Activision Blizzard set to join the S&P 500

Newsbrief: Call of Duty and World of Warcraft publisher Activision Blizzard will join the S&P 500 today, replacing Pall Corp on the stock market index. 

The publishing giant will be officially instated when trading stops at the end of the day.

"We believe we are well-positioned for long-term growth, and we look forward to continuing to deliver value to our audiences and investors," Kotick said in a statement.

The move cements the company's status as one of the industry's biggest players, with the S&P 500 viewed by many as the best representation of the U.S. stock market, and a pacesetter for the U.S. economy.
