玛丽莎•梅耶尔——雅虎

2012年7月份加入雅虎（Yahoo）后不久，梅耶尔就开始回购股票，同时收购了一些知名的公司和产品，比如轻微博平台Tumblr和移动新闻软件Summly。虽然她因此得到了华尔街的青睐，但这阵喧嚣并没有改善雅虎的收入情况。2012年，也就是梅耶尔成为首席执行官的第一个年头，雅虎的收入只增长了2%。近期雅虎股价上涨的大部分动力都来自它对阿里巴巴（Alibaba）和雅虎日本（Yahoo Japan）的投资，而不是这家公司的主营业务取得了成功。

Marissa Mayer -- Yahoo

Though Mayer won Wall Street's favor with stock buybacks and big-name acquisitions -- like Tumblr and Summly -- soon after joining Yahoo in July 2012, the buzz over Yahoo hasn't been reflected in its revenue, which increased by only 2% in her first calendar year as CEO. The gains Yahoo's (YHOO, Fortune 500) stock has made of late are mostly a result of its investments in Alibaba and Yahoo Japan, not the success of its core business.
