I follow short-selling data for two reasons. One, to know which Australian companies are in the bears’ sights, understand why and test their view against the bullish case.
Two, to identify positions that look wrong, knowing that good company news will force short-sellers to buy back the stock to cover an open short position, or close it out and book losses.
For the uninitiated, short-selling involves the sale of a security the short-seller has borrowed. When someone is “short” a stock, they expect its price to fall. For example, a trader borrows 1,000 shares, sells them at $30 and buys them back at $25, pocketing the difference.
