2015 Top Stock Picks: SLCA, PRTA, LCI

Our 2015 top stock picks include a number of biotech stocks, an energy play, and one company that may be overheating.

Topping the list of our 2015 top stock picks include the biotech names Prothena Corp. Plc. (Nasdaq: PRTA) and Lannett Co. Inc. (NYSE: LCI). Up 80.8% and 56.7% respectively, these two companies show that the biotech stock sell-off a few weeks ago was merely a blip in a red-hot sector.

Crude oil prices are still weak – a function of increased U.S. domestic energy production – but that hasn't soured a stunning 51.8% gain for U.S. Silica Holdings Inc. (NYSE: SLCA). Silica provides specialized sand that props open cracks in rocks created through hydraulic fracturing. Without this sand, those cracks would close up and natural gas and oil would remain trapped.

One of our top performers may be sending out a signal that now is not the best time to buy, however. That stock, up 46.7% this year, is JD.com Inc. (Nasdaq: JD). We discussed the intrigue of JD stock last month as a competitor to Alibaba Group Holding Ltd. (NYSE: BABA). But this No. 2 Chinese e-tailer may well be overheating. And even with Alibaba stock struggling this year, JD is going to find itself fighting a difficult price war with Alibaba.
