U.S. Healthcare Stocks Plummeted 30% Four Days Ago, Rebounded 5% Today... Is Bargain Buying Starting?

Option Care Health Inc. (OPCH) closed at $21.03 on the Nasdaq on May 4, up 5%. Volume surged to about 5.06 million shares—well above its norm—and its market capitalization reached roughly $3.3 billion (about KRW 4.5 trillion). In a single day, the company’s valuation grew by approximately $170 million (around KRW 200 billion).

Earlier, on April 30, the company’s Q1 2026 results showed revenue up just over 1% year-over-year and margin compression, prompting it to lower guidance. That announcement sent the share price tumbling more than 30% to the $18 range. On top of that, at the end of March Option Care Health amended its first-lien credit agreement to expand its revolving credit line by $450 million, bringing the total facility to $850 million (about KRW 1.1 trillion), a move that bolsters its financial flexibility.

Option Care Health is the largest independent home and alternate-site infusion services provider in the U.S., created by the 2019 merger of Option Care and BioScrip. Headquartered in Bannockburn, Illinois, it’s widely regarded as a long-term growth story amid rising demand for outpatient intravenous therapy.
