The process of borrowing securities for the purpose of trading is considered one of the investment deals developed in the stock market that keeps pace with the development of trading operations. This process of trading contributes greatly to stimulating the movement of securities continuously and effectively, because it includes several operations within its scope, as it is not limited to one transaction, but rather a reason for various transactions from the process of loan, sale, repurchase, and then redemption. Therefore, this method is one of the most stimulating trading methods for the movement of trading in the market, as it includes a professional investor in the market operations and the price fluctuations that occur. When the price is expected to drop for any reason, she seeks to borrow these securities to sell them and then repurchase them when a profit decreases, and then return them to the lender with the profit of the borrowing. Thus, this achieves the interest of both parties, but these expectations may come with counterproductive results that have dire effects, so this permission to invest in this process requires legislative regulation and the supervision of competent authorities in the market that settle this process, in order to ensure good implementation and protect dealers and the market from the disturbances that result from poor implementation and poor organization. Consequently, the present study is trying to explain these points to put a successful investment method that is organized and a mechanism that is not complicated and with simplified guarantees that we benefit from its positive and fruitful results and avoid the possibility of achieving its negative returns
