A sudden spike in trading volume can change the mood of the market within minutes. Investors start checking charts, headlines, and disclosures, trying to understand what just happened. While there can be various reasons for such instances to happen, most of the time, it is a result of bulk and block deals

While many traders think that these two are the same when it comes to stock market trading, this is not true. Knowing the real difference between bulk deals vs block deals helps you read market moves with clarity.

So, if you are a trader looking to find the answer, then read this guide. Know their meaning and the block deals vs bulk deals as well. 

What Is a Block Deal

A block deal is a large single trade. It is carried out between a buyer and a seller at a pre-decided price. It is executed through a separate trading window. This is mainly to limit sudden price movement in the regular market.

Features of a Block Deal

  • Minimum transaction value is Rs. 10 crore.

  • Executed in a special block deal window.

  • Price and quantity are fixed in advance.

  • Mostly used by institutional investors.

  • Trade details are shared by the stock exchange on the same day.

What Is a Bulk Deal

A bulk deal is another important form of trade in the stock market. It happens when a large number of shares are bought or sold in the open market. This is done during normal trading hours. These trades are done as normal trades in the market. Just the volume is high; the rest remains the same.

Features of a Bulk Deal

  • Involves trading of more than 0.5% of a company’s equity in a single day.

  • Takes place during normal market hours.

  • Executed at prevailing market prices.

  • Can be completed through one or multiple trades.

  • Bulk deal information is disclosed after market hours.
