Bulk Deal
A bulk deal is a transaction where a single client's total buying or selling in one stock crosses 0.5% of the company's listed equity shares within a trading day; exchanges disclose these deals — with the client's name, quantity and price — the same evening.
Bulk deals happen in the normal market during regular trading hours; what makes them special is only the mandatory disclosure. Because the counterparties are named, the daily bulk-deal list is one of the few windows into what large, identifiable investors — funds, promoters' vehicles, well-known individual investors — are actually doing.
Reading the list needs care. A famous investor appearing as a buyer can spark follow-on buying, but many bulk deals are mechanical: fund rebalancing, inter-scheme transfers between a fund house's own schemes, or one leg of a pre-arranged transaction. The price at which the deal happened, relative to the market price, often hints at how motivated the buyer or seller was.
Bulk deals differ from block deals: a bulk deal is defined by size crossing the 0.5% threshold in the normal market, while a block deal is a separate, pre-negotiated trade executed in a dedicated exchange window.
In practice

Common questions
Where can I see today's bulk deals in India?
NSE and BSE each publish a bulk-deal list after the market closes every trading day, naming the client, whether it bought or sold, the quantity and the weighted average price. Each exchange lists only the trades executed on its own platform, so one investor's activity in a stock can be split across the two lists.
Who has to report a bulk deal?
The broker that executed the trades reports them to the exchange on the same day, and the exchange publishes the details. The client files nothing for the bulk deal itself. If the trades take its holding across a takeover-code threshold such as 5%, it must also make a separate SAST disclosure to the company and the exchanges.
Does a bulk deal tell you who the real buyer is?
Only partly. The list names the client account the trades went through, which may be a fund, a company, an individual or a foreign portfolio investor's registered entity rather than the ultimate owner. Foreign funds often trade under names that differ from the brand people know, and the list never states why anyone bought or sold.
How stocks tend to react
Stocks often move when a respected investor's name appears on the buy side of a bulk deal, and can fall when a large holder is seen exiting. The signal is stronger in smaller companies, where a 0.5% stake change is harder to absorb.
