Investing.com -- GameStop Corp (NYSE:GME)and AMC Entertainment Holdings Inc (NYSE:AMC) aren't the only stocks soaring on Wednesday even as the Dow Jones Industrial Average sheds 300 points.
BlackBerry Ltd (NYSE:BB) jumped 24%, to above $23, Koss Corporation (NASDAQ:KOSS) jumped 222%, to $32.25, and Express Inc (NYSE:EXPR) rose 247%, to $10.57, all seemingly part of a short squeeze pitting professional and retail traders against each other.
There isn't much else to explain the big gains in these stocks. The volatility forced exchanges to halt trading in the stocks several times on Wednesday, and trading activity also picked up in the options around these names.
