In our trading portfolio, we usually increase our short position in market futures just before the earnings season starts. As you know, the market often overreacts to perceived negative news, especially when companies report earnings. These situations create single-stock liquidity gaps, and we want to take advantage of them when the odds favor a quick return to more normal prices. Having a short market position in our back pocket helps us exploit the liquidity gaps without increased market exposure.
In these setups, assessing the degree of overreaction is paramount.
