Why it's happening:Much like yesterday, there is no specific news about Westport Innovations. However -- and this is unlike yesterday -- oil prices are up while natural gas is down, so there could be some trading based on the potential for Westport to benefit from that spike in oil. Another likely cause? The percentage of shares held short -- while down relative to most of 2014 -- climbed in January,so today's price jump might be at least partly being driven by short-sellers looking to exit their positions. The old "short squeeze," as it were.
For long-term investors, the price volatility of Westport shares will remain detached from the business while speculation rules the market. Factor in a market cap that just got back above $300 million today, and there's probably going to be plenty more days like this -- in both directions -- until Westport can get its house in order.
