What is Grey Market Premium?
Grey Market Premium (GMP) is the premium at which IPO shares trade in the unofficial "grey market" before they officially list on stock exchanges. It represents the price investors are willing to pay above the IPO issue price to buy shares before listing.
How Does the Grey Market Work?
The grey market is an unofficial, over-the-counter market where IPO shares are traded before listing. Here's how it operates:
Participants
- Sellers: IPO applicants who want to lock in profits before listing
- Buyers: Investors who missed the IPO or want guaranteed shares
- Dealers: Intermediaries who facilitate grey market trades
Trading Mechanism
- Dealers quote buy/sell prices for IPO shares
- Sellers agree to deliver shares post-allotment
- Buyers agree to pay premium above issue price
- Settlement happens after listing
Types of Grey Market Trades
1. Subject to Sauda (GMP)
Trading shares at a premium over issue price:
- Both parties agree on premium amount
- Seller delivers shares after allotment
- Buyer pays issue price + premium
- Settlement depends on actual allotment
Example: IPO price ₹100, GMP ₹20. Buyer pays ₹120 per share.
2. Kostak Rate
Fixed premium for entire application, regardless of allotment:
- Seller gets fixed amount irrespective of allotment
- Buyer takes risk of no allotment
- Popular in highly oversubscribed IPOs
Example: Kostak rate ₹1,000 for retail application. Seller gets ₹1,000 whether allotted or not.

How to Use GMP Data
As One Input, Not The Only Input
- GMP reflects market sentiment, not fundamentals
- Should supplement, not replace, fundamental analysis
- Consider alongside subscription data and company quality
Tracking GMP Trends
- Monitor GMP throughout IPO period
- Rising GMP = increasing demand
- Falling GMP = declining sentiment
- Sudden changes may signal new information
GMP vs Actual Listing
GMP is not always accurate:
- Market conditions on listing day matter
- Manipulation is possible in grey market
- Sentiment can change quickly
Risks of Grey Market Trading
Legal Status
- Grey market is not regulated by SEBI
- Trades are technically informal agreements
- No legal recourse if counterparty defaults
Counterparty Risk
- Seller may not deliver shares
- Buyer may refuse to pay
- Dealer may disappear
Price Risk
- GMP can change rapidly
- What you lock in may not match listing price
- Losses are possible even with positive GMP
Calculating Expected Listing Price
Simple formula:
Expected Listing Price = Issue Price + GMP
Example:
- Issue Price: ₹500
- GMP: ₹50
- Expected Listing: ₹550
- Expected Gain: 10%

Should You Participate in Grey Market?
Reasons to Avoid

- Counterparty risk exists
- No legal protection
- Can result in losses
When Some Consider It
- To lock in guaranteed profits
- When highly confident about allotment loss
- As a hedging mechanism
Conclusion
Grey Market Premium is a useful indicator of market sentiment for IPOs, but it should not be the sole factor in investment decisions. Use GMP data alongside fundamental analysis and subscription trends. Remember that grey market trading itself carries risks, and the premium can be volatile. For most retail investors, applying through official channels and making decisions based on company fundamentals is the safer approach.
