reversal.
This logic bears a high resemblance to previous cases in the crypto space, which similarly relied on narrative-driven rallies and experienced sharp volatility: the fuel for market gains is "narrative" rather than "realization," and when the narrative can no longer consistently exceed expectations, the bubble undergoes a round of "deleveraging."
Colton Loder, executive partner at alternative investment firm Cohalo, expressed a similar judgment—he believes the disappointment over Broadcom's guidance reflects more on the company's own competitive cadence rather than a universal challenge facing the entire chip industry.
Once the market digests this differentiation, "the early morning concerns could gradually ease."
He stated in a media interview: "The disappointment over Broadcom's AI chip guidance led to a deterioration in market sentiment this morning, but once traders realize this may be more of a company-specific issue rather than a broader problem plaguing chipmakers, these concerns may ease amid these worries."
