Clean Energy Fuels (NASDAQ:CLNE) has jumped more than 7% during trading over Tuesday and Wednesday as investors applaud two major catalysts for the stock.

For one, CEO Andrew Littlefair just purchased 127,000 shares, valued at approximately $1.6 million. Investors always like to see management with skin in the game, so to speak. It's a vote of confidence in the company and also aligns CEOs with shareholders' interests.

Additionally, the company announced a joint venture with industrial giant General Electric (NYSE:GE) to develop liquefied natural gas projects throughout the United States. Motley Fool analyst Taylor Muckerman appreciates the CEO's display of confidence, and sees the deepening relationship between GE and Clean Energy Fuels as mutually beneficial. However, Clean Energy Fuels has a bumpy history and has underperformed the market for years. Taylor likes this stock despite its volatility, and believes this stock is a long-term energy play.
