The Double Helix application is the key analytical tool that powers our Equity Optimiser service. It maps millions of corporate news items against billions of stock price movements to quantify the impact of media issues and coverage on the shareholder value of companies. Combining our proprietary natural language engine with media aggregation and stock market information, the tool computes the cumulative and periodic abnormal return of the shares of the analysed companies in respect to taxonomized and custom price driver issues.
