Why did UNH stock drop about 20% today?

The market reacted to the CMS rate proposal showing only a 0.09% Medicare Advantage increase. That suggests tighter pricing power and possible margin pressure into 2026, which outweighed an earnings beat and slightly better guidance. Heavy volume signaled de‑risking across managed-care names while investors wait for final rates in early April.

What does the CMS rate proposal mean for margins and MLR?

A near-flat Medicare Advantage rate limits revenue per member growth. If care costs trend higher, the medical loss ratio can rise, compressing margins. Plans may respond with benefit redesign, network tweaks, or pricing changes. Final rates in early April will set the revenue baseline that determines 2026 margin potential.

Is UNH stock attractive after the selloff?

Valuation reset to roughly 14.7x EPS with a 3% dividend yield and strong free cash flow. Analysts skew positive, with 32 Buy, 5 Hold, and 2 Sell ratings. Our system shows a B+ grade with a BUY suggestion, while a separate company rating is Neutral. The April rate decision remains the key risk.

What dates should Hong Kong investors watch for UNH stock?

Focus on the CMS final Medicare Advantage rates in early April, plus any management updates on benefit design and MLR. Also monitor sector peer commentary for read-through. US headlines can move prices during Asia hours, so set alerts and review broker notifications for premarket changes.

How should HK investors handle USD exposure when trading UNH stock?

Most HK brokers settle US trades in USD and display an HKD equivalent. Consider your USD allocation, potential hedging through your broker, and fees for FX conversion. Keep position sizes modest until the rate outcome is known. Review account settings to manage currency risk and cash balances efficiently.
