This issue listed on 24 Sep 2026 — grey-market quoting band ho chuki hai. Final unofficial premium +₹49 (+2.7%) tha, actual debut +1.9% debut gain. Compare the two to judge how honest the street signal was.
National Stock Exchange of India commands a grey-market premium of ₹49 (+2.7% of the ₹1785 upper band), about ₹392 per lot of 8 shares. Street demand is cooling: the quote slipped from ₹143 to ₹49 across 2 tracked sessions — late-window weakness often precedes a soft debut. Books show 5.71x total subscription (QIB 12.68x, NII 6.55x, retail 1.39x). Institutions are carrying this issue — QIB demand near 12.68x is the smart-money leg that grey quotes usually follow, not lead. At ₹22,563 Cr this is a heavyweight issue — large floats absorb grey-market heat faster, so premiums here move slower than SME pops. This issue has already listed — compare the debut against the premium trail above to judge how honest the street signal was.
Unofficial street quote — treat as sentiment alongside subscription breadth and fundamentals, never as a promised listing price.
