Jim Cramer Says Yahoo! (YHOO) CEO Marissa Mayer Continues to Shine

NEW YORK (TheStreet) -- Yahoo!  (YHOO) announced Tuesday it would buy video-advertising platform BrightRoll for approximately $640 million. TheStreet's Jim Cramer says CEO Marissa Mayer made this acquisition in video, the one area in which margins have held up on the web.

Cramer points to some investors who are still unhappy, who believe Yahoo! should merge with AOL  (AOL) and who say Tim Armstrong should run the combined company. But Cramer says AOL stock has not done anything this year, while Mayer continues to deliver at Yahoo!

Cramer then says some investors think Yahoo!'s successes are all due to Alibaba  (BABA) , but he thinks it doesn't matter what the source is because a company can truly grow when it becomes flush with money and can buy back stock (which Yahoo! has done) and make strategic acquisitions.
