NSE Bulk Deals — transactions where total traded quantity exceeds 0.5% of the number of equity shares listed on the exchange. A key indicator of significant institutional buying or selling activity.

A bulk deal is a large trade in which a single client buys or sells at least a prescribed percentage of a company's listed equity shares within one trading day, often defined around 0.5–1% thresholds. Bulk deals occur in the normal market session and are reported by exchanges because such large transactions can influence price, liquidity and investor sentiment in the underlying stock. Bulk‑deal bhavcopy data consolidates daily disclosures of symbol, client, buy/sell side, quantity and price, allowing traders and analysts to study institutional accumulation or distribution and to integrate historical bulk‑deal data with standard equity bhavcopy data.
