Leveraged Semiconductor Fund Drops as AI Skepticism Triggers Sell-Off
- The Bet: Market participants drove a record $6.1 billion into the 3x leveraged semiconductor fund last week to capitalize on falling chip valuations, according to marketwatch.com.
- The Fallout: The fund fell another 10.8% and booked its third straight weekly decline, with an October drop projected past 43%, marketwatch.com reported.
- The Catalyst: Renewed skepticism regarding investment returns on the artificial intelligence infrastructure buildout triggered a broader sell-off across tech equities, according to marketwatch.com.
Valuation Realities Hit the Artificial Intelligence Trade
Chip stocks have soared this year as processing hardware remains vital for artificial intelligence development, marketwatch.com reported. But October introduced mounting pressure as traders questioned whether the aggressive pace of corporate spending on AI infrastructure is sustainable. That uncertainty fueled severe daily swings across technology equities.
“The semis have been so sensitive to the AI-infrastructure buildout,” Mike Reynolds, vice president of investment strategy at wealth-management firm Glenmede, said in a phone interview, according to marketwatch.com. “The AI trade has come under some skepticism here.”

Those fluctuations created a speculative frenzy around leveraged exchange-traded funds designed to amplify daily returns via derivatives. The Direxion Daily Semiconductor Bull 3X ETF aims to provide 300% of the daily swings of a popular underlying index. Daily inflows persisted until Thursday, when semiconductor shares dropped precipitously, marketwatch.com reported.

Reassessing the Chip Rally After Massive 2026 Gains
Despite recent losses, the iShares Semiconductor ETF remains up almost 59% for the year, according to marketwatch.com. The October reversal has prompted market participants to reevaluate valuations following an extended, aggressive rally.
“At these valuations and after a rally that’s been this aggressive, it’s healthy that investors are taking a sober second look” at potential returns from the artificial intelligence theme, Reynolds said, according to marketwatch.com. He added that it is beneficial for “investors are questioning this in real time before you reach those peak euphoria moments where things get completely detached from reality in fundamentals.”
