Having seen Westport Innovations (NASDAQ: WPRT) jump more than 40% in the past month despite low oil prices hitting demand for the natural-gas engines it builds for key partners like Ford Motor Company (NYSE: F), investors were eagerly awaiting the company's fourth-quarter and 2015 results to understand whether the stock could continue to rally. Unfortunately, Westport Innovations has left investors in the lurch by missing earnings estimates and postponing its outlook for 2016 until the completion of its merger with Fuel Systems Solutions (NASDAQ: FSYS) later this month.
The growing uncertainty has raised an important question: Could catalysts like the recent surge in Westport's sales from its joint venture with Cummins (NYSE: CMI) help it turn around, or is the loss-making company on the verge of collapsing? Should you jump in, or dump Westport Innovations stock? Find out the answer in the following slideshow.
