A financial firm commented on today's market trends. Despite Broadcom posting strong earnings, its shares dropped 6% in after-hours trading—what exactly happened? The unexpected move seems incomprehensible. There appears to be little evidence that massive investments in AI are translating into tangible improvements in productivity or profitability. Additionally, concerns over the inflated valuations of tech stocks and a series of cyclical trading patterns have raised warnings about a potential AI bubble.
Futures linked to major U.S. stock indices suggest mixed performance ahead of the final trading session of the week. Broadcom’s shares fell during after-hours trading, with the latest updates from the chipmaker triggering renewed concerns about surging investments in artificial intelligence. Costco reported better-than-expected earnings, underscoring strong demand for low-cost goods among budget-conscious Americans ahead of the holiday season. Lululemon Athletica announced the resignation of its CEO amid reports that the founder is considering launching a proxy fight. Crude oil prices rose due to supply concerns stemming from the possibility of the U.S. further blocking Venezuelan oil tankers.

1. Futures show mixed signals.

U.S. stock futures traded on both sides of the flatline on Friday, signaling a subdued end to a week highlighted by key central bank interest rate decisions and important earnings from the artificial intelligence sector.
At 02:00 ET (07:00 GMT), Dow futures contracts were up 105 points (0.2%), S&P 500 futures were nearly unchanged, while Nasdaq 100 futures declined by 36 points (0.1%).
The benchmark S&P 500 and blue-chip Dow Jones Industrial Average closed at new all-time highs on Thursday, supported by the Federal Reserve's policy update, which many interpreted as more balanced and less hawkish than initially expected. Analysts at Vital Knowledge suggested that Fed Chair Jerome Powell had given the 'green light' to a year-end stock market rally through this decision.
However, Oracle's bleak financial forecast has the potential to damage market sentiment and exacerbate growing concerns about the sustainability and ultimate profitability of the AI boom. In addition to Oracle’s stock price dropping more than 10%, its bonds were sold off, and credit default swaps, which provide a hedge against potential default, were purchased, reflecting concerns over the company’s debt-driven ambitions in AI.
Oracle’s gloomy outlook pushed down the Nasdaq Composite Index, which is heavily weighted with technology stocks, by 60.30 points (0.25%).

2. Broadcom Points to Impact of AI Revenue on Margins

Meanwhile, shares of Broadcom fell in after-hours trading as the semiconductor giant, a rival to Nvidia, warned that its margins would be reduced due to the dilutive effect of AI-related revenue.
Eager to disrupt Nvidia's long-standing dominance and gain market share in the race to build processors that support the AI surge, Broadcom has heavily invested in this emerging technology. CEO Hock Tan stated during an earnings call with analysts that Broadcom’s backlog now stands at $73 billion, with plans to ship these products over the next 18 months.
However, a phrase increasingly heard in the tech industry is that the push into AI comes at a substantial cost. These massive investments could pressure Broadcom’s profit margins, a fact acknowledged by CFO Kirsten Spears, who noted that the company’s consolidated gross margin for the first quarter would decline by approximately 100 basis points from the previous quarter.
Major U.S. cloud providers are expected to spend over $400 billion on AI this year, with significant investments directed toward building cutting-edge data centers required to support AI models such as OpenAI’s ChatGPT and Google’s Gemini.
However, the lack of evidence showing that this surge in spending leads to tangible improvements in productivity or profits, coupled with high valuations of technology stocks and a series of cyclical trades, has raised warnings about the possibility of an AI bubble.
Broadcom’s fourth-quarter earnings exceeded expectations, marking one of the last major events on the 2025 AI calendar. Traders are now focusing on upcoming earnings reports later this month from Apple supplier Jabil and semiconductor group Micron Technology.

3. Costco Wholesale Earnings Exceed Expectations

Elsewhere, Costco's shares edged slightly lower in after-hours trading despite the warehouse retailer, known for its budget-conscious offerings, reporting better-than-expected earnings and profits for the first quarter.
Excluding gasoline, same-store sales for the quarter ended November 23 rose by 6.4%, surpassing analysts' expectations of a 5.82% increase, according to data from LSEG cited by Reuters.
Costco’s strengths are further bolstered by its same-day delivery partnerships with Instacart in the U.S. and UberEats and DoorDash in international markets.
Costco, the retail giant known for its large membership-based stores and bulk purchase discounts, reported results consistent with similarly robust figures from competitors such as Walmart, Dollar Tree, and Dollar General. This trend highlights how many U.S. consumers are seeking value amid widespread economic uncertainty, characterized by a weakening job market and persistently high inflation.

4. Lululemon CEO to Step Down

Shares of Lululemon Athletica surged more than 10% in after-hours trading following the athleisure group's announcement of CEO Calvin McDonald's resignation and an upward revision of its full-year profit forecast.
McDonald, who has served as the head of the company renowned for its premium athleisure wear and leggings for seven years, is set to step down in January without immediately naming a successor. He will remain as a senior advisor until March but will relinquish his board seat.
According to The Wall Street Journal, McDonald’s departure comes as the company’s founder, Chip Wilson, is informally preparing to launch a proxy fight, meeting with potential investors and consulting with advisors.
The WSJ reports that Wilson’s actions are partly driven by dissatisfaction with Lululemon’s marketing strategy, though it remains unclear whether McDonald’s departure will influence Wilson’s potential proxy battle.

5. Crude Oil Rises Amid Supply Concerns Over Venezuela

Crude oil prices rose on Friday as expectations that the United States would further block Venezuelan oil tankers deepened supply concerns.

Brent futures rose 0.5% to $61.56 per barrel, while U.S. West Texas Intermediate crude futures climbed 0.5% to $57.90 per barrel.
However, both benchmarks were on track for weekly losses after dropping approximately 1.5% on Thursday amid prospects of a potential peace agreement between Russia and Ukraine.
This is because the likelihood of Russian oil being supplied to the global market increases if there is a possibility of a peace agreement between Russia and Ukraine.
