IPO — Initial Public Offering

An IPO (Initial Public Offering) is the first time a company sells its shares to the public, after which the stock lists and trades on the NSE and/or BSE.

Most Indian IPOs are book-built: the company (and any selling shareholders) set a price band, investors bid within it over the issue days, and the final price is discovered from demand. Allocation is split into quotas — qualified institutional buyers, non-institutional (HNI) investors and retail — with anchor investors (large institutions) allotted shares a day before the issue opens to signal quality.

An IPO can raise fresh capital (new shares, money to the company), be an offer for sale by existing holders (money to the sellers), or combine both — the prospectus's 'objects of the issue' section tells you which, and it matters: fresh-issue money funds the business, OFS money does not.

After listing, the company enters the disclosure regime that MarketPing tracks — every results filing, board meeting and material event under LODR Regulation 30 — and FPI subscriptions to IPOs are exactly the 'primary route' flows that can make headline FPI numbers look positive even on weak market days.

How stocks tend to react

Listing-day moves are driven by subscription levels and grey-market sentiment, and are notoriously hard to predict. Post-listing, newly listed stocks often stay volatile through their lock-in expiry dates, when pre-IPO investors first become free to sell.

MarketPing measures this instead of guessing: every analysed announcement carries the stock's actual price reaction across 14 horizons, and the Reaction Lab aggregates how each category of announcement has historically moved stocks.
