Terms in this story

  • IPO: An IPO, or initial public offering, is the first time a company sells its shares to the general public and gets listed on a stock exchange. In India the process is supervised by SEBI and ends with the shares trading on the NSE and BSE.
  • Price band: The red herring prospectus (RHP) is the near-final IPO document that carries the price band and the opening and closing dates. From the day the band is announced, a main board IPO runs for three working days of bidding and lists a few days later.
