Why Did Trivago Stock Jump 20% on Thursday?

Shares of online hotel-search platform Trivago (NASDAQ: TRVG) rose as much as 20.7% on Thursday. The stock is up about 17% at the time of this writing.

There doesn't seem to be any material news driving the stock's move, as there were no company press releases or SEC filings on Thursday. But the stock's sharp increase does follow a significant pullback in its share price recently, suggesting the stock's gain could represent some investors potentially trying to take advantage of the lower stock price.

Or, here's another possible reason: Trivago stock's short interest is up considerably from where it was at the beginning of the year, suggesting some investors may be covering their short positions after the stock's huge slide, creating a short squeeze.
