Provided that SEC Reg SHO requirements are met, short sales in themselves do not violate any SEC or FINRArules. Were there any SEC or FINRA Rule violations? As volatility of stocks like GameStop have risen dramatically, DTCC is now requiring 100% collateral on the settlement of these stocks. Clearing Brokers therefore require firms like Robinhood to post collateral with them. All street-side trades received by the Clearing Broker for all its clients are compared and netted in the clearing system, resulting in a single net settlement on settlement day at DTCC.īecause of the risk that a broker (or a Clearing Broker) might go bankrupt between trade date and settlement date, DTCC requires Clearing Brokers to post collateral based on the volatility of the securities being settled. The retail investor trade is executed on an exchange, and the Clearing Broker also has responsibility for settling the exchange or “street-side” leg of the trade. Provided the investor has sufficient cash in his/her account on settlement date, the Clearing Broker is required to deliver securities to the investor’s account. Purchase (and sale) trades done by retail investors through brokers such as Robinhood, are “given up” by the online broker to a Clearing Broker. There may well be fewer lenders willing to lend at the higher price level and the stock “trades special” at higher fees.

This article outlines the credit risk and settlement mechanics underlying these events, and outlines potential regulatory issues. Once retail customers were allowed to resume trading, GameStop and other stock prices rebounded sharply. Robinhood raised $3.4 billion of additional capital from its investors, and was able to resume new trading activity. Note: GameStop and similar stocks fell 44% on Thursday 01/28. As a result- Robinhood and other firms had to curtail trading. Responding to the high volatility in these stocks, on Thursday 01/28 the Depository Trust & Clearing Corporation (DTCC), put up the collateral required for member firms to clear trades, to 100% of the market value of the trades.

Note: Melvin received a $2.75bn of new capital from Citadel and others on Thursday. This causes the Hedge Funds to book losses on their short positions and have to put up more collateral to support the trades. Reddit forums such as WallStreetBets mobilized day traders and retail investors to aggressively buy these stocks. Hedge Funds such as Melvin Capital reportedly have large remaining short positions of $11.7bn in these stocks (estimated 136% of GameStop’s market value for example) after having already lost $19bn in the past few weeks.
