Why did UNH stock drop so much today?

UNH stock today reflects a sharp reset after CMS signaled only a 0.09% increase to Medicare Advantage rates. That implies limited revenue support while medical costs remain firm, which squeezes margins. The policy surprise overshadowed mixed UnitedHealth earnings and a cautious outlook, triggering heavy selling and high trading volume.

What numbers should German investors track now?

Watch the share price versus the 50-day and 200-day averages, medical loss ratio commentary, and updates on Medicare Advantage rates. UNH stock today trades near 283 USD with elevated volume, a PE around 14.7, and a dividend yield near 3%. The final CMS rate decision is the key catalyst.

Does the selloff change the long-term thesis?

It shifts near-term margin and growth assumptions, but the long-term depends on the final Medicare Advantage rates, utilization trends, and execution across Optum units. UNH stock today prices in higher risk. If the final rate improves and costs stabilize, part of the drawdown could retrace. Policy remains the swing factor.

How can I manage risk when buying this dip?

Use staged entries and clear stop levels. Avoid market orders during wide spreads. Size positions for a weak final rate scenario. UNH stock today trades below key averages, so wait for signs of stabilization like strong closes on rising volume. Consider hedges if exposure is large relative to your portfolio.
