Facebook has just ascended to one of the most closely watched measures of the global market for stocks, the Standard & Poor’s 500 index.
According to a statement from S&P Dow Jones Indices, a division of McGraw Hill Financial, Facebook will also join the S&P 100.
In both cases it will replace other companies which are being shifted to other indices. On the S&P 500, it will replace Teradyne, the maker of test and measurement equipment, which will shift to the S&P MidCap 400 index. On the S&P 100, Facebook will replace The Williams Companies, a player in the energy business.
Facebook shares rose by more than four percent in after-hours trading after the news was announced. As of the close of regular trading today, the shares had risen by more than 85 percent this year.
