Understanding Block Deals and Bulk Deals in the Stock Market
The stock market is a dynamic arena where various participants, from retail investors to large institutions, engage in the buying and selling of shares. Among these participants are institutional investors, such as investment banks, hedge funds, mutual funds, pension funds, foreign institutional investors (FIIs), high-net-worth individuals (HNIs), and company promoters, who have access to more substantial capital and insider knowledge compared to retail investors. This disparity in resources and information leads to different trading patterns, with institutional investors often executing large transactions through block deals and bulk deals. While the names may sound similar, these two types of transactions differ significantly in terms of execution, visibility, and impact on the market.
What is a Block Deal?
A block deal is a large-scale transaction in which shares exceeding 500,000 in number or worth more than ₹10 crores are bought or sold. The minimum value of block deals was originally set at ₹5 crores but was raised by the Securities and Exchange Board of India (SEBI) to ₹10 crores in 2017. These deals are executed during a special trading window known as the “block deal window.” Unlike regular trades, block deals do not appear on the volume charts visible to retail investors.
Some of the key features of block deals are:
- Special Trading Window: Block deals are executed only during a specific time frame, called the block deal window. This window operates in two shifts:
- Morning Shift: 8:45 AM to 9:00 AM
- Afternoon Shift: 2:05 PM to 2:20 PM
- Block Reference Price: Block deals are conducted based on a Block Reference Price, which is the price used to place orders. The reference price for the morning shift is the previous day’s closing price, while for the afternoon shift, it is the volume-weighted average price from 1:45 PM to 2:00 PM.
- Unmatched Orders: If a block deal order isn’t matched in the morning shift, it is canceled and won’t carry over into the afternoon shift.
What is a Bulk Deal?
A bulk deal is defined as a transaction involving at least 0.5% of a company’s total listed shares. Unlike block deals, bulk deals occur during normal trading hours and are visible to all market participants. They are reflected in the volume charts and can influence stock prices in real-time.
Some important characteristics of bulk deals include:
- Trading Hours: Bulk deals happen during regular trading hours and are visible to all investors.
- Volume and Reporting: Bulk deals must be reported to the exchanges, including the transaction amount and the identity of the participants. The details are made available to the public at the end of the trading day.
- Option to Use Block Deal Window: If a bulk deal meets the criteria for a block deal (i.e., exceeds ₹10 crores or 0.5% of a company’s total listed shares), the parties involved have the option to execute the transaction in the block deal window or during regular hours.

How Do Bulk and Block Deals Impact Stock Prices?
While bulk and block deals can indicate significant interest in a stock, it’s essential for investors to assess these transactions carefully. Just because a bulk or block deal is executed doesn’t necessarily mean the stock will move in the direction of that trade. However, repeated transactions, especially in one direction (buy or sell), can indicate strong institutional interest in the stock, which may eventually influence its price.
Conclusion
Block deals and bulk deals are both used by institutional investors, HNIs, and large funds to transact substantial volumes of shares. While bulk deals happen during regular market hours and are visible to all participants, block deals take place in a designated trading window and offer a greater degree of privacy for the parties involved. Both types of deals play a role in shaping market sentiment and can provide valuable insight for investors when incorporated into their trading strategy. However, investors should exercise caution and cross-reference this data with other market indicators, as bulk and block deals alone are not always reliable predictors of market direction.
