Nvidia Earnings Fail to Quell AI Doubts

When Nvidia (ticker: NVDA) reported earnings after Wednesday’s close, it appeared that concerns about an AI bubble had been well and truly squashed. Nvidia beat both earnings and revenue expectations, and CEO Jensen Huang extolled that sales were “off the charts.” Indeed, the company grew earnings 62 per cent year over year. When the market opened on Thursday, NVDA and the S&P 500 were up five per cent and 1.5 per cent, respectively. Sentiment quickly shifted mid-morning, however, when investors dove deeper into the company’s financial statements. One notable concern was customer concentration: over the nine months ending October 2025, more than one-third of Nvidia’s data center revenue came from only two customers. Last year, a similar percentage came from three customers.

NVDA finished Thursday down more than three per cent and ended the week down six per cent. The sell-off affected many other tech stocks. AI darling Palantir (ticker: PLTR), which trades at an astonishing 161x forward earnings, was down 11 per cent for the week. NVDA and PLTR are still well into positive territory this year, up 33 per cent and 105 per cent, respectively. The S&P 500 closed the week down two per cent but has still returned more than 12 per cent this year.

Last week’s volatility emphasized the importance of holding a diversified portfolio. The 10-year US Treasury yield decreased to 4.06 per cent from 4.14 per cent, as investors rotated into safe haven assets. As a result, both investment-grade and high-yield bonds saw gains. Real Estate Investment Trusts (REITs), which are rate-sensitive, also generated positive returns.

Despite the tech sell-off, investors could find returns elsewhere in US equities. The iShares US Healthcare ETF (ticker: IYH) and the iShares US Consumer Staples ETF (ticker: IYK) returned 1.9 per cent and 1.1 per cent, respectively. Stocks within these sectors tend to be relatively isolated from economic downturns. IYH’s largest constituent, Eli Lilly (ticker: LLY), made headlines this week when it became the first healthcare company to achieve a $1 trillion valuation. Lilly’s weight-loss injection Zepbound and diabetes treatment Mounjaro have led to the company’s dominant 58 per cent share of the GLP-1 antagonist space. The company’s dominance could position it well when GLP-1s for weight loss transition to oral delivery, which is expected in 2026.
