I determine this by: A press release or news update is a form of communication used by public companies to convey their message to stakeholders. This message often includes progress, updates, forecasts and on-going concerns that may need to be expressed. Therefore, releases by public companies are viewed as catalyst to further determine the current and future direction the company is moving – thus helping to move the stock in a positive or negative direction.
The stock was going to be down today without one of its subsidaries releasing an update. So, no need to "waste" it today when the company and IR could have savd it as a catalyst in a few trading days.
