Good topic JGPM , maybe a broker can shed light on ...I guess it’s got to do with naked positions

There are two types of short sale transactions: naked and covered. Broadly, a naked short sale occurs when a seller does not own and has not borrowed or arranged to borrow securities at the time of sale but intends to purchase or borrow stock in order to meet the delivery obligation. A covered short sale occurs when the seller has arranged to borrow the security in order to meet their delivery obligations prior to entering into the arrangement to sell the security. An investor will generally execute a short sale by requesting their broker to place a sell order on the market.

3.1 Type of reporting
As outlined in the background section, there are two types of short selling reporting: positional reporting and transactional reporting. Positional reporting involves investors reporting their overall short position (as a proportion of issued capital) in relation to a particular stock. It differs from transactional reporting because it takes into account transactions that close out short positions. For this reason, positional reporting may provide a more accurate indication of the bearish sentiment within a particular stock at any point in time and also the amount of overhang in the stock that will need to be covered at some point by short sellers purchasing shares. In addition, for investors, this information may provide an indication of the level of risk involved in shorting the stock, particularly if total aggregate short positions are made available. For example, it may be risky for an investor to take a short position in a particular stock if a significant proportion of that stock has already been shorted. This is because there is a greater chance of being subject to a ‘short squeeze’ if market sentiment changes and the investor is required to close out its position in a short period of time. A number of countries (including the US, UK and many European countries) have adopted reporting requirements for short positions.
On the other hand, transactional reporting involves the reporting of the value of all short sale transactions in a particular stock during the day. As outlined above, the interim ASIC disclosure requirements are based around transactional reporting. They provide an indication of the proportion of trades in a particular security that are short sales and the overall level of short selling that takes place on the ASX each day. This assists investors and companies in explaining share price movements. For example, if a company’s share price is particularly volatile, interested parties are able to refer to the transactional short selling information to gain an understanding of whether there has been an increased level of short selling activity in the stock. This information is also useful for regulators in carrying out market surveillance and investigating alleged cases of market misconduct. This is because the information is likely to be more detailed than positional information, as it identifies individual short sale transactions. Regulators can use this information as an audit trail when conducting investigations.
