Capital Research Global Investors now owns a 10.1 percent stake in Yahoo, according to a new SEC filing. Even Silicon Alley Insider is stumped as to why Capital Research chief Gordon Crawford, who fought to get rid of Yang last year, would be buying more YHOO. I go with Owen's theory: It's simple dollar cost averaging. When Yahoo falls to $13, buy it. Regardless of who's in charge. (Photo by AP/Douglas C. Pizac)
