The range within which a stock or IPO can be priced or traded on a given day, set by exchanges or issuers to limit extreme price movements.
Price band has two important meanings in Indian markets. In secondary market trading, it refers to the daily circuit limits set by stock exchanges — the maximum percentage a stock's price can move up or down from the previous closing price. In the IPO context, it is the range within which investors bid for shares during a book-built offering.
For secondary market trading, NSE and BSE impose circuit limits of 2%, 5%, 10%, or 20% depending on the stock. When a stock hits its upper circuit, no further buy orders can be executed above that price; at the lower circuit, no sell orders below. Stocks in the F&O segment (like Reliance, TCS, Infosys) do not have daily circuit limits but are subject to index-level circuit breakers — the market-wide circuit breaker halts all trading if the Nifty 50 or Sensex falls 10%, 15%, or 20%.
In the IPO context, the price band is the range set by the issuing company and its investment bankers. For example, an IPO might set a price band of INR 350-370. Retail investors bid within this range, and the final issue price is determined through the book-building process. SEBI mandates that the price band should not exceed 20% of the floor price.
Circuit limits serve as a crucial market stability mechanism. Without them, panic selling could cause stocks to fall to near-zero in a single session, as happened in several global markets before circuit breakers were introduced. India's circuit breaker system was strengthened after the Harshad Mehta scam of 1992 and the Ketan Parekh episode of 2001.
Understanding price bands helps traders plan their orders. A stock repeatedly hitting upper circuits signals strong demand but also means you may struggle to buy at market price. Conversely, lower circuit hits indicate severe selling pressure and potential illiquidity for exit.
