CNNMoney: Wall Street is throwing in the towel on Yahoo. It seems that investors have no faith in the company’s turnaround efforts under CEO Marissa Mayer. Shares of Yahoo are now trading around $30, just 3% above the 52-week low that it (and many other stocks) hit during the height of the market’s panic on Aug. 24. That’s bad news. All of Yahoo’s peers have rebounded sharply from the fear-induced lows.
