Two of the year’s biggest India-market stories landed on the same day, and Friday decides what happens next.
Two of the biggest stories in Indian markets this year collided on the same trading day. The Nifty 50 suffered its steepest single-session fall in roughly ten weeks on Thursday, September 24, sliding 383.70 points (1.64%) to close at 23,063.10, dragged down by a regulatory shock that wiped ₹31,426 crore off PB Fintech’s market value in one session.
At the same time, the National Stock Exchange itself completed a decade-delayed transformation from a regulator-adjacent institution to a listed company, debuting in the country’s second-biggest IPO ever.
Friday, September 25, marks NSE’s first full session of price discovery as a public company, a reason to care about today specifically, not just yesterday’s listing headline, alongside a fresh reckoning for insurance stocks and a packed corporate calendar spanning Waaree Energies, Dr Lal PathLabs and more.
Nifty, Sensex Slide as Volatility Spikes 23%
The Sensex fell 1,247.71 points (1.67%) to 73,580.54, while the Nifty Midcap and Smallcap indices dropped a sharper 2.25% and 1.53%, respectively, per Business Standard’s market data.
India VIX jumped 22.76% to close at 12.70. The moves came against a heavier global backdrop: the US 10-year Treasury yield near 5.1%, Brent crude above $100 a barrel, and lingering effects of the Federal Reserve’s September 16 rate hike to 3.75–4.00%, its first increase in three years.
| Index | Close | Change |
|---|---|---|
| Nifty 50 | 23,063.10 | -383.70 (-1.64%) |
| Sensex | 73,580.54 | -1,247.71 (-1.67%) |
| Nifty Midcap | — | -2.25% |
| Nifty Smallcap | — | -1.53% |
| India VIX | 12.70 | +22.76% |
Rupak De, Senior Technical Analyst at LKP Securities, placed immediate Nifty support at 23,000, below which the index could test 22,700, with resistance at 23,200. Track real-time institutional positioning behind such swings on NiftyTrader’s FII-DII Tracker.
PB Fintech’s Record Crash Erases ₹31,426 Crore
The proximate cause was IRDAI’s consultation paper, “Recalibrating Economics of Insurance Distribution”, which proposes shifting the Expenses of Management cap from 30% of Gross Written Premium to 20% of Gross Direct Premium Income over a five-year glide path, alongside differentiated commission caps by segment and channel.
PB Fintech opened at ₹1,697.70 and eventually closed at ₹1,207.20, down 36% and at a fresh 52-week low, its worst single-day fall since its November 2021 listing. The stock’s market capitalisation ended the day at ₹55,863.51 crore.
Co-founder and Group CEO Yashish Dahiya told analysts the proposed structure could cut general-insurance revenue to between one-third and 40% of current levels. Jefferies estimates a 10% commission cut translates to a 10–12% earnings hit for PB Fintech and Turtlemint, which separately hit a 20% lower circuit at ₹109.04, its lowest since its June 2026 listing. Info Edge’s 2.99-crore-share stake in PB Fintech lost roughly ₹1,809 crore of value in the session.
Life insurers Max Financial, ICICI Prudential Life, HDFC Life and SBI Life fell sharply before paring losses; general insurers split, with ICICI Lombard, Go Digit and Star Health closing higher while Niva Bupa and New India Assurance fell about 5%.
Notably, HDFC Mutual Fund bought 25 lakh PB Fintech shares at ₹1,282.30 (~₹321 crore) the same day, a contrarian institutional bet. Kranthi Bathini of WealthMills Securities called the proposal negative for the business; AR Ramachandran of Tips2trades flagged resistance near ₹1,590 on the charts. IRDAI’s feedback window closes October 25, and Bernstein expects strong industry pushback before then.

NSE’s Historic Listing Faces Its First Full Session
Separately, the National Stock Exchange of India completed a listing process that had stalled for nearly a decade amid regulatory hurdles, including the co-location controversy. NSE’s ₹22,561.57-crore IPO, India’s second-largest ever after Hyundai Motor India, was subscribed 5.71 times overall, with the qualified institutional buyer portion booked 12.68 times.
Shares debuted on the BSE on September 24 at ₹1,800, a 0.84% premium to the ₹1,785 issue price, touched an intraday high of ₹1,878, and closed near ₹1,818, valuing the exchange at roughly ₹4.5 lakh crore. Friday marks the first full session of price discovery for one of the world’s largest derivatives exchanges as a public company.

Waaree Energies in Triple Focus
Waaree’s subsidiary WCES announced entry into India’s specialty-gases business on September 24, building a plant at GIDC Saykha, Dahej, to supply ultra-high-purity gases, silane, ammonia, phosphine mixtures and others to semiconductor and solar-cell makers under the Semicon India 2.0 push.
The same week, Waaree secured a 2 GW solar module order for delivery across FY27–28, and its board approved a draft scheme to merge subsidiary Indosolar at a 1:11 share-swap ratio, pending NCLT and shareholder approval.
The stock closed at ₹2,482, down 1.19%, despite the flurry of announcements, a reminder that Thursday’s broad selloff overwhelmed even positive company-specific news.
Dr Lal PathLabs Bets on Genomics; JSW Cement’s Mixed Day
Dr Lal PathLabs approved acquiring a 70% stake in genomics firm SN Genelab for up to ₹168 crore plus a ₹31.5 crore performance earn-out, with the deal expected to close by November 30. SN Gene’s turnover has climbed from ₹43.27 crore in FY24 to ₹57.96 crore in FY26.
JSW Cement received a ₹229.85 crore GST show-cause notice from the Belagavi Audit Commissionerate over alleged misclassification between April 2022 and March 2024, a notice, not a confirmed liability.
The same day, its associate JSW One Platforms filed a DRHP for a ~₹3,054 crore IPO. Motilal Oswal upgraded JSW Cement to Buy from Neutral with a ₹146 target, citing volume growth and cost efficiencies.
Sterlite Technologies Names New M&A Chief as Stock Slips 5%
Sterlite Technologies appointed Lakshmi Iyer, who has executed over $18 billion in transactions across Tata Power, GMR and HCL, as Chief M&A, Investor Relations and Capital Markets Strategy Officer, effective September 23.
It also expanded its Neuralis fibre-trunk portfolio (48F to 6,912F configurations) for hyperscale data centres. The stock still fell 5% to ₹823.75, underscoring how thoroughly the broader selloff dominated Thursday’s tape.
Bharat Dynamics signed an ₹810.79 crore contract with the Ministry of Defence on September 23 for 160 Satellite Smart Anti-Airfield Weapons and associated equipment for the Indian Air Force, with deliveries scheduled across FY28–29, a substantial, ministry-backed order that outweighs several smaller announcements elsewhere on the tape.
Separately, L&T Technology Services announced a partnership with Cognite on September 24 to build joint industrial-AI solutions for asset-intensive industries, establishing a dedicated Centre of Excellence and certifying more than 50 engineers, with its first project already underway with a top-ten global oil and gas company.

Bottom Line
Friday’s session carries two distinct storylines forward: whether Nifty holds the 23,000 support Rupak De flagged, and whether NSE’s first full day as a listed stock brings more profit-booking or fresh buying interest.
On the regulatory side, IRDAI’s October 25 feedback deadline is now the key date for insurance distributors, while Waaree’s Indosolar merger and Dr Lal PathLabs’ SN Genelab deal move into their respective approval pipelines over the coming weeks.
