What is Short Delivery?
Equity delivery based trading in India works on a T+2 rolling settlement cycle. What this means is that when you buy shares on, say, Monday (also called T day), you get the shares on Wednesday (T + 2 day). Similarly, if you sold the shares on Monday, you are required to give delivery of the shares on Wednesday after which you will get the proceeds from the sale (cash) to withdraw on Wednesday (T+2 day).
Let us take an example, you bought 100 shares of Reliance on Tuesday, September 3, 2013 at Rs. 800 and the seller of these 100 shares was Mr. X (although in the markets you don’t get to know who you have bought it from). On T+2, i.e., Thursday, September 5, you will get delivery of the stock to your demat account and Mr. X will get the sale proceeds equivalent to Rs. 80,000 (800*100).
But what if you had one of the following situations on hand:
1. What if you don’t have Rs.80,000 in your trading account to buy the 100 shares?
An exchange doesn’t directly interact with a client. When you as a client make a purchase of any worth, the exchange debits the money from the brokerage firm’s account that you are trading with. So if a brokerage has let you buy stocks for delivery with no money in your trading account, then the brokerage is obligated to pay for these purchases to the exchange. The broker would then recover the money from you and would also charge you an interest for the money that he has paid on your behalf to the exchange if you delay in payment.
2. What if Mr. X doesn’t have the 100 shares in his demat account, but he still sold them?
As mentioned earlier, if you sell any stock on T day, you are obligated to deliver the shares on T+2. But sometimes it may so happen that you sell some stocks but these stocks are not present in your demat account and hence you would not be able to give delivery of these stocks on T+2 and would end up defaulting. This default is called “Short Delivery“.
Now you’d be wondering how/why anyone would sell a stock and not deliver it? Well it can happen for various reasons. Here are a few common ones:
a) You sold 100 shares of Reliance for intraday expecting the price of Reliance to go down. If you sell any stock for Intraday you are expected to buy it back by the end of the day to close your position. Now assume you forgot to buy it! Now you’re left with no option but to deliver these 100 shares of Reliance on T+2. Since you don’t have any shares, you would not be able to deliver and would default, thereby causing a Short Delivery.
Now this cannot happen with your broker as Zerodha is because we let you buy/sell equities with 2 product codes: MIS (for Intraday) and CNC (for Delivery). All Intraday trades (bought/sold with the product code MIS) would automatically get squared off at 3:20 pm ensuring that even if you have not squared it off yourself the system does it for you. When you try to sell Reliance with the product code as CNC, the systems will check if you have these shares in your demat account and let you sell only if you do, thereby ensuring that there is no short delivery.
b) You sold 100 shares of Reliance at Rs.800 for intraday expecting Reliance results to be bad. However, news was out that Reliance had done exceptionally well and hence the stock went up and hit the upper circuit at Rs 880 (when a stock hits the upper circuit there are no sellers, so if you’ve short sold the stock, there is no way that you can buy it back unless it gets released from circuit. This won’t happen on a stock like Reliance but can happen on a lot of illiquid stocks that don’t trade on Futures and Options). Assuming the circuit is never released during the day, you’d be forced to hold your short position and would have to deliver the shares, failing which the shares would be short delivered.
The role of the Exchange is to ensure that if you buy shares, you get credit of the shares. Assuming you buy 100 shares of Reliance from Mr. X and if Mr. X fails to deliver these shares to the exchange on T+2, it’s quite obvious that you would not get these shares. So what happens is the exchange conducts an Auction and buys these shares for you in the Auction market and gives delivery of these shares to you on T+3 (Friday, September 6) instead of T+2.

What happens in an auction market?
In the Auction session, the exchange invites offers from fresh sellers for quantities short delivered (100 shares of Reliance in the above case)
When does the Auction happen and who can participate in the Auction market?
It is a special market where only members of the exchange can participate as fresh sellers and sell shares which are short delivered. The Auction market is conducted every day between 2:00 and 2:45 pm. To make sure that there is no conflict of interest, the exchange doesn’t allow the member whose client has defaulted in delivering to take part in the Auction market.
At what price are the shares sold?
There is no fixed price for the Auction to happen. The exchange specifies a range within which the auction participants can offer to sell their shares.
Upper cap of the range: 20% higher than the price that it closed on the previous day of the Auction.
Lower cap of the range: 20% lower than the price that it closed on the previous day of the Auction.
So in the Reliance example above, a fresh seller can offer to sell 100 shares of Reliance in the Auction market in the range of 664 (assuming Reliance closed at Rs.830 the next day; 20% below 830) to Rs.996 (20% above 830).
Coming back to the example, you bought 100 shares of Reliance from Mr. X at Rs.800 and Mr. X defaulted in giving you the shares. The exchange will now buy these 100 shares in the Auction market and give it to you.
Assume that in the Auction market the fresh seller is offering to sell 100 shares at Rs. 920 only. What now?
The Exchange is obligated to buy it at whatever price and give delivery of these shares to you. The Exchange would hence buy these shares at Rs.920/- and give you the shares. Since Mr. X has defaulted he would have to pay the difference of Rs. (800-920)*100 = Rs. 12000/- to the exchange. Along with this, the Exchange also charges an additional penalty of 0.05% of the value of stock per day that Mr. X failed to deliver. The sum of both the above together is called “Auction Penalty“.
So, typically, in the books of accounts of Mr. X, he would have received a credit of Rs. 80, 000 (800*100) as sale proceeds, and since he failed to deliver the debit on his account would be Rs. 92,000 (920*100) thereby resulting in a loss of Rs. 12000/- on the transaction.
Hence it is very important that you short sell a stock for delivery only if you have it in your demat account or you could lose up to 20% of the value of the stock as an Auction penalty.
The entire process:
a) On T Day Mr. X sells the stock.
b) On T+2 Mr. X fails to deliver the stock.
c) On T+2 when the shares are not delivered, the exchange blocks a sum of money from the brokerage’s account which is called “Valuation Debit”. The Valuation Debit is the closing price of the stock on the day preceding the Settlement day (basically, closing value of stock on T+1, as settlement happens on T+2).
d) On T+2, the exchange conducts the auction and purchases the stock from the auction participants on behalf of the defaulting seller.
e) On T+3, the exchange gives the shares to the buyer and sends an Auction note to the defaulting broker. The broker then passes on such auction charge to the defaulting client.
What happens if, on Auction day, the price of the stock comes down considerably? Can a client benefit in an Auction market?
An interesting scenario:
Assuming that after Mr. X sold the stock (at Rs. 800) the price of the stock dropped to Rs. 780 (on T+1). The valuation debit that would be debited from the brokerage’s account would be Rs. 78000/- (780 closing price on T+1 * 100 shares).
On T+2 the Exchange conducts the Auction and in the Auction market buys Reliance at Rs.750/-.
On T+3 when the Exchange sends the Auction note to the Broker, the price in the Auction note would be
“The higher of Valuation debit or the price at which the stock has been bought in the Auction market.”
In the above example, the Exchange would debit the brokerage’s account with a sum of Rs. 78,000 even though the stock was bought at a value of Rs.75, 000. The difference of Rs. 3000 (780-750)*100 would be transferred to the Investor Protection Fund.
If, in the Auction, the stock gets bought at Rs.850/- then the Exchange would debit an additional Rs.70 (Rs.850 – Rs.780 which was earlier blocked as Valuation Debit).
What happens if the Exchange finds no fresh sellers in the Auction market?
In such a case, the exchange settles it in cash on the basis of Close out Rate. Close out rate is the highest price of the stock from when you sell to the Auction day or 20%, whichever is higher.
So in the above example, the exchange would close out the trade at Rs.960 (20% higher than 800) and Mr. X, the seller of the stock who defaulted, will have to bear the auction penalty of Rs.16000 (960-800*100).
It is a tough topic to simplify, but hopefully this clarifies your queries on “Short Delivery.” Also do read the blog on BTST(Buy Today Sell Tomorrow).
