Expectations Outrun eBay's Growth

This article brings up great questions about what drives a company's stock price. The article states that eBay is still expected to grow EPS next year by 34%. But yet, the stock price fell on that news.

eBay's growth would please just about everybody -- except the company's own investors. The online-auction company's stock has been priced at sky-high levels. That's been OK as long the company has been able to deliver stratospheric growth.

But with eBay's growth rates starting to fall, as the company warned Thursday, investors may wonder what exactly they're paying for. Actually, they did more than wonder, promptly taking eBay shares down $3.59, or 6.2%, to $53.91 in after-hours trading.
