Market breadth stayed supportive, with Nifty’s midday snapshot showing 39 advancers versus 11 decliners and BSE 100 logging an advance-decline ratio of 2.67x. Insurance and financial names dominated the day’s gainers list, alongside select auto and capital goods stocks.

Large Cap Top Gainers

HDFC Life Insurance Company Ltd (+4.93%) HDFC Life surged as the insurance pack emerged as the clearest leadership group in the session, with multiple listed insurance names featuring among top movers. The move came alongside a sharp drop in India VIX to 12.42 (-5.68%), which typically supports higher-beta financials and encourages fresh risk positioning. Trading activity was elevated, with 99.85 lakh shares changing hands.

Tata Motors Passenger Vehicles Ltd (+4.52%) Tata Motors Passenger Vehicles climbed as auto stocks outperformed, in line with Nifty Auto ending higher (+0.99%) in the broader sectoral scoreboard. The stock also saw heavy participation with 1.30 crore shares traded, signalling strong follow-through buying into the close.

Bharat Heavy Electricals Ltd (+4.39%) BHEL rallied as capital goods and PSU-linked pockets stayed firm, with Nifty CPSE closing in the green (+0.29%) and infrastructure and capex themes holding up through the session. The move was backed by active volumes at 91.28 lakh shares.

SBI Life Insurance Company Ltd (+3.66%) SBI Life gained as insurance remained the standout multi-stock theme for the day, lifting both large-cap and mid-cap life insurers. The stock’s rise reinforced the broader financial sector’s resilience despite weakness in the banking index.

CG Power & Industrial Solutions Ltd (+3.32%) CG Power advanced as investors rotated into capital goods and industrial electrical names during a session that saw broader indices grind higher. Volumes at 25.81 lakh shares supported the up-move, indicating sustained participation rather than a low-liquidity spike.

Mid Cap Top Gainers

Max Financial Services Ltd (+4.61%) Max Financial rose as the life insurance group stayed in focus, mirroring strength in large-cap peers such as HDFC Life and SBI Life during the session. The move came amid supportive market breadth and a lower volatility backdrop, which typically aids rate-sensitive financials. The stock traded 9.82 lakh shares.

Indo-MIM Ltd (+4.45%) Indo-MIM gained as the stock pushed closer to its 52-week high (Rs 1,028.50), keeping momentum traders engaged. The rise was supported by healthy volumes at 22.43 lakh shares, suggesting the move was accompanied by meaningful turnover.

ICICI Prudential Life Insurance Company Ltd (+4.44%) ICICI Prudential Life climbed as insurance remained a consistent outperforming pocket through the day, with multiple insurers featuring among the top gainers list. Volumes of 27.04 lakh shares underlined broad participation in the move.

Apar Industries Ltd (+3.99%) Apar Industries advanced as capital goods and power-linked themes stayed firm, keeping select industrial names in demand alongside BHEL and CG Power. The stock also traded near its 52-week high zone (Rs 18,432.40), which can act as a technical magnet for incremental buying.

GMR Airports Ltd (+3.05%) GMR Airports rose on heavy activity, with 1.17 crore shares traded, pointing to strong positioning in the airports and infrastructure space. The move also tracked the broader mid-cap outperformance, with the BSE Midcap 150 index up 0.83% during the session.

Small Cap Top Gainers

Suratwwala Business Group Ltd (+20.00%) Suratwwala Business Group hit the upper circuit after the company disclosed that its subsidiary, Suratwwala Natural Energy Resource Pvt Ltd, was awarded a 20MWAC/28.1MWDC solar EPC contract. The order value is Rs 69 crore (excluding GST), with O&M pegged at Rs 50 lakh per year and a completion timeline of four months, improving near-term revenue visibility. The stock saw active participation with 7.24 lakh shares traded.

Asian Star Company Ltd (+19.99%) Asian Star jumped to near the upper circuit in thin trading, with the day’s turnover of 2.14 thousand shares standing out versus typically low liquidity referenced in market chatter. With limited free float activity, even modest incremental demand can translate into a sharp percentage move.

Glass Wall Systems (India) Ltd (+19.99%) Glass Wall Systems was locked at a 20% upper circuit and closed at its 52-week high of Rs 258.40, signalling a clean breakout on the chart. The move was accompanied by an outsized 6.75 crore shares in volume, indicating aggressive participation rather than a narrow, illiquid jump.

Crest Ventures Ltd (+16.15%) Crest Ventures climbed sharply in low volumes of 1.83 thousand shares, a setup that often amplifies price changes in small caps when buy orders dominate. The rally also brought the stock closer to its 52-week high (Rs 429.90), keeping momentum interest intact.

Astec Lifesciences Ltd (+14.46%) Astec Lifesciences gained on strong activity, with 10.13 lakh shares traded as the stock extended its recent momentum. Market data cited in the session also indicated the stock trading above its 50-day and 200-day moving averages, a technical setup that commonly attracts trend-following flows.
