Decode the grey market premium and learn how to use it as a signal for IPO investment decisions.
Understanding GMP: The Complete Guide
The Grey Market Premium (GMP) is an unofficial indicator of how much premium investors are willing to pay for IPO shares before the official listing.
What is GMP?
GMP represents the price at which IPO shares are being traded in the grey market — before the official stock exchange listing. It's expressed as:
- Absolute GMP: ₹50 above the issue price
- GMP%: 25% above the issue price
How to Use GMP
| GMP% | Signal |
|---|---|
| >50% | Strong Buy |
| 20-50% | Very Good Buy |
| 10-20% | Good to Buy |
| 5-10% | Neutral |
| <5% | Caution |
Limitations of GMP
GMP is not always accurate. It can be:
- Manipulated by grey market operators
- Wrong in either direction
- Based on limited information
Final Takeaway
Use GMP as one data point among many. Never make IPO investment decisions based solely on GMP.
