From the Document: "Video game chain GameStop triggered a market frenzy in early 2021 when its stock price rapidly increased from around $18 to well over $400 in intraday trading. The developments soon spread to some other stocks and markets. The episode raises several policy issues, including social media's influence over investment decisions, zero-commission trading, short selling, investor protection, market functionality, and financial stability."
