(Reuters) - Andrew Left, the founder of Citron Research, is again betting against retail investors' favorite GameStop, which is back in the limelight after super-bull "Roaring Kitty" Keith Gill resurfaced online following a three-year hiatus.

Citron was forced to close its short position in GameStop at a loss in 2021, after retail traders ganged up against heavily shorted stocks on online forums to drive rallies, which cost bearish investors billions of dollars.

"It's fun to go back into the fire. The market dynamics have changed and I'm not as exposed as I was," Left told Reuters on his current position in GameStop.

"The first time, three-and-a-half-years ago, (GameStop) was a cultural phenomenon, and that's played out by now. The company has deteriorating financials and is a good short."
