# Delayed Reported Short Interest

`GET /api/v1/stock/official_short_interest`

Retrieve Official short interest data for US, Canada, Australia and Hong Kong for a given stock ticker. Short interest is the count of shares sold short that remain open (not yet bought back), offering a window into positioning and crowd sentiment. Elevated short interest can reflect bearish conviction and, in some cases, set the stage for short-squeeze dynamics.

**Use Cases:** Market sentiment analysis, short-squeeze monitoring, risk management, trading strategy tuning.

### Available Data Points:

*   **Short Interest:** Total shares reported as short.
*   **Days to Cover:** Computed as short\_interest ÷ avg\_daily\_volume, estimating how many trading days are needed for shorts to cover. For display and risk flags, values below 1 are rounded up to 1.
*   **Avg Daily Volume:** The stock’s average daily trading volume over a defined lookback, used to normalize short interest.
*   **Settlement Date:** The official reporting/settlement date tied to the exchange calendar for this short interest snapshot.

### Coverage:

*   United States (US)
*   Australia (AU)
*   Canada (CA)
