Why Westport Fuel Systems Stock Jumped 10% on Wednesday

Shares of Westport Fuel Systems (NASDAQ: WPRT) stock exploded as much as 10% higher on Wednesday before finally closing the day up a still respectable 9.7%. That's pretty amazing -- but here's the really crazy thing:

There doesn't seem to have been any reason whatsoever for the stock going up so much. No analyst upgraded Westport stock yesterday. The company didn't report earnings, and in fact issued no press releases of any kind. For that matter, Westport last reported earnings two months ago, which means we don't expect to get any more earnings news out of the company for about another month.

If enough people pull together, a stock can go up for no reason at all. Image source: Getty Images.
