3 Big Winners This Week

In the following video, Fool.com contributor John Reeves takes us through three stocks that have shown investors big jumps this week. He discusses Netflix , which is up 11% for the week and nearly 100% for the year, and says this most recent pop may be due to the possibility that Netflix will be added to the Nasdaq 100, made more likely by Dell's departure as it plans to go private. John also talks about the 3-D printing world and tells us about 3D Systems , up 13% this week after announcing a three-for-two stock split. Both this stock and its only publicly traded competitor, Stratasys , soared in 2012, leading some investors to see them as a bit frothy. Lastly, John talks about Westport Innovations , maker of natural gas engines. The company has experienced a lot of volatility this past year, but is currently up 7% this week on news that it and its partner Cummins will be supplying engines for two of the largest transit fleets in the U.S.

As the most advanced designer of engines powered by natural gas, Westport Innovations is a small company with a big goal: To lead the world in transitioning from traditional oil-based fossil fuels in favor of abundant, cheap, and clean natural gas. The company has a price tag large enough to match its ambition, and will need to grow revenue quickly in order to justify sky-high expectations.
