Particularly, investors look at the bulk and block deals which show a keen interest in the big stocks. If several deals like that happen in stock continuously over a period of time, these can be taken as a sign of confidence and the price of the stock may increase in the near future but big institutions or investors buying the shares through such deals does not mean that the stock for this will increase in future.

These deals do not necessarily mean that the expected price may likely increase or down.

It could also happen in the operator driven counters. These bulk and block deals are considered not a good investment strategy. It is difficult to predict the conditions or the circumstances under which the buyer is buying or selling the shares. Investors are advised not to make any assumptions for the prices that will likely increase or decrease on the basis of such deals and the investors are advised to look into their fundamentals, their past performance, their future plans of the company before investing in any company. If any such trade has been made through a single transaction, the broker shall inform the BSE/ NSE on an immediate basis about the fact that the particular transaction has been conducted or made.

Main characteristics of the Bulk deal 

  1. It considers as an indication of the Concentration of interest : 

Bulk Deals are basically in the equity markets. It is important to know that the bulk deal is buying or selling since every transaction has two sides. A bulk deal gives us some important clues and is different from block deals. These are different from the block deals. 

It creates a sign of interest in the particular stock. It tends to indicate the sudden interest from the informed investors. Over the period of time, the BSE and the NSE seem to check the impact of the stock price of the bulk deal. It is obvious from the fact that the concentration of interest involved in any of the institutions has a positive impact on the prices. The reverse is in the case of consistent selling the word of caution is warranted.

Smart investor’s deals by reporting and executing slightly lower than 0.5 per cent marks. 

  1. Separation of the intraday trades and the bulk transfers: 

Firstly, we need to separate the normal trading day transactions and the bulk deal transactions. Such data are the intraday trade data and the short-term trade data. These are basically the large investors and the proprietary books trying to ride for the short-term profits. They do not indicate anything. 

Secondly, these sets of data are transacted among the institutions. We need to see that the larger positions in the bulk deals segment are nothing but the Foreign Institutional Investors, Mutual Funds, large High net worth individuals and the promoter’s actually shifting ownership around them. 

Thirdly, it shall be prudent that the bulk deals are backed by the heavy shortage of funding in future or the arbitrage funds. This is most likely an arbitrary position, not a direct indication. 

  1. Focus on the Bulk deal trends over a period of time: 

This is the most important takeaway from the bulk deal data. It took a period of 2 years to integrate the bulk data and try to sort it out on the basis of the stock and the date. It will give you

a better and clear idea of how the price of the stock has moved in conjunction with the bulk deals. 

It gives you an idea of which the traders and the investors are the most adept at catching the trends as evidenced by the future movement in the process. If these factors are combined these bulk deals become relevant and workable from the view of the selection of stock perspective. 

Bulk deals reveal only the part of the interest built up in the stock and manner times are not indicative. Aggregation of long-term bulk deals does not give you important clues. The onus on them is that a detailed study is to be done before embarking on an investment decision. We just need to be cautious there shall be hidden wisdom in the bulk deals. 


Thus, bulk and block deals are the two variants of market transactions that are pre-owned by the big institutional investors, large funds and the high-net-worth individuals to execute the large volumes in the stock market. Each of them has its own advantages and disadvantages and its differentiation. Where bulk deals are visible to everyone as their transaction is made during the regular market hours whereas block deals are transacted through a special trading window and afford a greater degree of privacy to the concerned parties. 

However, Bulk deals need to report the transactions made at the end of the day and the information shall be made available to the public. Investors shall utilize the data on bulk and block deals which creates the set indicators in their trading strategy as they create larger corporate interest in the direction of the trade. This data shall be used with caution which can often be misleading.
