Same as Shorting below. A transaction whereby an investor borrows stock from a shareholder for a fee and with a guarantee to return theequity at an agreed later date. In theory, the borrower is anticipating a decline in the share price, which will allow them to benefit from the differential between the price at which they sell the borrowed stock and the price at which they repurchase it. For spreadbetters, it is selling the hope that the stock will decline. The trade is then closed by buying – the’long’ – to balance the book.
