#8: Yahoo (YHOO)
Yahoo (YHOO) is another stock that was languishing at the end of last year but is sitting pretty at the end of 2013. The company was roundly criticized for poor U.S. operations, declining ad sales and serious challenges in the age of social media and mobile web browsing. But Marissa Mayer went on a buying spree, snatching up two dozen stocks in 2013 including the buyout of video startup Ptch just a few weeks ago.
Investors also cheered the fact that YHOO managed to post its first year-over-year revenue growth in four years. Of course, the biggest catalyst for Yahoo stock wasn’t any of these domestic moves at all, but rather a stake in the fast-growing Asia internet company Alibaba. If and when Alibaba goes public in 2014, YHOO’s 24% stake in the company will result in a mammoth payday — and likely a special dividend to shareholders, if reports are right.
