Plus, inflation and record-high mortgages will likely result in less savings and money for investors to spend on stocks, especially on two risky, cash-burning businesses like GameStop and AMC. Movie theater operator AMC Entertainment Holdings (NYSE: AMC) also rose in January 2021, but it didn't hit its peak until the summer, when its shares hit a high of $72.62 on June 2. Today, GameStop and AMC shares are trading at $105 and $16, respectively.
