Key Points

Stocks tumbled Friday, with tech stocks leading the declines, after a flush of so-so earnings from major players in artificial intelligence reignited caution about the sector.

These stocks made moves Friday:

Broadcom sank 11%. The chip maker reported better-than-expected results for its fourth fiscal quarter, but failed to ease investors’ concerns over its customers. Wall Street has been worried about big chip makers’ reliance on ChatGPT developer OpenAI, the loss-making startup. On an earnings call, analysts questioned the chip maker’s sales forecasts and future margins.

Oracle fell 4.5%, deepening its losses after plunging 11% in the previous session. Bloomberg reported on Thursday that Oracle has delayed completion dates for some of the data centers it’s developing for OpenAI. In a statement to Barron’s, Oracle said “there have been no delays to any sites required to meet our contractual commitments, and all milestones remain on track.” On Wednesday, the company raised its spending forecast and issued guidance that fell short of estimates. Oracle also failed to mitigate investor concerns over the size of its outstanding debt.

Fermi cratered 34%, its worst day on record. The energy and data-center infrastructure company said it had lost a $150 million construction funding commitment from the first major tenant at its Project Matador campus in Texas.

Lululemon Athletica jumped 10% after the retailer topped analysts’ expectations for third-quarter earnings and revenue. Lululemon also announced that CEO Calvin McDonald plans to step down on Jan. 31. Lululemon’s board has yet to name a permanent successor.

Costco Wholesale stock was flat after the warehouse retailer reported solid fiscal first-quarter earnings. Investors were likely hoping for even stronger numbers. Costco has lost momentum this year, falling 4%—a surprising reversal for a stock that has long outperformed the market.

RH jumped 5.7% after the furniture company missed analysts’ third-quarter earnings targets but beat on revenue. RH’s sales guidance came in weak: It expects 7% to 8% growth over the current quarter, softer than the 10% jump that Wall Street had forecast.

Bristol Myers Squibb rose 2.4% to $52.41. Shares were upgraded to Buy from Neutral at Guggenheim with a $62 price target. The stock has fallen 7.3% this year, but analysts with the firm say its underperformance “presents a buying opportunity before a catalyst-rich 2026” that could drive shares above $60.

Tilray Brands and Canopy Growth soared 44% and 53%, respectively, following reports that President Donald Trump could loosen federal restrictions on marijuana early in 2026. Trump indicated in August that he was weighing the pros and cons of reclassifying cannabis. A White House official told Barron’s no final decisions on marijuana reclassification have been made.

Netskope declined 12%. The cybersecurity company posted a narrowr-than-expected third-quarter loss and revenue that topped Wall Street estimates. while guidance came in slightly above expectations. Netskope expects revenue in the fourth quarter of $188 million to $190 million, better than expectations of $185.5 million.

Shares of Quanex Building Projects, a small-cap manufacturing company, gained 10%. The company swung to a profit in its fiscal fourth quarter, which overshadowed a mixed print and Quanex not issuing “official guidance” for fiscal 2026.
