BLS Polymers leads today's openers
BLS Polymers, an industrial plastics maker, opens today with a ₹255 crore issue that is entirely a fresh issue — no offer for sale. The price band is ₹142–150, the lot size is 100 shares and the minimum investment is ₹15,000. Proceeds will fund expansion of its Goa manufacturing facility and working capital. The issue closes on Thursday, 29 October, with allotment expected on 30 October and listing on 3 November. Its grey market premium of roughly ₹33–40 (about 22–27% over the ₹150 upper band) makes it the strongest of today's new issues.
SFC Environmental Technologies opens too
SFC Environmental Technologies, a waste-management company, also opens today. Its ₹667.53 crore issue comprises a ₹150 crore fresh issue and an offer for sale of about ₹517.53 crore, priced at ₹313–330 with a 45-share lot (minimum ₹14,850). It follows the same timetable as BLS — close 29 October, allotment 30 October, listing 3 November. Its GMP of roughly ₹21–32 implies a more modest 6–10% listing gain.
EAAA cools further on Day 2
EAAA India Alternatives, which opened yesterday, enters Day 2 after a weak start: it closed Day 1 at just 0.11–0.12x overall (QIB 0.08x, NII 0.33x, retail 0.04x, around 10,161 applications). Its GMP has cooled to about ₹27 this morning, down from ₹35 on 25 October, implying only a ~1.6% premium over the ₹1,665 upper band. The ₹1,200 crore issue, a pure offer for sale, closes tomorrow (28 October) and lists on 2 November.
Core4 Engineers closes today; Wiscon opens
On the SME board, Core4 Engineers closes today after reaching about 0.71x subscription. Wiscon Industries, a consumer-electronics SME issue priced at ₹194–204 with a 600-share lot, opens today and closes on 29 October.
Tomorrow: Jio and Paras list
All eyes are on tomorrow, 28 October, when Jio Platforms lists on the NSE and BSE. The ₹30,213 crore issue — India's biggest IPO — was subscribed 22.19 times, with allotment finalised yesterday. Its GMP of about ₹245 implies an estimated listing price near ₹1,364, roughly 22% above the ₹1,119 upper band. Paras Healthcare, subscribed 2.34 times, also lists tomorrow, but its GMP of about ₹11 points to a near-flat debut around ₹704.
