AMC Entertainment Holdings, Inc (NYSE:AMC) and GameStop Corporation (NYSE:GME) were flying 10% and 16.5%, respectively, in after-hours trading on Tuesday but on Wednesday when the market opened most of the surge was subdued due to a 0.41% lower open for the S&P 500.
Traders and investors quickly came in and bought the dip, however, and within the first half-hour of trading, AMC was up over 7% and GameStop was soaring over 15%.
