The Nasdaq Composite found buyers after its worst session in 18 months, rebounding roughly 1% as traders stepped back into technology shares. But the bounce arrives with a question attached: is this the beginning of durable dip-buying, or merely the market catching its breath after a brutal rush for the exits?

That distinction matters because Thursday’s sell-off was not a gentle clearing of the decks. The S&P 500 fell 4.4%, its worst daily loss amid the AI-driven technology sell-off, leaving momentum traders with a fresh test: can technology shares hold their recovery, or will the rebound prove as temporary as a spark in a windstorm?

The Nasdaq’s return to positive territory suggests that some traders were willing to look past the damage and buy back into the sector. That is a meaningful shift in tone, particularly after the index’s worst session in 18 months. Yet a one-session rebound does not, by itself, establish that the AI correction has ended. It shows appetite returning; it does not settle whether conviction has returned with it.

For traders, the market’s next task is less about celebrating the 1% move than interpreting its quality. A rebound following a steep decline can carry two messages at once. It may indicate that buyers see the sell-off as an opportunity to re-enter technology shares. It may also reflect short-term positioning after an unusually sharp decline. The market has supplied the first part of the argument—the bounce—but not yet the full answer.

Lam Research provides a powerful single-stock catalyst

Lam Research added a separate jolt of energy to the technology trade. The semiconductor-equipment company rose more than 11% in premarket trading after its board authorized a $25 billion stock buyback. Identified by its ticker, $LRCX, the company became a focal point for traders looking for a concrete catalyst inside a market still wrestling with broader AI-related pressure.

A buyback authorization can support sentiment around an individual stock by signaling that the board is prepared to commit substantial capital to repurchases. That signal may give traders a clearer reason to reassess $LRCX after the sell-off, especially when the broader technology group is attempting to regain its footing. Still, the authorization speaks directly to Lam Research—not to the Nasdaq as a whole—and should not be treated as evidence that the wider market has turned.

“The rebound has a real test ahead: can buyers do more than react to Thursday’s damage?”

The contrast between the index and $LRCX is instructive. The Nasdaq’s roughly 1% rebound reflects a broader return to technology shares, while Lam Research’s more than 11% premarket move was tied to a specific corporate announcement. One is a market-wide sentiment check; the other is a company-level catalyst. Blurring those signals could make the recovery look sturdier than the evidence currently supports.

A bounce, not a verdict

The most useful reading of the session may be that traders are testing the waters. After the S&P 500’s 4.4% decline and the Nasdaq’s worst session in 18 months, the willingness to buy technology shares again is significant. But the market still needs to demonstrate that demand can persist beyond the initial rebound.

That leaves the AI-driven sell-off unresolved. The Nasdaq’s roughly 1% recovery could become the first step toward steadier momentum, or it could remain a short-term bounce shaped by the shock of Thursday’s decline. For now, the tape offers a signal of renewed interest—not a declaration that the storm has passed. Lam Research’s buyback gives $LRCX a company-specific lift, while the broader Nasdaq must still prove that dip-buyers can keep the engine running.
