Groupon Inc shares surged more than 20 percent as traders scrambled to close bearish bets ahead of first-quarter results from the largest daily deal company, due later on Monday.
The gains are driven by "short covering and anticipation that the results are not going to be terrible," said Jeff Houston, an analyst at Barrington Research.
"This should be the first quarter that they report a profit, on a pro forma basis," he added. "If that happens, it will be an important milestone for Groupon."
