IRCON (NSE: IRCON), Reliance Infra (NSE: RELINFRA), Servotech (NSE: SERVOTECH) lead Indian stock market gainers

Indian equities roared back to strength on June 4, 2025, with benchmark indices rallying over 1.5% amid strong institutional buying, cooling crude prices, and sector-specific momentum in public sector undertakings (PSUs), clean energy, and legal-deleveraging stories.

The NSE Nifty 50 closed 1.6% higher at 23,262.70 while the BSE Sensex gained 1,125 points to finish at 76,940. Mid- and small-cap segments outperformed sharply, with the Nifty Midcap 100 rising 2.3% and Smallcap 250 adding 2.6%. Notably, nine of the top ten NSE gainers were midcap names with sector exposure to infrastructure, EV components, or digital public infrastructure.

Why Did IRCON (NSE: IRCON) Stock Jump 14% on June 4, 2025?

IRCON International Ltd. surged 14% to close at ₹221.10, logging over ₹1,620 crore in traded turnover. The PSU engineering giant rallied following reports of new project awards from the Indian Railways and neighboring countries, aligning with the government’s Q1FY26 capital expenditure drive.

In its March quarter, IRCON reported consolidated revenues of ₹2,761 crore and net profit of ₹240 crore, supported by robust execution in domestic EPC contracts. The company has a visible order book of over ₹40,000 crore, with exposure to both Indian and foreign railway infrastructure. Brokerage commentary has turned favorable, citing a possible re-rating closer to peers like Rail Vikas Nigam Ltd. (NSE: RVNL).

Some analysts have highlighted the “renewed relevance of PSU infra stocks” amid capital allocation clarity from the FY26 interim budget. Investor flows were heavy from both DIIs and retail-algo desks, with delivery volumes exceeding 65%.

What Triggered Reliance Infrastructure (NSE: RELINFRA) Stock to Rally Over 11%?

Reliance Infrastructure Ltd., part of the Anil Ambani group, surged 11.11% to ₹380.05 after the NCLAT suspended insolvency proceedings initiated by the NCLT a week earlier. The appellate court’s ruling provided legal clarity and near-term solvency relief, reigniting institutional interest in the embattled infra conglomerate.

The company’s standalone revenue for FY25 stood at ₹6,204 crore, though it has struggled with high leverage and legal claims. The positive court development sparked short covering and technical long entries, particularly in the derivatives segment, where open interest fell sharply.

Market participants noted heavy buying by HNIs and arbitrage funds, betting on asset monetization and arbitration windfall scenarios, especially around stalled airport and EPC projects.

Why Did Servotech Power Systems (NSE: SERVOTECH) Stock Gain 14%?

Servotech Power Systems Ltd. closed 14% higher at ₹162.30 after investor attention returned to India‘s EV infrastructure push. The company, a key player in solar inverters and EV charging systems, was highlighted in a Samayam Business report as a 6,500% multibagger over the past 5 years, further attracting momentum traders.

In FY24, Servotech posted ₹287 crore in revenue with a net profit of ₹24 crore and strong operating margins of 12.6%. Its recent MoU with NTPC for nationwide EV charger deployment has sparked optimism about scaling beyond Tier 1 cities.

Investor desks at Kotak Institutional Equities noted Servotech as a “high-RoCE niche midcap play” with scope for re-rating, especially as green energy capex themes intensify post-election.

What Caused RailTel (NSE: RAILTEL) Stock to Surge Over 12%?

RailTel Corporation of India Ltd., a digital PSU under the Ministry of Railways, jumped 12.03% to ₹446.95. The stock’s upward move followed high-volume block deals and renewed expectations that RailTel will play a bigger role in BharatNet’s upcoming Phase III expansion.

For FY24, RailTel reported ₹2,158 crore in top line and ₹258 crore in profit, reflecting its strong broadband footprint across India’s Tier 2/3 geographies. Analysts have reaffirmed a BUY rating with a target of ₹510, citing improved bandwidth monetization and robust PSU contract flow visibility.

Delivery-based buying accounted for over 62% of traded volume, with active participation from thematic mutual funds.

Why Did Zim Laboratories (NSE: ZIMLAB) Stock Rise 13.8%?

Zim Laboratories Ltd. climbed 13.83% to ₹102.00 despite no formal news release. The pharma midcap has benefited from speculation around government procurement cycles and WHO-related dossier expansion in oral dissolvable formulations (ODFs), a core R&D strength for the company.

In FY24, ZIMLAB posted ₹234 crore in revenue and ₹19 crore in PAT. Its export-heavy pipeline and niche regulatory focus make it a small-cap favorite during low-float rotations. Technical charts also showed a clear breakout from a descending channel, encouraging short-term positional entries.

Exxaro Tiles (NSE: EXXARO) Climbs 12% on Margin Expansion Buzz

Exxaro Tiles Ltd. rose 12.09% to ₹8.90 on June 4 after trading volumes rose 8x the 30-day average. While no filings were made, investor sentiment was buoyed by speculation on lower gas prices and improved ceramic tile exports to the Middle East.

For FY24, the company recorded ₹362 crore in revenue with a net loss of ₹6 crore, but margin headwinds may be easing. Analysts anticipate a Q2FY26 margin rebound if raw material inputs like zircon and energy continue to correct.

Quick Heal Technologies (NSE: QUICKHEAL) Gains 17.2% on Cybersecurity Buzz

Cybersecurity solutions provider Quick Heal Technologies Ltd. was the top gainer of the day, soaring 17.24% to close at ₹352.00. The move came after unconfirmed reports suggested an increase in MeitY-backed cybersecurity allocations and renewed public sector deal flow.

Quick Heal’s FY24 earnings stood at ₹308 crore in revenue and ₹32 crore in net profit, with improved product penetration in government verticals. Volume spiked to 50.4 million shares on the NSE, indicating strong institutional and retail crossover.

Gencon Powertech and MVGJL Stocks See Double-Digit Spikes

Gencon Powertech Ltd. rose 14.72% to ₹42.25 after it secured a ₹300 crore EPC contract from a South Indian utility board, per exchange disclosure. The firm’s low-float nature combined with capex-linked growth themes made it an intraday favorite.

MVGJL (Manaksia Viniyog Ltd.) added 13.95% to ₹269.05, with momentum traders betting on rotation into SME metals and holding company plays after a prolonged consolidation.

PURVA (NSE: PURVA) Stock Climbs on New Project Announcements

Puravankara Ltd. (NSE: PURVA) gained 9.99% to ₹279.00 after the company announced four new residential projects with a cumulative GDV of ₹3,500 crore across Bengaluru and Pune.

The realty firm reported FY24 revenue of ₹1,915 crore and net profit of ₹212 crore. ICICI Direct and Axis Securities have both upgraded PURVA in recent weeks, citing strong pre-sale visibility and improved leverage ratios.

Institutional Sentiment: FIIs Return, Block Trades Surge

FIIs were net buyers of ₹3,200 crore on June 4, reversing a week-long cautious trend. Notable block deals were reported in Quick Heal, RailTel, and IRCON. Domestic mutual funds saw ₹1,450 crore in gross purchases, particularly in infra and small-cap pharma names.

Short interest declined in six of the top ten gainers, suggesting short-covering played a role in amplifying upside in names like RELINFRA and ZIMLAB.

Future Outlook: RBI Decision, Fed Commentary and Monsoon to Guide Next Leg

Investors now await the RBI’s June policy review, where rates are expected to remain unchanged. However, commentary on inflation, liquidity, and FX management will be critical for short-term flows. Globally, the upcoming U.S. jobs report and Fed speak may sway risk-on appetite.

Sectors like capital goods, PSUs, and real estate could continue outperforming as fund managers rotate into domestic-centric growth names. Analysts expect continued M&A buzz in infra-EPC and digital infra domains through Q2FY26.
