What is IPO GMP and should you trust it?
GMP (Grey Market Premium) is the informal price at which IPO shares trade before the stock officially lists on NSE or BSE. It reflects demand in an unregulated grey market, and is not a legally binding price.
GMP reliability varies. For large mainboard IPOs with 5x+ QIB subscription, GMP is a reasonable directional indicator. For SME IPOs or those with low QIB subscription, GMP can be gamed by grey market operators. stoicHQ rates reliability based on IPO size, QIB interest, and promoter credibility.
✓ Use GMP to gauge sentiment
High GMP + high QIB subscription = institutional demand real
✗ Don't apply if subscription is low
Low QIB + high GMP = grey market manipulation risk
✓ Track trend, not just today's number
Rising GMP into close date is a positive sign
✗ Never apply only based on GMP
Allotment odds, valuation, and use of proceeds matter more
