IPO GMP Consensus & Analytics Methodology
InvestorPizza provides deterministic, source-backed primary market intelligence. We do not publish speculative hearsay or unverified single-dealer whispers. Every Grey Market Premium (GMP) consensus metric, funding break-even calculation, and financial ratio is subject to strict mathematical models and cryptographic provenance.
1. Multi-Desk OTC Consensus Median Math
In informal Over-The-Counter (OTC) forward contracts, single-broker quotes are frequently subject to quote-stuffing, artificial widening of bid-ask spreads, and regional liquidity disparity. Simple arithmetic averages (μ) are highly vulnerable to extreme single-dealer manipulation.
Mathematical Consensus Formula
InvestorPizza aggregates observed quotes from multiple verified dealer desks across primary OTC geographic centers (Ahmedabad, Mumbai, Rajkot, and Jaipur). Let Q = [q₁, q₂, ..., qₙ] be the vector of observed raw premiums. We apply median aggregation:
The median metric ensures that 50% of verified dealer quotes lie at or above the reported figure, and 50% lie at or below, providing a robust, non-parametric indicator of equilibrium sentiment.
2. Outlier Truncation Algorithm (N ≥ 4)
To neutralize pump-and-dump misinformation in illiquid or high-sentiment issues, InvestorPizza enforces an automated truncation rule whenever four or more independent quotes are captured:
- Sort quotes ascending: q₁ ≤ q₂ ≤ ... ≤ qₙ
- Systematically prune the minimum (q₁) and maximum (qₙ) outliers.
- Compute the median strictly from the bounded core subset: [q₂, ..., qₙ₋₁].
- Eliminates anomalous bids intended to artificially spike or suppress sentiment.
- No truncation is performed to avoid artificial compression of limited data.
- Calculates unweighted raw median across the 1 to 3 observed quotes.
- The UI renders an explicit Low Sample Size badge.
- Explicitly warns readers that thin trading volume impairs price discovery.
3. Authoritative Provenance & Verification Protocol
All numeric parameters on InvestorPizza are governed by the four platform principles established under the Project Constitution:
Principle IAuthoritative Provenance Over Speculation
Every balance sheet metric (Revenue, EBITDA, PAT, RoNW, EPS, Net Debt) links directly to statutory Red Herring Prospectus (RHP) PDF source URLs and documented page references. No secondary aggregator estimates are accepted.
Principle IIMissing Information ≠ “Zero” or “No”
If an issuer or broker does not disclose a statutory figure, it is rendered explicitly as ? Not Documented with an explanatory provenance note, rather than substituted with zero.
Principle IIIDeterministic Calculation Chains
HNI funding break-even math, NBFC interest carry calculations, retail expected value formulas, and lot commitment limits are computed purely with client-side deterministic functions without arbitrary multipliers.
Principle IVDeterministic Rankings (Zero Commercial Bias)
Affiliate links to SEBI-registered brokers are strictly cordoned into designated affiliate cards. Commercial relationships have zero bearing on GMP consensus figures, financial ratios, or broker comparison tables.
4. Statutory SEBI & OTC Compliance Disclaimers
Zero OTC Facilitation: InvestorPizza does NOT trade, broker, execute, clear, or solicit Grey Market transactions, Kostak contracts, Subject to Sauda agreements, or any unregulated OTC contracts. We do not maintain any commercial or referral ties with grey market operators or brokers.
Unregulated & Non-Binding Status: Grey Market Premium (GMP) is an informal, unofficial metric tracked strictly for journalistic and market sentiment observation. It is not recognized by the Securities and Exchange Board of India (SEBI), the National Stock Exchange of India (NSE), the BSE Limited, or any recognized clearing corporation.
No Guarantee of Listing Returns: Grey Market premiums are volatile and subject to drastic reversal prior to listing day. A positive GMP does not guarantee listing gains, and a negative GMP does not guarantee a discount. Realized listing prices are determined solely through the official exchange pre-open price discovery call auction.
Regulatory Investment Warning: InvestorPizza is not a SEBI-registered Investment Adviser or Research Analyst.

Equity investments, particularly in initial public offerings and SME issues, carry a high risk of capital loss.
