Nasdaq 100 Faces a $2 Trillion Wipeout as AI Stocks Slide, and Why Leveraged Funds Need a Closer Look
Reuters reported that more than $2 trillion in market value was set to be wiped from the tech-heavy Nasdaq 100 in October 2026, as investors pulled back from AI-linked stocks. Reuters
The selling was triggered by earnings. Disappointing tech results produced the worst stock drop since June 2026, with the Nasdaq 100 sinking 3.5%, according to Bloomberg. Reuters separately put the late-October slide at 2.9% as worries about AI spending deepened. Reuters The index had fallen 7.8% from its all-time closing high, set on October 6, 2026. Bloomberg described the decline as the third correction of 2026, as bets on tech stocks unwound. Bloomberg
Those figures matter most for anyone holding leveraged exposure to the index. A leveraged fund uses derivatives or borrowing to amplify an index's daily move. ProShares Ultra QQQ (ticker QLD) targets 2x the daily return of the Nasdaq-100, and ProShares UltraPro QQQ (ticker TQQQ) targets 3x. ProShares TQQQ is the fund ProShares describes as the first and only ETF designed to deliver 3x the daily performance of the Nasdaq-100, and it calls it the world's largest leveraged ETF. ProShares ProShares marked the fund's 15-year anniversary in February 2025. ProShares
Flows did not retreat in the same way. Nasdaq.com reported that QLD recorded approximately $292.7 million in inflows, a 2.0% increase week over week. Nasdaq The data point shows that money moved into the fund.
The mechanics deserve more attention than the headlines give them. These funds seek daily investment results, before fees and expenses, corresponding to a multiple of the underlying's daily performance. ProShares calls this the Daily Target. For any holding period longer than one day, a geared fund's return may be higher or lower than its Daily Target. ProShares The reset happens every session, so the multi-day result depends on the path the index takes, not only on where it ends.
Consider the arithmetic. If TQQQ hit its 3x target exactly on a day when the index fell 3.5%, the fund would fall about 10.5% before fees on that session alone. Over a longer window, the compounding cuts both ways. In a steady uptrend, daily rebalancing can produce returns well above the multiple of the index's cumulative gain. Yahoo Finance reported that TQQQ's 3x daily leverage compounded over ten years into a 3,197% return, against a 539% gain in the index. Yahoo Finance The same arithmetic in a choppy, falling market works in reverse. A run of sharp down days followed by partial recoveries can leave a 3x fund well behind the index it tracks.
The broader context here is that the $2 trillion figure measures index value, not a realized loss for any holder. It is a mark-to-market number that will move with every session. For leveraged products, the more relevant question is how the daily reset interacts with volatility over the holding period an investor has in mind. That interaction is hard to forecast, and the recent pullback offers no reliable guide to where the index goes next. Be skeptical of any confident call in either direction, including the ones that circulate after a sharp drop.
