Important Notes About Grey Market Premium

Grey Market Premium (GMP) is an unofficial value that indicates investor sentiment before the IPO listing. It is the premium amount at which IPO shares are traded in the grey market before they are officially listed on the stock exchange.

GMP fluctuates based on market conditions and investor sentiment. A positive GMP suggests the market expects the stock to list above its issue price, while a negative GMP suggests it may list below the issue price.

The actual listing price may differ from the estimated price based on GMP due to market conditions on the listing day. GMP is not an official indicator and should not be the sole basis for investment decisions.

IPOwiz updates the GMP values regularly, but these values are sourced from unofficial channels and should be used as a reference only.
