Recent price: $4.81 Back in January, I predicted this maker of education-oriented toys was poised for a good year. In subsequent months, the company failed to deliver on the promise I foresaw, so its share price moved in the opposite direction I had anticipated. Yet just-released quarterly results were nothing short of a blow out, and a fresh stock surge has moved it up more than 10% from where I originally recommended it. Further upside looks quite possible. That's because Leapfrog's LeapPad, a sort of iPad for toddlers, is finally gaining serious traction (though device-specific sales weren't divulged). This fueled a 9% year-over-year gain in third quarter sales to $151 million, and earnings per share (EPS) of $0.35 were nearly 30% ahead of forecasts. Yet it's the all-important holiday season that could lead to a stock breakout. As analysts at Needham note, the $100 LeapPad's "camera and internal memory give it a strong advantage over competitors' products, as does its strong library of apps and the pedigree of the Leap Frog brand." They see shares trading up to $6.
