Short Selling: How, When and Why You Should Short Sell
What is “short selling” and how does it work? The concept of short selling is often seen as something immoral or alarming to many traders. Traders often assume that because mutual funds and financial planners go long, it is more correct to do. When you short sell you are actually borrowing a stock at a fee, and selling it on the market. At some point the trader “covers” his sale by repurchasing the stock at the current market price, and returning the shares to the lender. If the price is lower the short seller makes a profit, else he makes a loss.
