Sentiment and Investor Behavior

Using Refinitiv News Analytics over monthly horizons, Refinitiv analysts consider what trailing news sentiment means for investment returns. 

Taking into account post-earnings announcement drift and the pricing of beta portfolios, Refinitiv analysts look at how trailing news sentiment can be incorporated into investment strategies.

It is well understood that large swings in price, volume and volatility can occur on the initial reporting of extreme sentiment news stories. Markets react quickly to new information, however, and any initial reaction can be difficult to profit from for all but the lowest latency investors.

We can consider whether or not the market generally underreacted or overreacted to new information and whether to expect price drift or reversion in the coming hours, days or weeks.
