Wall Street Applauds… Healthcare Tech Stocks Surge by 1.6 Trillion Won in a Day

Oscar Health Inc. (NASDAQ: OSCR) closed at $23.61 on the New York Stock Exchange, up 15.17% on volume of 5.55 million shares. Its market capitalization swelled to about $6.28 billion (roughly KRW 8.8 trillion), marking a one‐day increase of approximately $1.12 billion (around KRW 1.6 trillion).

The sharp rise followed Wells Fargo’s upgrade of Oscar Health’s investment rating from Underweight to Equal Weight and its near‐doubling of the price target from $11 to $20, citing an improved trend in the company’s 2026 ACA exchange business. Intra‐day trading saw the stock top $20, and it has gained more than 40% over the past year.

Oscar Health is an insurtech firm that sells individual and small-business health insurance online in the U.S. In the first quarter of 2026, it reported adjusted EPS of $2.07, well above the consensus of $1.06, and reaffirmed its guidance. Earlier, CEO Mark Bertolini reinforced investor confidence by purchasing 1 million shares of the company’s stock in April for about $11.92 million, a “bet on his own company” valued at roughly KRW 17 billion.
