It’s common knowledge that the faster you hit a baseball — all other things being equal — the more it’s going to fly. By the same logic, market behaviors can be forecasted by studying the response to certain impacts. For example, a routine HR announcement probably isn’t going to move the needle as much as a massive earnings beat and guidance hike.
Further, it stands to reason that traders mostly base their acquisition and distribution decisions on what has materialized in the immediate past. For example, volatility usually begets more volatility. Still, at some point, the red ink becomes so extensive that the affected security starts to look like a discount.
