NEW YORK ( TheStreet) -- Marissa Mayer has been good for her company. Since taking over as CEO of Yahoo! ( YHOO), the stock has surged more than 40%.
In the midst of a stock market correction today, Oppenheimer raised its rating on Yahoo! to "buy" and lifted the price target to $27 from $22. Behind the increased bullishness was the fact that Alibaba (of which Yahoo! owns 24%) may go public with an IPO valued at a staggering $77 billion and Yahoo's increasing revenue from its search engine. Another big reason Yahoo! is doing so well since Mayer's appointment is her financial decisions. After repurchasing $1.5 billion in shares in the fourth quarter, Yahoo! is still buying back shares at a quick pace. According to the company's annual security filing, Yahoo! purchased $663 million of its stock in the first two months of 2013. That means since the beginning of November, it has repurchased almost $2.2 billion of its shares at an average price that's less than $19 a share. That's smart financial maneuvering! In a March 19 SEC filing, Mayer disclosed that after recently selling 19,264 shares of Yahoo!, she still owns 2,637,802 shares, which after today's 3.5% jump, she owns over $60 million in stock.
