Why timely short interest data matters

Timely and precise short interest data is essential for assessing risk, market sentiment, and trading behaviour.

The Short Interest dataset delivers real-time, high-confidence short interest insights, providing a significant advantage over delayed official exchange reports.

Utilizing an advanced methodology, the dataset applies a proprietary model to refine short interest estimates, filtering out non-shorting-related lending activities to ensure cleaner, more accurate data.

Available identifiers include ISIN, FIGI, Share Class FIGI, MIC, Operating MIC, Ticker, and Company Name.

Methodology backed by machine learning

A proprietary machine learning model refines short interest estimates using securities lending data. It filters out non-shorting activities such as settlement certainty, market making, collateral, balance sheet maintenance, and dividend arbitrage.

By incorporating official exchange short data, the model achieves 97% accuracy in predicting exchange-reported short interest.
