# Short Interest

`GET` `/v1/short-interest/{ticker}`

Retrieve FINRA short interest history for a ticker: settlement date, short interest shares, average daily volume and days to cover. Data updates on the standard bi-monthly FINRA schedule. Use this to gauge short positioning, squeeze risk and sentiment relative to float.

## Use cases

- Short interest and days-to-cover screens
- Sentiment and positioning research
- Risk monitoring for heavily shorted names
- Pairing with float data from quotes for squeeze analysis
