Summary:
Indian markets traded largely flat on June 4, but several stocks witnessed sharp movements driven by company-specific developments and sector trends. PhysicsWallah, Zen Technologies and Tejas Networks emerged as top gainers, supported by strong volumes and positive business outlook. Meanwhile, Zensar Technologies, NALCO and Ather Energy were among the biggest losers as investors booked profits and reacted to sectoral weakness.
Indian equity benchmarks traded largely flat on June 4 as investors remained cautious ahead of the Reserve Bank of India’s monetary policy decision and monitored rising geopolitical tensions between the United States and Iran. The Nifty 50 gained 0.1%, while the Sensex rose 0.06% during morning trade.
Despite the muted market sentiment, several Nifty 500 stocks witnessed sharp moves driven by company-specific developments and sectoral trends.
PhysicsWallah Surges 18%
PhysicsWallah, an education technology company offering online and offline learning solutions, emerged as the top gainer in the Nifty 500 index. Its shares jumped 18% as trading volume surged to 1.24 crore shares, more than double the 30-day average.
The rally followed the company's decision to invest around ₹120 crore in its wholly-owned subsidiary FinZ Finance and adopt an asset-light lending model through partnerships with third-party NBFCs. The move is expected to reduce balance sheet and credit risks. Investor sentiment was also supported by improving financial performance, with FY26 revenue rising to ₹3,900 crore from ₹2,887 crore a year earlier, while losses narrowed significantly to ₹24 crore.
Zen Technologies Gains 12%
Zen Technologies, a defence technology company specializing in military training simulators and anti-drone solutions, gained 12% with strong trading activity. Volumes rose to 26.77 lakh shares compared to the 30-day average of 9.19 lakh shares.
There was no immediate company-specific trigger behind the rally. However, positive sentiment continues after the company launched India’s first modular AI-powered counter-drone system in May. Strong quarterly earnings and growing investor interest in defence stocks also supported the move. In the absence of fresh news, the gain appears largely driven by market demand and sector momentum.
Tejas Networks Extends Rally
Tejas Networks, the Tata Group-backed telecom equipment manufacturer, rallied 10% and extended its winning streak to five consecutive sessions. The stock has gained around 25% during this period.
Volumes remained strong at 1.2 crore shares against the 30-day average of 83.5 lakh shares. Investors are betting on a stronger FY27 after a difficult FY26, when delays in major projects hurt performance. Revenue fell sharply and the company reported a net loss, but a growing order book and expectations of improved execution have boosted sentiment.
Zensar Technologies Among Top Losers
Zensar Technologies, an IT services and digital transformation company, declined 4.91% to ₹484.70.
No major company-specific development was reported. The decline appears to be linked to weakness in the broader IT sector, concerns over global technology spending and profit booking in mid-cap technology stocks. The movement was largely driven by market forces rather than any fresh negative trigger.
NALCO Falls Over 4%
National Aluminium Company (NALCO), one of India’s leading aluminium producers, dropped 4.17% to ₹418.70.
The weakness was attributed to pressure in the metals sector, concerns over softer alumina prices and profit booking after recent gains. There was no major company-specific announcement behind the decline.
Ather Energy Slides 4%
Ather Energy, an electric two-wheeler manufacturer, fell 4.01% to ₹981.10.
Despite reporting improving operational performance in recent quarters, the stock witnessed profit booking. With no fresh negative developments, the decline appears to be driven by valuation concerns and broader market volatility.
Conclusion
Stock-specific action dominated trading on June 4. PhysicsWallah, Zen Technologies and Tejas Networks led the gainers on strong volumes and positive business expectations. Meanwhile, Zensar Technologies, NALCO and Ather Energy were among the top losers, with declines largely driven by sectoral weakness, profit booking and broader market sentiment rather than significant company-specific developments.
