Difficult Terms Explained:

  • IPO (Initial Public Offering): This is the process through which a privately held company offers its shares to the public for the first time. It's a way for companies to raise capital from investors.
  • GMP (Grey Market Premium): This refers to the premium at which an IPO's shares are traded in the unofficial 'grey market' before they are officially listed on the stock exchange. It's often used as an indicator of investor demand and potential listing gains.
  • Allotment Status: This refers to the official record that indicates which applicants have been allocated shares in an IPO and how many shares they have received.
  • Demat Account: A Dematerialized Account, or Demat Account, is an electronic account used to hold shares and other securities like bonds and mutual funds.
  • Offer-for-Sale (OFS): In an Offer-for-Sale (OFS), existing shareholders of a company sell their shares to the public during an IPO. Unlike a typical IPO, the company itself does not issue new shares and therefore does not raise any new capital. The money from the sale goes directly to the selling shareholders.
  • Subscription: In the context of an IPO, subscription refers to the process where investors place orders to buy shares. When an IPO is oversubscribed, it means more investors want to buy shares than are available.
