Listing-day scorecard: 3 November 2026
| IPO | Issue price | Listing price (NSE) | Close (3 Nov) | Gain at close |
|---|---|---|---|---|
| BLS Polymers | ₹150 | ₹248 (+65.3%) | ₹268.80 (NSE) / ₹269.30 (BSE) | ~79–80% |

BLS Polymers: blockbuster debut beats grey-market expectations
BLS Polymers listed at ₹248 on the NSE — a 65.33% premium over its ₹150 issue price — and ₹244.10 on the BSE (+62.73%). The stock kept climbing through the session and closed at ₹268.80 on the NSE and ₹269.30 on the BSE, a gain of roughly 79–80% over the issue price. One allotted lot of 100 shares, costing ₹15,000, was worth about ₹26,880–26,930 at close.
The debut beat grey-market expectations: ahead of listing, the unofficial GMP was around 45–46%, implying a far smaller opening gain than the 65% actually delivered. The ₹255-crore issue was entirely a fresh issue of 1.7 crore shares, priced in a ₹142–150 band, and was subscribed 241.22 times — driven by strong non-institutional demand. According to exchange data, about 793 lakh BLS shares changed hands on listing day, worth over ₹2,100 crore.
SFC Environmental Technologies: steady open, circuit close
SFC Environmental Technologies listed at ₹355.10 on the NSE (+7.61%) and ₹354.05 on the BSE (+7.29%) against its ₹330 issue price, broadly in line with its unofficial grey-market premium of around 5%. Buying continued through the day and the stock closed at its upper circuit — ₹426.10 on the NSE and ₹424.85 on the BSE — a gain of about 29% over the issue price. One allotted lot of 45 shares (₹14,850 at issue price) was worth roughly ₹19,100 at close.
The ₹667.53-crore issue (₹150 crore fresh issue plus a ₹517.53-crore offer for sale) was subscribed about 9.47 times. The Navi Mumbai-based company provides technology, design, engineering and commissioning solutions for wastewater treatment, recycling and reuse, and solid-waste treatment.
Wiscon Industries: flat listing, marginal slip
Wiscon Industries debuted on the BSE SME platform at ₹204, exactly matching its issue price, and drifted marginally lower to close around ₹203.55 — a fall of roughly 0.2%. The ₹110-crore SME issue, priced in a ₹194–204 band, had closed at about 1.15 times subscription, with the weakest demand of the three debutants — which showed up in its flat listing.
