# ShortInterest.au

> Free ASX short-interest rankings and company histories from ASIC outstanding short-position reports.

ASIC outstanding positions are generally delayed T+4. ASX daily gross short sales are a separate measure, generally T+1, and are not outstanding positions. Always cite the displayed source trade date rather than the retrieval date. Percentages use reported securities on issue; changes are percentage points. Missing values are unavailable, not zero. Rankings include ETFs, debt and stapled securities. Data is for research, not investment advice.

Markdown is available using the links below or Accept: text/markdown on the corresponding homepage, top-100, ticker and informational page URLs. Markdown requests redirect to the explicit .md URL. HTML remains the default. Ticker Markdown includes a one-year window of loaded ASIC position dates. Never infer coverage for unlisted dates.
