This study provides a methodology to track companies moving in or out of the
media spotlight to help predict stock price direction.
Abstract:
This paper shows that an investor evaluating a universe of stocks should
be concerned about tracking media coverage and sentiment. The concept of
abnormal news liquidity is introduced and is demonstrated to predict long-term
price direction when distinguishing between companies moving in or out of the
media spotlight. Specifically, this paper shows that when companies moving out
of the media spotlight are portrayed positively in the news, they tend to
outperform the market over the following year. Likewise, companies that are
portrayed negatively tend to significantly underperform the market. For
companies moving into the media spotlight, the market tends to either over or
underreact to positive and negative news sentiment depending on market
conditions.
