How is GMP Calculated?
Understanding the method behind Grey Market Premium calculation.
GMP Calculation Formula
GMP = Grey Market Price - Issue Price
The GMP is simply the difference between the market price at which shares are trading in the grey market and the official issue price set by the company.
Example
If an IPO has an issue price of Rs 100 and the grey market is trading it at Rs 125:
GMP = 125 - 100 = Rs 25
This means market expects a listing gain of Rs 25 per share (25% gain).
What Influences GMP?
- Subscription Ratio: Higher subscription = higher GMP
- Company Quality: Strong fundamentals attract premium
- Market Conditions: Bull market = higher GMP
- Industry Trends: Trending sectors command premium
- Demand vs Supply: More demand = higher GMP
- Valuation: Cheaper valuations get higher GMP
