The Strategy

We backtested a mean reversion long-only strategy from February 2016 to August 2016 using Accern’s historical news and blog dataset. We used the following metrics in our backtest: article_sentiment, event_impact_score_entity, and overall_source_rank.

We filtered the historical data to look at articles with:

  • article_sentiment < -0.20
  • event_impact_score_entity > 80
  • overall_source_rank > 6

A weight multiplier was then applied to articles that matched the filtered criteria:

  • event_impact_score: power of 33 (multiplies 33 times)
  • article_sentiment: power of 12 (multiples 12 times)

The scores were then normalized so they added up to 1. The larger the score, the more shares we bought.

We conduct a backtest using daily, weekly, and monthly holding periods. The results differed based on holding periods.
