What is short selling in the stock market and how it works

In stock market, traders buy common stocks and then sell them at a higher price to make a profit. This type of trade is completed with a buy order and then followed by a sell orders. This means, if a trade is entered with a buy order, then it will be exited with a sell order. Short selling is opposite to this process. This means in it, a person takes a short position, if he expects that the price of the security will decline. In short selling the trader enter with a sell order after borrowing stocks from the broker and then exit with a buy order when share value comes down as expected.

Understanding short selling concept

When stock prices are expected to go up, you can benefit by buying stocks at the present level and then sell it later for a higher value. But, what happens when you are expected the stock prices to fall from the present level? In this case, if you have enough money, you can buy stock after its fall and then sell it at a higher level to make a profit.

What if you don’t have enough money to buy and sell that stock? In this type of situation, traders use short selling. Instead of buying and selling stocks, what these people do is that they borrow stocks from the broker and sell them at present market price to buyers willing to pay the market price in order to buy when price decreases.

The main reason for taking a short selling position is that you believe that the market price will come down in future. If it happens, you can buy stocks at a lower valuation and then return it to the lender. If it didn’t happen, you will be buying stocks at a higher valuation resulting in a loss for you. This means in short selling, traders are betting on the prices of a stock that it will drop in the future.

Here are the steps in short selling;

  • The trader borrows stocks from broker;
  • Sell those stocks in open market to get cash;
  • Wait for the stock to fall as expected;
  • Buy the stocks back from open market to return it to the lender


Suppose stocks of XYZ limited is overvalued and its price will drop due to market volatility. On the basis of this assumption, you place an order to sell short 1000 shares of XYZ limited at a price of Rs 400 per share by borrowing shares from your broker. Brokerage firm can either get these shares from its own inventory or from other brokerage firms. Now the brokerage firm in your margin account will show the value of shares you borrowed minus commission of the brokerage firm.The brokerage firm on the basis of your order sends these shares to a buyer. When stock of XYZ decline to a lower level, you put a buy order to cover your short position. Suppose you bought 1000 shares at Rs 350 per share, this means you made a profit of Rs 50,000 (Rs 50 per share) minus commission and interest charged on the margin account by the brokerage firm. 1000 shares that you borrowed from your brokerage firm is now returned.

Short selling are transacted in your margin account as protection in case you default on the short sale. On this we suggest you to contact your broker as they may charge interest on the value of the borrowed shares while the position is open.

If the stock’s price falls below its short sale price, you make a profit. On the flip side, if the stock’s price increases instead of falling down, you lose money. Your loss will go up based on the increase in market price of the stock.

In our above example, assume that the stock of XYZ limited has gone up to Rs 550 per share instead of falling down as per your expectations. In this case, you have to buy the stock at a higher level to cover your short position. If you bought XYZ limited shares at Rs 550 per share, then you are losing Rs 100 per share plus brokerage commission. This means, the higher the price, the greater the loss and lower the price, the greater the profit.

In short selling, you are not the owner of the securities as you have borrowed it from someone. Hence, the short seller is required to pay any dividends that are declared by the company to the owner of the borrowed securities.

How stop order can protect profit/loss in short selling

In stop order, you instruct the broker to buy or sell a stock after it reaches a specified price. After reaching the specified price, the order becomes a market order.

This type of order can be used to protect your profit or loss in short selling. Suppose you sell stock of XYZ limited at Rs 400 per share and the stock declined to Rs 380. Now you have two choices: you can either buy back the short position or wait for further decline to buy at a lower level. At this juncture, if you want to protect your profit against an unanticipated price hike, then you can place a stop order at Rs 385 to preserve profit of Rs 15 per share.

Similarly you can use a stop order to protect losses in an unfavorable short sale. In our above example, you can place a stop order at Rs 410 to limit your losses at Rs 10 per share.
