Humana (HUM) stock is plunging in Wednesday's session after the health benefits company announced preliminary 2025 Medicare Advantage (MA) Star Ratings data provided by the Centers for Medicare and Medicaid Services (CMS).
HUM is down 15% at last check, making it the worst S&P 500 stock so far today. And this follows a 12% decline in the stock yesterday when the CMS plan finder website included Star Ratings for 2025 plans.
