One trading session does not erase a market dislocation—but a 3.4% Nasdaq-100 rebound demands attention. The index delivered its best single-day performance since May 12, 2025, when it gained 4%, as momentum stocks recovered from the forced selling associated with the so-called “Leopold liquidation.”

The message for traders is clear but incomplete: the selling pressure may have created the conditions for a powerful reversal, yet the market still needs to prove that this was more than a one-day reset. Nasdaq futures were higher ahead of the open, with Amazon’s excellent quarter cited as one contributing factor, while Microsoft’s strong fourth-quarter earnings report added another major catalyst for technology shares.

A violent reversal in market leadership

The Nasdaq-100’s advance substantially outpaced the broader benchmarks. The S&P 500 rose 1.7%, while the Dow Jones Industrial Average gained 1.2%. That performance gap is important. It indicates that the session was not simply a broad, uniform recovery; technology and momentum exposure led the move.

The “Leopold liquidation” is best understood here as a forced-selling event that pressured momentum stocks and disrupted positioning. When that pressure eases, the reversal can be abrupt. Short-squeeze dynamics may amplify the move as traders who positioned for continued weakness reassess their exposure, while momentum participants respond to the sudden change in price action.

That does not make the rebound self-sustaining. A forced-selling event can produce an equally forceful bounce without establishing a durable new trend. Traders need to distinguish between a mechanical recovery from dislocation and a broad improvement in market conditions.

Why Amazon and Microsoft mattered

Amazon’s excellent quarter was cited as a factor supporting Nasdaq futures ahead of the open. Microsoft, meanwhile, emerged as another major catalyst after its strong Q4 earnings report. Gains in Microsoft helped lift the broader technology sector and reinforced the market’s preference for large, influential technology names during the rebound.

For momentum traders, this is the kind of session that can change leadership quickly. Stocks and sectors that were under pressure may regain attention, but chasing a sharp move carries a different set of conditions than trading an orderly trend. Follow-through matters more than the headline percentage gain.

What the rebound means for different market participants

Swing traders may focus on whether the Nasdaq-100 can hold its rebound rather than simply whether it posted a large gain. Momentum traders will be watching for continued leadership from technology and other previously pressured groups. Options participants must also account for the possibility that a one-day reversal changes volatility and pricing conditions without resolving the underlying uncertainty.

Index investors receive a cleaner expression of the move through products such as $QQQ, while $SPY and $DIA provide broader and more diversified benchmark exposure. The difference in their performance is important: the Nasdaq-100 gained 3.4%, compared with 1.7% for the S&P 500 and 1.2% for the Dow. Still, index-level performance does not remove individual-stock risk. Even large constituents such as $MSFT and $AMZN can respond differently to earnings, expectations and valuation pressures.

There is at least one constructive breadth signal. Schwab noted that 73% of S&P 500 components were trading above their 200-day moving average earlier in the week. That suggests the market’s foundation was not entirely dependent on a handful of names, although it does not confirm that the rebound will continue.

For the full market context, CNBC’s report on the momentum-stock rebound captures the scale of the reversal. The next test is follow-through: sustained breadth, stable or declining volatility, and continued leadership beyond a single session. Until those signals appear, the prudent conclusion is that the Nasdaq-100 staged a powerful recovery from forced selling—not that a durable trend has been proven.
