Health-care stock performance diverged Friday after the controversial GOP health care bill was pulled from the floor of the House of Representatives .
UnitedHealth (NYSE: UNH), Anthem (NYSE: ANTM) and Cigna closed lower. The three stocks would have been among the top winners if the bill had passed, Leerink Partners analyst Ana Gupte said on CNBC's " Squawk Box ."
Cigna (NYSE: CI) fell 2.25 percent in its worst day of the year so far. The stock was also the worst performer in the S&P 500's health care sector. The second worst performer was Anthem, which fell more than 1.5 percent in its worst day since Feb. 17.
Health care sector five-day performance
On the other hand, hospital stocks leaped. The industry is among those opposed to the health-care proposal as it was expected to result in an increase in Americans without health insurance, which could drive up hospital losses. Tenet Healthcare (NYSE: THC) shares climbed 7.4 percent in its best day since March 3. Community Health Systems (NYSE: CYH) gained more than 9.5 percent and Acadia Healthcare (NASDAQ: ACHC) rose nearly 6 percent.
In managed care, Molina (NYSE: MOH) rose 4.6 percent in its best day since Nov. 14, while Centene (NYSE: CNC) gained 5.2 percent in its best day in more than a month.
The overall health-care stock sector closed 0.02 percent lower, down 1.3 percent for the week, its worst performance since Jan. 20, amid tense Congressional debate over the GOP health-care proposal.
The decision to pull the bill occurred late in Friday's trading session, sending the stock sector for a choppy last half hour of trade. The iShares Nasdaq Biotechnology ETF (IBB) (NASDAQ: IBB) closed off session highs, up 0.37 percent.
"I think we have to let Obamacare go its way a little while," President Donald Trump said in a press conference late Friday afternoon. He added tax reform would be the next priority for Congress.
