In depth
Unlike a block deal, a bulk deal happens in the ordinary market through the normal order book, and is identified after the fact by its size relative to the listed shares. Brokers must report it to the exchange, which publishes the client name, quantity and average price the same day. That disclosure is what makes bulk deal data a window into institutional and high-net-worth activity. Reading a single bulk deal as a recommendation is a mistake: the buyer's reasons, horizon and hedges are all invisible, and the price at which they bought has already passed.
Worked example
A company has 20 crore shares listed, so the bulk deal threshold is 0.5% x 20 crore = 10 lakh shares. A client buying 12 lakh shares in a day crosses it, and the exchange publishes the name, quantity and average price after the close.
