UNH Stock Surges 38.8% in Six Months Amid Improved Medical-Cost Trends

UnitedHealth Group Incorporated (UNH) has seen its stock price rise by 38.8% over the past six months, outperforming both the industry average and the S&P 500.

This rebound is attributed to improving medical-cost trends, which indicate that UnitedHealth's pricing, benefit design, and cost controls are working effectively.

The company's medical care ratio has decreased from 87.1% in 2025 to 85.3% in the first half of 2026, while medical costs have declined by 2% to $148.8 billion.

UnitedHealth is also reducing its exposure to weaker-return businesses and redirecting capital towards areas with better return potential, which could lead to improved profitability and execution.
