GameStop

GameStop appears in EP90 从美加墨世界杯看懂期权—华尔街的终极武器 as the episode’s main case for options as an offensive market weapon. The company is presented as a heavily shorted U.S. game retailer whose stock became the center of retail-trader coordination, call-option buying, short covering, and dealer hedging in 2021.

The source treats the case less as a business-quality story and more as a market-structure story. Gamma Squeeze, short interest, internet coordination, and trading-platform restrictions are the mechanisms that made the price move extreme.
