Bulk Deals – Cumulative tells us the cumulative number of shares traded under bulk deals over a given time period as a % of total shares outstanding. We’ve added Bulk Trades – 1M, 3M, 6M cumulative as screener filters. For example, Bulk Deals – 3M Cumulative is calculated by summing up the number of shares traded in all the Bulk deals that have occurred in the past 3 months, then dividing it by the total number of shares outstanding and finally multiplying it by 100 to arrive at a percentage value.

A bulk deal is a deal where the total quantity of shares bought or sold is greater than 0.5% of the share capital of the company. A bulk deal is transacted through the normal trading window and SEBI mandates the broker to report these high-value transactions. This can be looked at as a signal of building interest in a particular stock. Normally, bulk deals tend to be indicative of a sudden spurt in interest from informed investors. These basically give an indication of what stocks, big institutions, and asset management firms are buying.
