Emotions on the stock exchange and what comes out of it for investors

Emotions on the stock exchange. Can investor sentiment be measured? Yes, currently it is done on the basis of surveys (e.g. AAII Bull and Bear), a set of complex measures (Fear and Greed index) or an analysis of buying trends (Investor Sentiment Index). The latter means predicting the actions of stock buyers on the basis of … these actions, not an external indicator. And is it possible to measure emotions on the stock market and what does that mean? You will find out from the following article.

Research to date on the use of sentiment in forecasting stock market indices

In December 2018, the publication “Media Sentiment and International Asset Prices” appeared, published by the National Bureau of Economic Research, in which the authors analyze Reuters’ and Bloomberg’s articles in terms of their impact on major stock exchange indices. Researchers discovered interesting relationships between sentiment in the articles and index values, such as for example:

  1. The first mood of the news correlates 4x more strongly with the bear market (dominated by declines) than during the bull market boom,
  2. The second mood index is a much better reflection of the behaviour of world indices than the commonly used VIX (CBOE Volatility Index),
  3. and the positive mood in the media has a more positive impact on the developed markets.(but negative on the emerging markets).

Unfortunately, none of the approaches allowed for forecasts to be more than 55-60% accurate. This is probably not possible based on sentiment or emotional tags offered by social networking platforms like Twitter or Facebook.
