Indian benchmark indices opened lower on Tuesday, August 25, weighed down by a tech-driven selloff on Wall Street, rising geopolitical tensions involving the US and Iran, and caution ahead of upcoming earnings reports. Meanwhile, Tata Consultancy Services drew market attention following a major acquisition and strategic partnership announcement.

Mumbai: Benchmark indices opened lower on Tuesday, August 25, weighed down by a tech-driven selloff on Wall Street, escalating US-Iran tensions, and cautious sentiment ahead of Nvidia's earnings. The Sensex opened at 77,295.49 and traded down 36.87 points at 77,332.24 as of 9:23 AM, following a previous close of 77,369.11. The Nifty 50 opened at 24,175.75 and stood at 24,177.90, down 41.15 points.

The domestic weakness follows Monday's session where the Nifty shed 32.95 points as gains in metals and IT were offset by selling in financials and PSU banks. Shrikant Chouhan, Head of Equity Research at Kotak Securities, noted that a bearish candle on the daily charts points to ongoing pressure, identifying 24,250 and 77,500 as immediate resistance zones for bulls.

Globally, markets reacted to US Treasury Secretary Scott Bessent announcing a sanctions campaign against Iran, which drove demand for safe-haven assets and pushed Brent crude near $90 a barrel. Gold and silver traded at three-month highs, while Asian markets opened weaker following an overnight semiconductor selloff on Wall Street that dragged down the Nasdaq and S&P 500.

Among Nifty 50 stocks, Eternal, Trent, Adani Ports, TCS, and SBI Life Insurance opened higher. Conversely, top laggards included Cipla, Hindalco, TMPV, Maruti Suzuki, and Tata Consumer Products.

In corporate developments, TCS remained in focus after announcing a €320 million deal to acquire Porsche AG's management and IT consulting arm, MHP, alongside a five-year strategic partnership worth approximately $1.46 billion. Ponmudi R, CEO of Enrich Money, stated that IT stocks are likely to remain in focus following the announcement.

On the institutional front, foreign institutional investors turned net buyers on Monday by purchasing equities worth ₹1,181 crore, while domestic institutional investors extended their buying streak to a tenth consecutive session with investments totaling ₹2,493 crore. Hitesh Tailor, Technical Research Analyst at Choice Broking, remarked that strong domestic inflows may offer a cushion, though volatility is expected to remain elevated.

Tuesday also marks the first monthly derivatives expiry using the Closing Auction Session mechanism. Market analysts, including Devarsh Vakil, Rajesh Palviya, and Gaurav Udani, have advised traders to maintain a cautious, level-based approach and avoid aggressive positions amidst opening volatility.

"The current market behavior highlights the delicate balance between domestic institutional support and external macroeconomic headwinds. While geopolitical tensions and global tech selloffs create short-term volatility, large strategic transactions, such as TCS's acquisition of MHP, demonstrate the long-term resilience and global ambitions of Indian enterprises. Investors and business leaders must navigate these dual dynamics with disciplined risk management rather than reacting to short-term market swings." — Dr. Shishir Gupta, Founder & CEO, StartupLanes
