Human Psychology, High Profile Covid-19 Cases and the Impact on Sentiment

In continuation with our write up of 10th March 2010, we have some interesting insights on how the local country by country sentiment on Coronavirus news flow has evolved and how it is linked to the performance of local stock markets. There are some clear takeaways on this;

  • On a time series for the countries individually, you notice huge fluctuations in Coronavirus sentiment. In some cases (of which USA is the most prominent), the news flow sentiment has deteriorated rapidly.
  • The same is the case with Canada in which the Coronavirus news flow sentiment has deteriorated sharply. But the reasons are perhaps different than US. In Canada, this could be because of a high-profile case of infection (Prime Minister’s wife).
  • The huge volatility noticed in the markets such as US is linked with rapid deterioration on one side and the policy announcements on the other. If left to Corona alone, things could have been much worse.
  • India is an interesting case because after the ‘V’ shape recovery in sentiment, the news flow has deteriorated but at a rate which is not rapid. This reflects in sharp recovery in markets as noticed in Friday’s trading session.
  • The variance between countries on day to day basis continues (for example, Japan is the country with the most NEGATIVE sentiment on the basis of news flow for 14th March) and while things look much better for Korea, Chile and Brazil.
  • All of this leads to the question: Can the sentiment analysis be used for taking a short term call on markets? And the answer is a resounding YES. As shown in the Chart 3, the portfolio incorporating Coronavirus sentiment does significantly better vs. BSE Sensex.
