Short Selling

Short Selling information is available for ASX and CXA shares.

The data is sourced from ASIC and ASX on a best effort basis. Their reports are published at different times in the morning and those times vary.

Spark updates within 5 minutes of a report being published.

ASIC

ASIC publishes a report of the total number of shares that are held short per stock every morning.

The report is for 4 trading days ago.
It is usually published around 11:30am.
It is sometimes updated with corrections during the day.
The shares issued figure is known to be sometimes incorrect.

ASX

ASX publishes a report of the number of shares traded short per stock every morning.

The report is for the previous trading day.
It is usually published around 11:00am.
It includes both ASX and CXA short trades which may cause confusion when not consolidating.

Shares Issued

Sometimes there is a discrepancy between the shares issued figure that ASIC publishes and the one that ASX publishes.

Spark has a preference to control which figure to use to calculate the percent held short.

Choosing to use the ASX figure will give a more accurate percentage, but the ASIC percentage may be more commonly used.

General Accuracy

The data is sourced from ASIC and ASX and provided as is.

When you mouse over a short selling column, the tooltip shows the following:

% Held Short

The main table shows the change in % held short over time:


Latest date	Latest % Held Short
Date before latest	Prior day's % Held Short	Change in % held short between the last 2 reports
Prev Week	% Held Short 1 week ago	Change in % held short from last week to the latest date
Prev Month	% Held Short 1 month ago	Change in % held short from last month to the latest date
Prev Year	% Held Short 1 year ago	Change in % held short from last year to the latest date

The Prev Week, Month, and Year columns are relative to the date of the most recent ASIC report, not the current date.

The far right column visually shows the proportion held short on that date.

Short Traded Vol

This is the ASX reported total volume traded short on the most recent day for which data is available.

Days to Cover

Shares Issued is the shares issued figure on the most recent day for which ASIC data is available, according to your preference.

Net Held Short is the ASIC figure on the most recent day for which data ASIC is available.

Avg Daily Vol is the average volume traded on market calculated over the past week from the current date, as used in Spark's relative volume figures.

Days to Cover is the number of days it would take to buy back the total number of shares held short at the average daily volume.

Note that the data may change at any time after ASIC or ASX update their report.
