Where can I find the ASIC daily short position report?

ASIC publishes daily short position reports on its website at asic.gov.au under the 'Short selling' section. The data is also available via the ASX website under market data. Shorted.com.au provides the same ASIC data in an easier-to-use format with charts, historical trends, and search functionality.

What columns are in the ASIC short position CSV file?

The ASIC CSV file contains five columns: DATE (the reporting date), PRODUCT (full company name), PRODUCT_CODE (the ASX ticker such as BHP or CBA), REPORTED_SHORT_POSITIONS (number of shares held short), TOTAL_PRODUCT_IN_ISSUE (total shares on issue), and PERCENT_OF_TOTAL_PRODUCT_IN_ISSUE_REPORTED_AS_SHORT_POSITIONS (the short interest percentage).

How do I find short sale transaction data on the ASX website?

The ASX publishes a daily Short Sales report under its Market Activity section. This shows individual short sale transactions executed on the exchange each day. For aggregated short position data (which shows total outstanding short positions), refer to the ASIC daily short position report instead.

Is ASIC short position data available in real time?

No. ASIC short position data is published with a T+4 trading day delay. This means the data you see today reflects positions from four trading days ago. The delay is designed to protect the trading strategies of reporting entities while still providing transparency to the market.

How to View ASIC Short Position Reports on the ASX

Where to Find ASIC Short Position Data

ASIC publishes aggregated short position data for all ASX-listed securities every trading day. There are three main ways to access this data, each with different levels of usability.

Option 1: ASIC Website (Primary Source)

The Australian Securities and Investments Commission publishes short position reports directly on its website. To access them:

Visit the ASIC website and navigate to the "Short selling" section under market data
Select the date you want to view (remember the T+4 delay means the latest available date is 4 trading days ago)
Download the CSV file containing all short positions for that date

The ASIC data is published as downloadable CSV files. Each file contains one day's worth of short position data for every ASX-listed security with reportable short positions.

Understanding the CSV File Format

The ASIC short position CSV file contains the following columns:

DATE: The reporting date in timestamp format (e.g., 2026-02-05)
PRODUCT: The full name of the listed security (e.g., "BHP GROUP LIMITED")
PRODUCT_CODE: The ASX ticker symbol (e.g., "BHP", "CBA", "CSL"). This is the key identifier used to match stocks across different data sources.
REPORTED_SHORT_POSITIONS: The total number of shares reported as short across all reporting entities. This is the aggregated net short position.
TOTAL_PRODUCT_IN_ISSUE: The total number of shares on issue for the security, used as the denominator when calculating short interest percentage.
PERCENT_OF_TOTAL_PRODUCT_IN_ISSUE_REPORTED_AS_SHORT_POSITIONS: The short interest percentage, calculated as reported short positions divided by total product in issue, multiplied by 100.

Example Row

A typical row in the CSV might look like:

2026-02-05,BHP GROUP LIMITED,BHP,45230000,5012000000,0.90

This tells us that on 5 February 2026, BHP had 45.23 million shares reported as short out of 5.012 billion total shares on issue, representing 0.90% short interest.

Option 2: ASX Website

The ASX provides two related but different short selling reports:

ASX Short Sales Report

The ASX Short Sales report shows individual short sale transactions executed on the exchange. This is different from the ASIC short position report — it shows daily transaction volume rather than outstanding positions. You can find this under the ASX's Market Activity section.

Short Position Data via ASX

The ASX also makes ASIC's aggregated short position data available through its data platform. This is the same underlying data as the ASIC CSV files but may be presented in a different format.

Option 3: Shorted.com.au (Easiest)

Shorted.com.au ingests the same ASIC data daily and presents it in a more accessible format. Instead of downloading and parsing CSV files, you can:

Search by stock code: Instantly look up short positions for any ASX stock
View historical trends: See how short interest has changed over weeks, months, and years with interactive charts
Browse top shorted stocks: See the most heavily shorted ASX stocks ranked by short interest percentage
Filter by industry: Analyse short selling patterns across different market sectors
Weekly reports: Get automated summaries of the week's short selling activity including biggest movers

Tips for Working with ASIC Data

Always Account for the T+4 Delay

The data you see today reflects positions from 4 trading days ago. If significant news broke yesterday, it won't appear in the short position data for several more days. See our guide on Understanding the T+4 Delay for more detail.

Compare Over Time, Not Just Single Days

A single day's short position data is a snapshot. The real value comes from tracking changes over time. Look at trends over weeks and months rather than reacting to a single day's movement.

Cross-Reference with Other Data

Short position data is most useful when combined with stock price movements, trading volume, company announcements, and broker research. No single data source tells the complete story.
