Shares of Incyte (NASDAQ: INCY) closed more than 7 percent higher Friday, on news that the pharmaceutical company will join the S&P 500 (INDEX: .SPX).
Drug development company Incyte will replace Spectra Energy (NYSE: SE) on the S&P 500, effective at the open of trading next Tuesday, S&P Dow Jones Indices said in a press release on Friday.
Such index changes require fund managers whose investments track the S&P 500 to reallocate their holdings, including buying shares of stocks being added to the benchmark index.
Spectra is leaving the S&P 500 given its pending acquisition by Canada-based Enbridge (Toronto Stock Exchange: ENB-CA), an oil and gas pipeline operator, the release said. U.S.-listed shares of Enbridge were 1 percent lower Friday, while Spectra traded little more than 0.5 percent lower.
Incyte specializes in oncology products and will be added to the S&P 500's biotechnology sub-industry index, according to the release.
Incyte shares hit a 52-week high Friday and are up about 30 percent for the year so far.
