Wall Street has been consumed this week watching a real-time battle unfold between retail investors and hedge funds over formerly moribund stocks like GameStop, AMC Entertainment, and BlackBerry.
Using social media posts and Internet chat rooms, retail investors utilizing trading apps like Robinhood and E*TRADE sent the stocks soaring. GameStop’s value mushroomed from $2 billion to $24 billion in the space of a week, only to come tumbling down Thursday after several trading platforms began to limit trades on the stocks.
