Difference Block Deals and Bulk Deals

  • Mar 4, 2025

Institutional investors manage vast amounts of wealth and often have privileged information about the firms they invest in, which sets them apart from retail investors. They frequently engage in substantial trading volumes and execute block or bulk deals. This article will cover the distinctions between bulk deals vs block deals.

Understanding of The Block Deal

In order to understand the differences between bulk deals and block deals, it is important to clarify their meanings. Let us start by explaining what block deals are.

A block deal is a single transaction that involves the exchange of shares worth more than Rs. 5,00,000 or, in cases where the total traded value exceeds Rs. 10 crores.

It's worth noting that SEBI modified the criterion for defining the value of the block deal from a fixed amount in crores to the current Rs 10 crores. In today's stock market landscape, block deals occur within a designated trading window known as the "block deal window."

Importantly, due to the special nature of these transactions, block deals are not accessible to retail investors and are not displayed on the value charts of any trading platform.

While you might draw a similarity between subscribing to an upcoming IPO and a block deal, it's crucial to recognise substantial differences in the quantity and value of shares involved.

Block trades executed within 35 minutes after trading opens must be immediately reported to the exchange by the broker and cannot be squared off intraday.

What Is the Concept of Bulk Deal?

In the stock market, a Bulk Deal is a transaction in which a single entity, such as an institutional investor or a prominent trader, buys or sells a huge amount of a company's shares in a single trade. The definition of a bulk deal varies depending on the stock exchange and regulatory authority. Still, it often entails a transaction in which the number of shares exchanged exceeds a proportion of the company's total outstanding shares.

As per the bulk deal meaning, the transactions are generally disclosed to the stock exchange where the trade happens and made available to the public after the trading day. Market participants actively follow these transactions because they can give insights into the trading behaviour of institutional investors and other significant market participants, which can affect a stock's price and the broader market mood.

A Comparative Analysis Between Block Deal vs Bulk Deal

Here are the differences between Bulk Deal vs Block Deal:

  • Definition: Bulk Deals are large purchases or sales of a company's stock exceeding a predefined threshold. Block Deals are substantial sales or purchases of shares in a single transaction exceeding 5 lakh shares or a total value exceeding Rs. 5 crore.
  • Transaction Size: It is Smaller compared to Block Deals and Larger compared to Bulk Deals.
  • Impact on the market: Few shares involved have a limited impact on price. Whereas many shares involved have a bigger impact, price fluctuations are possible.
  • Reporting Requirements: Bulk Deal and Block Deal have different time frames for reporting to the stock exchange.
  • Disclosure: The names of buyers and sellers are made public immediately after the transaction has been completed.
  • Purpose: Portfolio management purpose or trading purpose, often used by retail and institutional investors. Generally, mutual funds use it to acquire or dispose of a significant stake in a company in bulk deal and block deal.
  • Regulation: Companies are subject to more stringent regulations and reporting requirements as stock exchanges and market regulators monitor them.
  • Market Reaction: Bulk deals are less likely to attract immediate attention from traders and the market, while block deals are more likely to draw attention from participants, resulting in increased trading activity and volatility.

How Does Block or Bulk Deal in A Stock Affect It?

Block and bulk deals refer to the purchase or sale of a large number of shares or securities in the stock market. If bulk deals are repeatedly made in the same direction, it may indicate a growing interest in the stock, aligning with the direction of the bulk trade.

These transactions can have a significant impact on investors. However, it is crucial to approach these signals with caution and not rely solely on them. It is important to consider other indicators and trends before making any trading decision.

Conclusion

Bulk trades and block trades are two different types of transactions in the stock market. NSE bulk trades have an impact on the real-time pricing of stocks and also provide market insights. On the other hand, block deals are pre-arranged trades that are executed off-market in order to minimise the immediate impact on the market. Having a clear understanding of these differences between bulk and block deal can help traders and investors make informed decisions and enhance their proficiency in stock trading.
