Top Gainers Today 12-Aug-2026: NSE, BSE movers

Introduction

Nifty 50 closed at 24,471.70 (-0.46%) while the BSE Sensex slipped 388.19 points to 78,154.25 (-0.49%) on 12 Aug 2026, as higher crude prices and geopolitical uncertainty kept benchmarks under pressure. Despite the weak close, the day’s top gainers were dominated by PSU financials (PNB, Union Bank, Bank of Maharashtra), industrials and power-linked names (BHEL, TD Power Systems), and commodity-linked plays (NALCO). Advance-decline data and FII/DII flow numbers were not provided in the input.

Large Cap Top Gainers

Vodafone Idea Ltd (+4.49%) Vodafone Idea climbed on unusually heavy trading volumes of 82.46 crore shares, signalling a momentum-driven move in a low-priced large-cap counter. The stock’s rise came as traders pushed it closer to its 52-week high zone (₹15.35), which typically draws incremental participation from short-term strategies tracking breakouts.

Punjab National Bank (+3.87%) Punjab National Bank rose alongside other PSU banking names in the day’s gainers list, indicating sector-led buying rather than a stock-specific announcement in the provided data. Strong volumes of 5.29 crore shares underscored active positioning in liquid PSU financials even as benchmarks ended lower.

Bharat Heavy Electricals Ltd (+3.87%) BHEL advanced as power and capital-goods names remained in focus, with investors favouring domestically oriented industrial plays despite headline index weakness. The move was accompanied by 1.57 crore shares in volume, supporting the view that the up-move was backed by broad participation.

Life Insurance Corporation of India (+2.77%) LIC gained with above-average activity (2.22 crore shares), as investors rotated into large, liquid financial counters that can act as defensive allocations on a down day for the indices. With the stock still below its 52-week high of ₹468.30, the move also reflected a rebound attempt within its recent trading range.

Union Bank of India (+2.39%) Union Bank of India climbed in line with the PSU banking pack, which featured prominently among the day’s top gainers across market caps. Volumes of 2.30 crore shares suggested the move was driven by active trading and sector-level flows rather than a discrete corporate update in the supplied news.

Mid Cap Top Gainers

National Aluminium Company Ltd (+7.89%) NALCO surged as metal-linked names featured among index gainers in the session’s broader tape, with the provided market context showing Hindalco up over 3% intraday. The sharp jump also came with strong volumes of 3.60 crore shares, indicating a sector-driven move where investors preferred commodity producers even as the benchmarks closed in the red.

Apar Industries Ltd (+7.58%) Apar Industries rallied as the stock moved closer to its 52-week high (₹18,432.40), a setup that often triggers buying from trend-following strategies in high-priced mid-caps. The move was supported by 4.30 lakh shares in volume, pointing to sustained demand through the session.

Berger Paints India Ltd (+4.33%) Berger Paints climbed on notable volumes of 19.14 lakh shares, suggesting investors used the session to add to a liquid consumer-facing mid-cap despite the broader pressure on FMCG noted in the market context. With no specific corporate headline provided, the price action points to a technical rebound with active participation.

Bank of Maharashtra (+3.80%) Bank of Maharashtra extended gains as PSU banks dominated the day’s leadership list across large and mid caps, indicating sector rotation into state-owned lenders. Heavy volumes of 2.79 crore shares reinforced that the move was flow-led and not merely a low-liquidity spike.

Gujarat Fluorochemicals Ltd (+3.52%) Gujarat Fluorochemicals gained as it traded near its 52-week high of ₹4,695, keeping it on breakout watch for short-term traders. Volumes of 10.07 lakh shares provided additional confirmation that the move was supported by market participation.

Small Cap Top Gainers

Singer India Ltd (+20.00%) Singer India hit the 20% upper circuit, with volumes jumping to 27.40 lakh shares as the stock moved close to its 52-week high of ₹95.70. With no verified database headline provided for the session, the move appears to have been driven by a liquidity-led breakout attempt, where the sharp price rise itself pulled in incremental trading interest.

Delton Cables Ltd (+20.00%) Delton Cables locked in a 20% upper circuit a day after reporting strong Q1 FY27 numbers, including revenue of ₹2,863.6 million (+83% YoY), EBITDA of ₹254.3 million (8.88% margin) and PAT of ₹75.9 million (+146% YoY). Investors also reacted to management’s disclosure around the order book, which stood at ₹418 million as of June 30, 2026, and to the corporate actions timeline (record date set for a final dividend, subject to AGM).

TCPL Packaging Ltd (+19.93%) TCPL Packaging surged after announcing Q1 FY2027 results and a strategic expansion into lithium-ion battery separator films via a proposed subsidiary. The company reported Q1 total income of ₹494.9 crore (+15.9% YoY) and PAT of ₹40.0 crore (+79%), alongside plans for capacity expansion and an estimated ~₹125 crore investment for the new battery-separator business, while its AGM outcome also included a dividend of ₹25 per share. The stock traded near its 52-week high (₹4,429.55), amplifying momentum.

TD Power Systems Ltd (+15.87%) TD Power Systems jumped after it reported Q1 (ended 30-06-2026) results with net sales of ₹62,784.19 lakh and PAT of ₹8,646.36 lakh, providing a clear earnings trigger for the re-rating move. The rally was accompanied by very high activity (1.20 crore shares) and pushed the stock close to its 52-week high of ₹1,529, while the company also notified that its board will consider a fund-raising proposal on 14 Aug 2026.

Emerald Leisures Ltd (+14.33%) Emerald Leisures rose sharply as the stock moved toward its 52-week high of ₹264.95, with small-cap price action indicating a momentum-led extension. As supplementary context provided, the counter has also been in focus following a reported INR 1.05 billion private credit investment (dated 05 Aug 2026 in the supplied context), which can act as a near-term attention driver in micro and small-cap names.

Market Overview

Benchmark indices ended lower on 12 Aug 2026, with Nifty 50 closing at 24,471.70 (-0.46%) and Sensex at 78,154.25 (-0.49%). The provided market context attributed the pressure to rising crude oil prices amid geopolitical uncertainty, a combination that typically raises input-cost concerns and weighs on risk appetite.

Sectorally, the session saw weakness flagged in IT, FMCG and realty in the supplied tape, while select pockets such as metals and PSU financials showed strength in the day’s movers. That divergence was visible in the market movers list, where aluminium-linked NALCO topped mid-cap gainers and multiple state-owned banks featured across large and mid caps.

FII/DII flow data and an exchange-level advance-decline ratio were not available in the input, so intraday leadership is best read through the concentration of gainers in PSU financials, industrials, and select commodity-linked counters.
