On Tuesday, September 29, the 30‑share BSE Sensex fell 242.65 points or 0.33% to close at 72,529.07, while the 50‑share NIFTY50 slipped 64.05 points or 0.28% to finish at 22,716.20. The indices were in negative territory for the second consecutive session, with the Sensex dropping as much as 0.97% to an intraday low of 72,064 and the NIFTY50 falling 0.92% to a session low of 22,569.65. The decline was driven by a surge in global crude oil prices, foreign institutional investor (FII) outflow, and a weak rupee that weakened past the 96 mark during the trading session.

Foreign institutional investors sold shares worth ₹5,353.22 crore on Monday, while domestic institutional investors purchased equities worth ₹5,189.02 crore on a net basis, according to exchange data. The rupee’s depreciation and the oil‑price rally contributed to the market’s negative sentiment. The Sensex and NIFTY50 were both affected by the broader macro‑economic backdrop, with the rupee falling below 96 and global oil prices climbing, prompting a cautious stance among investors.

In the NIFTY50, the top losers were Titan Company (-3%), Wipro (-2.95%), HCL Technologies (-2.44%), Apollo Hospitals Enterprise (-2.27%) and Tech Mahindra (-2.06%). The top gainers included Adani Enterprises Ltd (5.01%), Adani Ports and Special Economic Zone (4.49%), Dr. Reddy's Laboratories (2.53%), Sun Pharmaceutical Industries (1.47%) and Infosys (1.22%). Shares of Adani Enterprises and Adani Ports rose as the group settled a ₹1.48 crore settlement with SEBI over alleged violations of minimum public shareholding norms.

The settlement covered Adani Enterprises Ltd, Adani Power Ltd, Adani Ports and Special Economic Zone Ltd and Adani Transmission Ltd, now Adani Energy Solutions Ltd, along with their directors. The proceedings stemmed from complaints received by SEBI in June and July 2020 alleging non‑compliance with minimum public shareholding requirements by certain listed Adani Group companies. The resolution of these proceedings was reflected in the share price gains for the Adani Group companies.

The NIFTY Midcap 100 closed 0.99% lower at 59,319.40, dragged down by PB Fintech, which settled 6.11% lower, followed by Patanjali Foods (-4.96%), Coromandel International (-4.69%), Voltas (-4.01%) and Premier Energies (-3.97%). On the upside, Glenmark Pharmaceuticals rose 4.98%, Mankind Pharma 4.49%, Vishal Mega Mart 3.49%, BSE 3.31% and Lenskart Solutions 3.01%. BSE shares rose as investors anticipate potential fund inflows due to the upcoming NIFTY50 semi‑annual index rebalancing on September 30.

The NIFTY Smallcap 100 ended at 19,193.55, down 157.55 points or 0.81%. The top losers were Amber Enterprises India (-5.49%), Kfin Technologies (-5.19%), Five‑Star Business Finance (-5.05%), Whirlpool of India (-3.90%) and Tata Chemicals (-4.47%). Tata Chemicals fell after Tata Trusts proposed a restructuring of Tata Sons that could allow the holding company to remain private and avoid a stock‑market listing. The restructuring would merge Tata Electronics Systems Solutions Pvt Ltd and Tata Consulting Engineers with Tata Sons, changing the composition so the reorganised entity would no longer meet regulatory criteria for a non‑banking financial company or a core investment company. The top gainers were Welspun Corp (3.26%), Gland Pharma (3.07%), HBL Engineering (2.97%), Meesho (2.61%) and Delhivery (2.43%).
