Real IPO research doesn't start with grey market chatter, it starts with a document the company is legally required to file, disclosing exactly what it does, what it earns, and what could go wrong. This guide walks through how to actually use that document, alongside price band, subscription data, and the financial ratios that tell you whether an IPO's asking valuation is reasonable or a stretch.
How should I research an upcoming IPO in India?
Start with the company's actual filed documents, not news summaries or informal chatter. Read the DRHP or RHP directly, particularly the risk factors and financial statements. Check the price band and what valuation it implies compared to listed peers in the same industry. Look at the fresh issue versus offer for sale split, and review subscription data as it comes in, treating it as one data point, not a verdict. Every one of these is covered in detail below.
What is a DRHP? What is an RHP?
A DRHP, Draft Red Herring Prospectus, is the preliminary document a company files with SEBI when planning an IPO, containing detailed business information, financial statements, and risk disclosures, but without the final price or exact issue size, those come later. It's called "draft" because SEBI reviews it and the public can comment during a defined window before it's finalized.
An RHP, Red Herring Prospectus, is the updated version filed closer to the actual IPO launch, incorporating any changes from SEBI's review, and typically including the price band used for the actual offering. Think of the DRHP as the first, reviewable version, and the RHP as the near-final version investors actually see the offer terms in.
What should I look for in a DRHP?
The risk factors section first, companies are legally required to disclose material risks to their business, and it's often long and specific, worth actually reading rather than skipping, since it tells you directly what the company itself considers its biggest vulnerabilities. Financial statements next, revenue and profit trends over several years, not just the most recent one, and whether growth is genuinely improving or was cherry-picked from a strong recent period.
Check the objects of the issue, exactly what the company plans to do with the money raised, debt repayment, expansion, general corporate purposes, since this tells you whether the capital is funding genuine growth or just settling existing obligations. Review promoter and management background, any disclosed litigation, and related-party transactions, deals between the company and entities connected to its promoters or management, which deserve extra scrutiny for potential conflicts of interest.
Fresh issue vs offer for sale?
A fresh issue means the company itself issues new shares, raising new capital that goes directly to the company for its own use, increasing the total share count in the process. An offer for sale (OFS) means existing shareholders, promoters, early investors, or PE and VC funds, sell their existing shares to the public, with proceeds going to those selling shareholders, not to the company itself.
Many IPOs combine both. Checking the split matters, a heavily OFS-weighted issue means existing investors are largely cashing out rather than the company raising fresh growth capital, worth understanding as context, not an automatic red flag, since there are legitimate reasons for both.
What is the price band?
The price band is the range, a lower and upper price, within which investors bid for shares during a book-built IPO. The final issue price gets determined within that band based on the actual demand received across investor categories during the bidding process, rather than being fixed in advance.
How can I judge whether an IPO valuation is expensive?
Compare the valuation implied by the price band, P/E ratio, price-to-book, or EV/EBITDA depending on the industry, against genuinely comparable, already-listed peers in the same sector, not the market broadly. Check whether the company's actual disclosed growth rate and margins justify trading at a premium to those peers, or whether the valuation seems to be pricing in a story that isn't yet backed by the numbers in the DRHP or RHP.
This is the same discipline worth applying to any narrative-driven investment theme, verify the valuation against actual disclosed fundamentals, not against how exciting the company's story sounds in marketing material.
What is IPO subscription data?
Subscription data shows how many shares were applied for relative to how many were actually offered, published as the bidding window progresses, broken down by investor category, Qualified Institutional Buyers (QIB), Non-Institutional Investors (NII), and Retail Individual Investors (RII) among them. Heavy oversubscription in a specific category reflects strong demand from that group specifically.
Treat subscription data as one genuine, real data point, not a guarantee of anything. Similar to grey market premium, covered in a companion guide on this site, strong subscription numbers have not reliably predicted strong listing performance in every case, demand before listing and price behavior after listing are related but distinct things.
How is allotment decided?
For retail investors specifically, if an IPO is oversubscribed in the retail category, allotment is typically decided through a computerized lottery system, designed to distribute the limited available shares fairly among all eligible applicants, rather than allotting proportionally to everyone who applied. This is why applying for an IPO doesn't guarantee you'll actually receive shares, even if you applied correctly, oversubscription in your category means allotment comes down to that lottery process.
Institutional and non-institutional categories generally follow a more proportional allotment approach, a structural difference from how retail allotment works specifically.
What financial ratios should investors review?
P/E ratio compared against listed industry peers, revenue growth trends over multiple years, not just one, profit margins and whether they're expanding or contracting, debt-to-equity ratio, and return on equity (ROE) as a measure of how efficiently the company uses shareholder capital. None of these mean much in isolation, the comparison against genuinely similar, already-listed peers is what actually tells you whether the numbers are strong, average, or concerning for the specific industry.
Where can investors verify IPO documents?
SEBI's official website publishes DRHPs and related filings directly, and NSE and BSE both host prospectus documents for IPOs listing on their exchanges. Treat these as your primary, authoritative sources, rather than relying solely on news summaries or third-party recaps, which can simplify or omit details that matter for your own research.
What risks should I check before applying for an IPO?
Read the risk factors section in the DRHP or RHP directly, rather than assuming a company's risks are generic or boilerplate. Check the valuation against real peers, not just whether the story sounds compelling. Note whether the issue is heavily OFS-weighted, understand what the raised capital will actually fund, and review any disclosed litigation or related-party transactions that might signal governance concerns.
And treat both subscription data and grey market premium as partial, informal signals, not decision-making tools on their own, the company's actual disclosed fundamentals in its official filings remain the most reliable source you have.
Once a company actually lists, real-time price behavior and ongoing research tools apply the same way they would to any listed stock. Neostox's paper trading covers equities, futures, and options on live NSE and BSE market conditions, useful for studying how a newly listed stock actually trades once it's genuinely on the exchange, with virtual money, before committing real capital.
