Accern used 600k articles in an event-driven sentiment backtest.

Hi guys,

We recently backtested over 600,000 news and blog articles related to company earnings (2.5 years length) with the help of Quantopian community members. The results are very interesting.

The purpose of the backtest was to identify the performance of trading on earning information in real-time and also to identify which segment of earnings information generated the most returns. We found that Financial Ratings (a segment of Company Earnings) generated the most returns. We also wanted to identify the effect and performance of Acquisitions, Corporate Governance (management decisions), and Contracts (deals, partnerships) on stock prices and how well these types of events can be used in quant trading.
