Most overbought stocks after a volatile week
CNBC Pro identified several stocks that moved into overbought territory after a volatile week for markets. Hewlett Packard Enterprise (HPE) was among the most overbought after reporting a fiscal Q2 earnings beat — adjusted EPS of $0.79 on $10.68 billion revenue vs. LSEG estimates of $0.53 and $9.79 billion — and climbed about 14% on the week. Loop Capital upgraded HPE and raised its price target. Cybersecurity firm Fortinet also appeared overbought after swings tied to peers' results, finishing the week with a high RSI. Host Hotels & Resorts and Humana were additionally flagged as overbought based on 14-day RSI readings above 70. The piece uses CNBC Pro’s stock screener and 14-day RSI to define overbought/oversold status.
Stock Market Holds Highs Despite Rising Yields and Oil
The stock market remains near all-time highs despite rising Treasury yields and oil prices. Analysts attribute this resilience to the heavy concentration of tech stocks in the S&P 500 and Nasdaq, which have been buoyed by strong earnings expectations and the AI buildout. The Dow Jones, more sensitive to cyclical concerns, is down 6% from its August record. Investors are betting on a strong earnings season, with S&P 500 companies expected to post over 29% blended earnings growth. Yields are at multi-decade highs, but many see this as normalization rather than inflation. Oil prices, while elevated, have not yet dented profit outlooks, with Russell Investments suggesting prices would need to stay above $100-120 for months to hurt equities. Consumer spending remains resilient, supporting the market.
Four forces drove a tough week for stocks
Stocks fell for a second consecutive week as investors reacted to rising geopolitical tensions in the Middle East, a sharp spike in oil prices, mixed tech earnings and healthcare catalysts. The S&P 500 slipped 0.6% and the Nasdaq fell 2.1%. Oil jumped—U.S. WTI rose more than 8% and Brent surged nearly 10%, briefly topping $100 a barrel—rekindling inflation concerns and pushing the 10-year Treasury yield to its highest level since January 2025. Earnings headlines included Alphabet raising its capital expenditures outlook despite strong Google Cloud growth, Intel reporting a large data-center revenue increase and GE Vernova showing strong order growth. Healthcare moves included Eli Lilly’s positive late-stage data for retatrutide and Johnson & Johnson’s FDA approval of its Ottava robotic surgery system.
