What is IPO GMP (Grey Market Premium)?
IPO GMP, or Grey Market Premium, is the unofficial premium at which IPO shares trade in the informal grey market before their official listing on NSE or BSE. The grey market is not regulated by SEBI.
A positive GMP(e.g. Rs 80 premium on a Rs 400 issue) indicates the grey market expects shares to list at Rs 480 — a 20% listing gain. A negative or zero GMP suggests weak demand and potential listing below issue price.
How to Calculate Estimated Listing Price from GMP
Estimated Listing Price = Issue Price (Cap) + GMP
Example: Price band Rs 300-320, GMP = Rs 50 → Estimated listing = Rs 370 (15.6% gain)
The GMP percentage is calculated as: (GMP / Cap Price) x 100
