Answer: short selling
Explanation: In simple words, short selling refers to the process in which an individual borrows stock from its holder with the promise of giving it back after a specific time and at a specific price, after borrowing he or she sells the stock at the current market price and expects that the price of stock will decrease in future.
The borrower then purchases the stock at a lower price and gives it back to the lender with the margin profit in his or her pocket. Short selling works like a speculation but only market experts do such activity due to high risk involved.
Such processes are of high value to the market as they result in creation of liquidity.
