DostIpo aggregates IPO information exclusively from publicly available sources, and maintains a record of where each figure originates:
| Data type | Primary source |
|---|---|
| Bidding dates, price band, lot size | Exchange filings (BSE/NSE) and the offer document |
| Live subscription ratios | Registrar and exchange disclosures, captured periodically during the bidding window |
| Reservation & anchor book | RHP disclosures and exchange allotment intimations |
| Restated financials & KPIs | The company's offer document (RHP/DRHP) |
| GMP | Grey-market dealer quotes, unofficial by definition |
| Allotment / listing outcomes | Registrar portals and exchange listing notices |
During live offer periods, automated collectors poll sources roughly every thirty minutes. Each snapshot is timestamped before it is stored, so every figure on the site can be traced to a specific moment. Between offer windows the schedule relaxes; upcoming issues are re-checked whenever new filings appear.
GMP is the price at which IPO shares change hands unofficially before listing. It is an estimate built on market chatter, not an exchange-traded price: there is no settlement guarantee, no regulator, and quotes can move within minutes. Our desk records the prevailing quote, its trend direction over successive checks, and computes the implied listing gain as GMP divided by the upper price band. We always display it with these caveats attached, never as a guaranteed listing price or promised return.
Category-wise subscription ratios (total, QIB, NII including the big/small split, retail and employee) are snapshotted periodically while bidding is open, and each snapshot is retained to build a day-wise progression for the issue. Figures are final only when the bidding window closes; intermediate values can and do change materially within hours.
Three-year restated financials (assets, income, PAT, EBITDA, net worth, reserves, borrowings), key performance indicators (ROE, RoCE, RoNW, debt/equity, PAT margin, EBITDA margin, NAV, price-to-book) and pre- versus post-IPO valuation metrics are parsed directly from the RHP's restated financial sections. If a figure is not yet confirmed from the document, it does not appear on the page.
All dates come from official filings and exchange announcements and are updated whenever new announcements land. Allotment outcomes are confirmed only on the official registrar portal. Listing prices are set by order-book demand on the exchange, never by GMP, whatever the headlines imply.
We would rather state our limits than hide them: grey-market quotes vary between dealers and cities; SME subscription data can arrive later than mainboard data; automated parsing of offer documents may lag for brand-new filings; and news-style reports are generated from the dataset, so they are only as fresh as the last collection cycle. When something is missing, the pages say so.
Scores are never rewritten when the methodology changes — a historical 32/90 stays 32/90, labelled with the version that produced it, so old and new scores stay scientifically comparable:
The X-Ray score is a deterministic, rule-based composite — no hidden model, no analyst discretion. Seven pillars, 100 points in total. Every IPO page repeats the exact formula and that IPO's computed steps under X-Ray Evidence, so any score can be re-derived by hand:
Total: a raw sum of the pillars that could be scored, never stretched to 100. A pillar with missing inputs is labelled PENDING and skipped, never scored 0 — so a 62 with two pillars pending is not worse than a 62 fully scored, just less complete.
Worked example: GMP ₹36 on upper band ₹146 is a 24.7% premium, about four-tenths of the 60% full-marks bar, giving 4 out of 10 on sentiment.
Two products, two GMP weights: the Fundamental X-Ray above carries grey-market sentiment at only 10 out of 100, so no unofficial quote can drive the score. Short-term heat is a separate product, Listing Momentum (subscription velocity, GMP velocity, end-of-day acceleration), where the grey market naturally carries about a third of the weight. Read them together: strong fundamentals with cooling momentum means patience; weak fundamentals with hot momentum means caution.
Signal from score: 70% or more of the scorable points reads POSITIVE, 60%+ MIXED, 45%+ NEUTRAL, below that WEAK — and anything scored on under 60 points stays NEUTRAL marked DATA PENDING, however high it looks.
Honesty rules: valuation can never be a perfect 20 out of 20 by design — perfection cannot be claimed before listing. The engine source (bot/scores.py) is the authority: if this page ever disagrees with it, the code wins and the page is a bug.
Every live IPO passes automatic consistency checks around the clock. The system is fully automated and says so openly: passing earns Auto-verified — a consistency certificate, not a truth certificate. A bot can check that figures agree with each other, never that they are true:
Auto-fix whitelist is deliberately tiny: only legacy money-unit strings whose raw unit is itself the evidence (for example, an old 1800.00 million stored as rupees-crore becomes Rs180 Cr, with the before/after written to a public audit trail). Anything ambiguous — two sources disagreeing, an unclear RHP figure, a suspicious quote — pages the founder on Telegram instead of guessing.
