• Undersubscribed (not enough registered) refers to the issue of securities, the demand for which does not match the available supply.

  • An IPO with insufficient subscriptions is usually a negative signal, as it indicates that people are not eager to invest in the company’s shares or that they are not selling well.
  • Underbooking can also occur if the issuer sets the placement price too high.
  • Institutional or accredited investors are most often eligible to subscribe to a new issue.
