Sentiment Analysis, COVID-19, and Pharma/Bio-tech Stock Prices

Information and Price Dynamics brings Natural Language Processing (NLP) to financial news and social media. We capture business news headlines and Twitter conversations to gain leverage on events affecting stock prices and investor sentiment. These text features are transformed into indicators which are combined with and improve forecasts of high and low stock prices through machine learning algorithms.

Advantages include:

  • diverse data feeds can measure both opinion and events,
  • cutting edge methods can more efficiently extract textual information from financial news sources
  • machine learning techniques can integrate news/sentiment analysis with forecasts of price volatility.

We extract information using topic modelling, identfying event ensembles within the time-shifting content of the news environment.

We combine variables built from text-based features with price forecasts already shown to outperform “no change” predictions. This supports multi-day price range forecasts valuable for options trading.
