IPO Grey Market Premium Explained
IPO GMP or IPO Grey Market Premium is the value which indicates the listing gain for a particular IPO. If the IPO of XYZ company is having the issue price of Rs 100 and it is expected to list at the exchanges at Rs 120, then the IPO GMP or IPO Grey Market Premium is of Rs 20.
The IPO GMP moves daily up and down and it might be different from different sources. There is no exact IPO GMP, but many big heads try to make calculations as per the demand of the IPO and the market scenario.
IPO GMP Trend (Day-wise Movement)
Tracking the IPO GMP trend tells you more than the current premium alone. A rising GMP trend indicates growing investor confidence and high demand, often signalling a strong listing. Conversely, a falling trend might suggest waning interest or negative market sentiment.
We track the day-wise movement of GMP for every IPO. You can view the complete GMP history and trends by clicking on any specific IPO details page from the list above.
IPO Kostak Price & Subject to Sauda Rates
What is IPO Kostak Price?
IPO Kostak Price (Application Price) is the amount an investor receives by selling their IPO application, regardless of allotment status. It allows booking fixed profits safely in the Grey Market.
What is Subject to Sauda?
Subject To Sauda Price is the profit amount an investor gets by selling their application *only if* they get the allotment. If no allotment is received, the deal is void (no profit, no loss).
Is IPO GMP Reliable for Listing Gains?
- • Indicator Only: The IPO Grey Market Premium is just an unofficial indicator of market sentiment and demand. It is not regulated by SEBI or any stock exchange.
- • Daily Volatility: GMP changes every day, hour, or even minute. A high GMP today does not guarantee a high listing price on the listing day.
- • No Transaction Service: We do not buy, sell, or facilitate any grey market transactions. We only provide information based on market resources.
- • Consult Advisors: Never rely solely on GMP for investment decisions. Always analyze the company's financials and consult your financial advisor.
What Factors are Influencing IPO GMP?
- Market Sentiment: A bullish market environment generally leads to higher GMPs as investor confidence is high. Conversely, bearish markets can dampen premiums.
- Company Financials: Strong fundamentals, consistent revenue growth, and healthy profit margins attract higher demand in the grey market.
- Subscription Figures: High oversubscription numbers, especially in the QIB and NII categories, often boost the GMP significantly.
- Peer Valuation: If the IPO is priced attractively lower than its listed peers (leaving money on the table), the GMP tends to be higher.
- Demand & Supply: The basic economic principle applies—high demand for the shares coupled with limited supply drives up the premium.
Grey Market Trading Pros and Cons
Pros
- Early Price Discovery: It gives investors an early idea of the potential listing price and market demand.
- Hedging Opportunity: Investors can lock in profits by selling their applications at Kostak or Subject to Sauda rates, hedging against listing day volatility.
- Liquidity: It provides an avenue for liquidity before the stock is officially listed on the exchange.
Cons
- Unregulated & Risky: The grey market is unofficial and unregulated by SEBI. Deals are based on trust, carrying high counterparty risk.
- No Legal Recourse: Since it's unofficial, you cannot file complaints with authorities if a trade is not honored.
- High Volatility: Premiums can crash overnight due to negative news or global market sell-offs.
Real-Life Example of IPO GMP
Let's look at the blockbuster IRCTC IPO from 2019 to see how GMP predicted listing gains:
Scenario:
- IPO Name: IRCTC
- Issue Price: ₹320 per share
- Lot Size: 40 shares
- GMP (Before Listing): ~₹320+ per share
Actual Listing:
The stock listed at ₹644, delivering a gain of 101%.
Profit Calculation (Per Lot):
Listing Gain × Lot Size = (₹644 - ₹320) × 40 = ₹12,960 Profit
*This example shows how a strong GMP correctly indicated that investors would double their money on listing day.
