Most shorted stocks reporting earnings this week


Many investors are hoping for their big bets to pay off this week with earnings beats, but others are wagering that companies will disappoint.

Swift Energy, an oil and gas company primarily working in Texas and Louisiana, is the most shorted stock reporting earnings this week—almost 39 percent of its shares outstanding are on loan, according to Markit. The stock is down almost 14 percent year-to-date, but is well above its lows from the beginning of March.

KEYW Holding, a cyber security firm that Reuters reports has worked with the U.S. government, is also heavily shorted—the second-most of any stock announcing earnings this week with 32 percent of shares outstanding on loan. Markit analyst Simon Colvin notes that KEYW's bears have stuck to their guns, driving up short interest to an all-time high despite the stock recovering off of recent lows.
