LinkedIn reported that second-quarter revenue rose almost 90 percent and raised its full-year outlook on Thursday. Its shares were up 12.1 percent at $104.80 on Friday morning on the New York Stock Exchange.

"The company just appears to get better in what would otherwise seem to be a very tough environment," Evercore analyst Ken Sena wrote in a note.

In a note to investors, UBS analyst John Janedis wrote that for CBS "the earnings momentum story of the past two years continues to play out."
