Besides GameStop, Robinhood said trading in stocks such as AMC Entertainment, Bed Bath & Beyond, Blackberry, Nokia, Express Inc., Koss Corp., American Airlines, Tootsie Roll, Trivago and Naked Brand Group would be affected by the new restrictions. Interactive Brokers also placed option trading of AMC, BlackBerry, Express, GameStop and Koss "into liquidation," citing extraordinary volatility in the markets. The company has forced huge, ground-shaking changes for the brokerage industry, such as its decision to charge zero commissions for customers trading stocks and exchange-traded funds. The recent surge in GameStop has been the product of a tug-of-war between small investors and some big institutions. But there is some concern that small investors could face significant losses when and if stocks like GameStop plummet.
