SOXX Drops 21%: Is the AI Trade Over?

The iShares Semiconductor ETF (SOXX) tumbled 21.2% in July, a sharp reversal after a stunning 112.8% rally in the first half of 2026. The ETF, which holds major chip stocks benefiting from the AI build-out, was hit by a combination of profit-taking, bearish bets, and forced selling.

One major catalyst was Michael Burry, the investor famous for predicting the 2008 housing crash. On June 30, he revealed on his Substack that he had shorted SOXX and individual stocks like Nvidia (NVDA) and Micron (MU). Burry argued that AI stocks were extremely overvalued, comparing the boom to the dot-com and housing bubbles. He even increased his short positions during the month, calling a late rally a 'dead cat bounce.'

Sentiment worsened on July 16 when Chinese AI lab Moonshot released Kimi K3, an open-source model with 2.7 trillion parameters that matched or beat top U.S. models from OpenAI and Anthropic on some tasks. Investors worried that cheaper, capable open-source models would force U.S. labs to cut prices, potentially threatening their massive cloud computing commitments to hyperscalers—the biggest buyers of chips.

Adding to the chaos, the hedge fund Situational Awareness, run by ex-OpenAI researcher Leopold Aschenbrenner, 'blew up' in July. The fund had used up to 400% leverage on its AI stock positions, and when the market turned, margin calls forced it to sell its public portfolio to Citadel at a discount. This forced selling likely amplified the decline.

It's worth noting that the sector was ripe for a pullback after such a massive run. Historically, even strong trends see corrections, and the AI trade had been nearly vertical. The combination of valuation concerns, high-profile shorting, and forced liquidations created a perfect storm for the ETF.

For investors, the key question is whether July's sell-off is a healthy correction or the beginning of a prolonged downturn. The answer hinges on the durability of AI demand, which has been the primary driver of semiconductor stocks.

Despite the negative headlines, semiconductor companies reported extremely strong results in July, with no signs of weakening AI-related demand. In fact, many companies noted that demand is accelerating. This suggests that the fundamental thesis for AI infrastructure remains intact, even if sentiment has soured.

However, the presence of skeptics like Michael Burry and the collapse of a leveraged hedge fund highlight the risks of a crowded trade. If AI spending slows or if open-source models reduce the need for expensive proprietary models, chip demand could suffer. But so far, there's little evidence of that happening.

Historically, the AI trade has weathered several panics—like the DeepSeek scare in early 2025 and the TurboQuant panic in early 2026—and each time, stocks recovered and marched higher. This pattern suggests that July's drop might be another dip in a longer-term bull market.

For investors, the sell-off could be a chance to buy quality semiconductor stocks at a discount, but it's essential to stay cautious. The high valuations and leverage in the system mean volatility could persist. Keeping a long-term perspective and focusing on companies with strong fundamentals is key.
