One year later, Yahoo CEO proves a shareholder favorite

It's been exactly one year since Marissa Mayer became Yahoo's CEO, and her company's shares are up 74 percent.

In many cases, CEOs are judged by their company's share price. If that's the case with Yahoo, Melissa Mayer has won over her bosses.

Mayer was appointed CEO on July 16 of last year when Yahoo's share price hovered around $15. As of this writing, the company's stock has risen 74.4 percent to land at $27.24.

Mayer, who formerly worked at Google, has made a host of changes at Yahoo in the past year, including acquiring several major online services firms, such as Tumblr, and bringing much-needed stability to the chief executive office.

Still, Mayer has done little to change the trajectory Yahoo was on prior to her arrival. The company is no closer to being a major competitor to Google than it was when she started. Despite generating profits every quarter since she joined Yahoo, revenue has remained about static.

So, what are shareholders betting on? It's tough to say, and handicapping the stock market is notoriously difficult. But for now, it appears that Mayer has the confidence of her company's board and shareholders, and that could be the first step in a steady, upward climb.
