Analyst actions

Lehman Brothers

analyst Holly Becker said

Yahoo!'s

(YHOO)

valuation remains rich -- and though it's off its high -- but that it hasn't discounted the difficult environment the company is facing. Becker maintained her cautious stance and neutral rating.

In a research note, Becker wrote that her "contacts suggest that the environment continues to worsen, and we believe it is only a matter of time before we see the impact on Yahoo!'s results." One issue, Becker notes, is that traditional advertisers aren't embracing online advertising. And if the company's third-quarter revenue is short of estimates -- her estimate is $275 million -- or is "low in quality," the stock will suffer "meaningfully," she wrote.
