  2. Name of the Client
  3. Quantity of Shares bought/sold

What is Block Deal?

A trade of more than 5 Lakh shares or of a value of more than Rs. 5 Crores of a company is called as a Block Deal.

Block Deal trades can only be conducted in a special trading window which is opened from 9:15 AM to 9:50 AM. The price at which such trades can be conducted is in the range of +1% to -1% of the current market price/ previous day’s closing price as applicable.

It is the responsibility of the broker conducting such a trade to immediately inform the stock exchange i.e. BSE/NSE (as the case may be) about the fact that such a transaction has been conducted on the exchange. The following details regarding the Block Deal are required to be intimated by the broker to the stock exchange:-

  1. Name of the Scrip
  2. Name of the Buyer/Seller
  3. Quantity of Shares bought/sold
  4. Traded price

After the receipt of such information regarding the Block Deal, the exchange shall make such information public on the same day on which the trade has been conducted. Such block deal trades must always result in delivery and cannot be squared off during the day. STT is also charged on such orders in the same manner as charged on all other orders.

Matching of orders in a Block Deal

Block deals are always conducted in a special trading window which is opened for a period of 35 minutes before the start of the normal trading hours. Moreover, the no. of buyers/sellers is also very limited as there are very few investors who buy/sell such high value/volume of shares.

For a block deal to get traded, the quantity and the rate should be exactly the same as the opposite side block order deal. Block deal orders will be matched against the counter order with the same quantity and rate on a time priority basis.

A Block deal cannot be partially traded and if not traded fully the order will get cancelled. The block deal order remains in the system only for a period of 90 seconds after which it automatically gets cancelled if it remains unexecuted.

Example 1

  1. Client ABC enters buy block deal order of 7 Lakh shares @ Rs. 80
  2. Client XYZ enters sell block deal order of 7 Lakh shares @ Rs. 80

In the above case, the buy block deal order will get matched with the sell block deal order as the quantity and the rate of both the orders is the same.

Example 2

  1. Client ABC enters buy block deal order of 20 Lakh shares @ Rs. 100
  2. Client XYZ enters sell block deal order of 10 Lakh shares @ Rs. 100
  3. Client PQR enters sell block deal order of 10 Lakh shares @ Rs. 100

In the above mentioned case, the buy block deal order will not match with any of the sell block deal orders as the quantities do not match although the rate is the same. For the block deal order to get executed both the price and the quantity to be traded shall be exactly the same.

Reason for Introduction of Bulk Deals/ Block Deals

The reason for introduction of Bulk Deals and Block Deals by SEBI is to increase greater transparency in bulk/block deals and to prevent rumours and speculation. When the trading volumes in a stock increase, it creates all sorts of rumours including a potential sale by the promoter or an increased interested from the institutional investors.

Before these guidelines for disclosure of Bulk deals and Block deals was issued, such transactions were completed in secrecy. Apart from the parties involved i.e. the buyer and the seller, no information on block deals was available to retail investors and rumours about the size of the deal used to drive up the stock price on  subsequent days.

The introduction of the Bulk Deals and Block Deals is therefore considered very good as it gives greater transparency and is basically meant to clarify and explain the reason for the increase in volumes.

Interpretation of such Bulk Deals and Block Deals

Such Block Deals and Bulk deals are usually done by FII’s, DII’s, Mutual Funds and in some cases by very high net worth individuals as well. Such block deals may not necessarily mean that the price is expected to go up or down.

However, in case of bulk deals happening on a continuous basis in a share, it could be a sign of big variance expected in the share price in the near future. Yet this could also happen in operator driven counters.

Blindly following the block deals and bulk deals information is not a good investment strategy. It is very difficult to predict the circumstances under which the buyer is buying/selling such shares.

 Investors are advised not to blindly assume that the price will increase or decrease on the basis of such deals and investors are advised to look into the fundamentals of the company, its past performance, future plans etc before investing in any company.
