Top Stock Movers – April 23 2026

U.S. equities lost momentum Thursday, with the S&P 500 and Nasdaq Composite reversing from fresh record highs to close in the red. A sharp selloff in software stocks and renewed geopolitical tensions overshadowed strength in select energy-linked and industrial names.

Losers: Software Rout Leads Declines

Technology stocks bore the brunt of the downturn, with earnings disappointments and macro concerns triggering broad selling:

ServiceNow plunged ~18%, the session’s worst performer, after warning that Middle East tensions are weighing on subscription growth.

IBM dropped ~8%, despite posting an earnings beat, as investors showed little tolerance for unchanged guidance.

Microsoft fell ~4% amid reports of workforce buyouts tied to rising AI costs.

Tesla slid ~3.5%, extending post-earnings weakness as heavy AI spending plans raised concerns about near-term cash flow.

Lululemon Athletica declined ~6% after naming a new CEO, a move that failed to reassure investors.

Winners: Energy, Airlines, and Niche Plays Stand Out

Despite the broader selloff, several stocks posted gains:

American Airlines rose ~4%, even after cutting its full-year profit outlook, as investors looked past rising fuel costs.

Oklo gained ~5% following a partnership announcement with Nvidia focused on AI-driven nuclear research.

Intel edged ~2% higher ahead of its earnings release, bucking the broader tech downturn.
