Keeping ourselves honest

Did the grey market actually get it right?

Every IPO site publishes grey-market premium. Almost none of them ever check it against what happened. Here is the record across the listings this dataset tracks.

Premium before listing, against the actual move

The last grey-market quote recorded BEFORE listing day, against what the stock actually did, across the 23 tracked issues that have both.

Why the grey market is kept in a box →

Hover any point for its name and figures; labels are shown standing only where they fit without overlapping. A point on the dashed line means the premium matched the outcome exactly. Above it the grey market undershot; below it, it overshot. Only quotes recorded strictly before listing day are counted, so a premium quoted once trading had begun cannot flatter the record. This is 23 issues from this dataset alone — far too small a sample to generalise from, and shown to put a number on how much weight the premium deserves rather than to validate it.

How the last few actually did

Issue price against what the stock opened at. This is the only honest scoreboard for everything above it — and the reason we publish our own grey-market record alongside it.

The pipeline

The big ones still to come

Filed with SEBI or publicly confirmed. At this stage most terms genuinely are not set yet — so they show as dashes here rather than as guesses dressed up as data.

The method

A score you are meant to argue with

Most IPO scores are a black box with a verdict attached. Open any pillar of ours and you get the raw metric, the curve it was mapped through, the sub-score and the weight — enough to disagree with the weighting and still trust the arithmetic. Undisclosed data lowers confidence rather than quietly scoring zero, and sentiment is capped at 8 points of 100, so a hot grey market can tilt a score but never carry one.
