Bulk Deals

A bulk deal is a single trade transaction on NSE or BSE in which the total quantity of shares traded exceeds 0.5% of the total number of equity shares listed on the exchange for that security — executed between a buyer and seller during regular market hours in a single transaction or series of trades on the same day. SEBI mandates that bulk deals be reported to the stock exchange on the same trading day, and exchanges must publish this information publicly within one hour of the market close. Bulk deal disclosures reveal significant buying or selling activity by institutional investors, promoters, foreign portfolio investors, and mutual funds — providing retail investors with insights into large-scale institutional position changes. Bulk deals are different from block deals — which are executed in a separate, pre-market window (8:45 AM to 9:00 AM) specifically designed for large trades exceeding ₹10 crore between two pre-identified counterparties, minimising the market impact of large institutional trades. For Indian equity investors, bulk deal data published daily on NSE and BSE is a valuable secondary research signal — significant bulk buying by reputed institutional investors often precedes positive price momentum, while large promoter bulk sales (particularly at discounted prices) can signal near-term selling pressure or promoter liquidity needs.
