WHAT PEOPLE ARE SAYING

Healthcare sector strength, particularly driven by positive clinical trial outcomes in cancer treatments and strong biotech ETF performance with gains exceeding 90% over the past year, is contributing to broader market recovery. This sector-specific strength provides a counterweight to weakness elsewhere.
