Earnings Releases can result in large favourable moves in a stock's price; they can also result in a significant negative move in a stock's price often without any opportunity to exit the trade as it moves against you. We may double the margin requirements on specific stocks prior to these releases. This is a preventative measure so that traders will not fall to a negative equity.
