IPO GMP Calculator — Frequently Asked Questions

What is IPO GMP?

GMP (Grey Market Premium) is the unofficial price at which IPO shares are traded before the official listing on NSE or BSE. A positive GMP means demand is high in the grey market; a negative GMP means investors expect a discount listing.

How accurate is the IPO GMP calculator as a listing predictor?

GMP is most reliable within 24–48 hours of listing when the IPO is heavily subscribed and market conditions are stable. It is an unofficial signal only — always cross-check with official subscription and allotment data on NSE India or BSE India.

What does negative GMP mean?

A negative GMP means IPO shares are trading below the issue price in the grey market, strongly suggesting a discount listing. The larger the negative GMP, the worse the expected listing. For example, Striders Impex had a GMP of −₹2.16 and listed at ₹69.84 against an issue price of ₹72 (−3%).

Is grey market trading legal in India?

The grey market is unofficial and not regulated by SEBI. There is no legal protection if the counterparty defaults. Always rely on official NSE/BSE data for investment decisions.

What is a good GMP percentage for listing gains?

Generally: GMP above 10% of issue price is very strong; 4–10% is good; 1–4% is weak positive; negative GMP signals a discount listing. Always combine GMP with subscription data (QIB, NII, retail) and overall market conditions for a complete picture.
