Introduction

Nifty 50 closed at 24,287.65, down 78.35 points or 0.32% on 18 Aug 2026, while Sensex also ended lower, falling over 300 points as IT stocks dragged broader indices. Market breadth within the Nifty basket stayed weak with 16 advancing stocks against 32 declining and 2 unchanged, translating into an advance-decline ratio of 0.50. Despite the headline decline, pockets of strength showed up in auto and ancillaries, pharma and healthcare, crude oil and power, which helped several non-IT names finish among the day’s top gainers.

Large Cap Top Gainers

Bosch Ltd (+3.79%) Bosch rose as investors added exposure to the automobile and ancillaries pocket, which held up better than the broader market in a session led lower by IT. The stock also traded close to its 52-week high zone, with 48,700 nearing the 52-week high of 48,924.15, encouraging momentum buying.

Vodafone Idea Ltd (+3.07%) Vodafone Idea gained on exceptionally heavy participation, with 84.86 crore shares traded, signalling a high-conviction trading session in the counter. With no stock-specific news provided, the move appeared driven by activity-led momentum as the price moved closer to its 52-week high of 15.35.

Torrent Pharmaceuticals Ltd (+1.63%) Torrent Pharma advanced as money rotated into pharma and healthcare counters even as benchmark indices declined, supported by the broader defensive tilt mentioned in today’s sector snapshot. The move came alongside strength in other pharma names, with steady volumes of 4.41 lakh shares.

Divi’s Laboratories Ltd (+1.24%) Divi’s Laboratories climbed as investors favoured defensives amid across-the-board weakness in IT, with pharma and healthcare among the sectors showing relative outperformance. The stock’s rise also kept it near its 52-week high region of 8,670.50, reinforcing the near-peak trend.

Tata Capital Ltd (+1.21%) Tata Capital rose in a session where the finance group showed pockets of support, aided by gains in large financials such as Axis Bank and Bajaj Finance in the broader market context. With no company-specific trigger provided, the uptick tracked the selective bid in financial names, supported by 9.11 lakh shares traded.

Mid Cap Top Gainers

Indo-MIM Ltd (+10.00%) Indo-MIM hit a sharp upmove as the stock printed its 52-week high at 951.30, matching the day’s close and signalling a breakout. The move was backed by very high traded volume of 1.07 crore shares, pointing to strong incremental demand chasing the new-high setup.

Tube Investments of India Ltd (+8.61%) Tube Investments jumped as investors accumulated auto-linked names, with automobile and ancillaries noted among the day’s better-performing groups despite weak benchmarks. The rally also coincided with heavy volume of 43.96 lakh shares, suggesting follow-through buying rather than a thin trade.

GlaxoSmithKline Pharmaceuticals Ltd (+6.79%) GSK Pharma rose as pharma and healthcare counters attracted defensive flows on a day when IT was the clearest sector laggard. The stock traded near its recent peak, ending at 2,883.20 against a 52-week high of 2,918, with 5 lakh shares changing hands.

Aegis Logistics Ltd (+6.65%) Aegis Logistics gained in line with strength in crude oil and related value-chain names, with the broader crude oil group in the market context up 0.62%. Volumes of 32.49 lakh shares reinforced the move, indicating meaningful participation as the stock held near its intraday strength.

Apar Industries Ltd (+4.16%) Apar Industries advanced as power and allied themes stayed firm, with the power group in the market snapshot up 0.38% and full participation from key index power names. The stock’s move came on steady volume of 3.58 lakh shares, aligning with continued interest in electrical and grid-linked plays.

Small Cap Top Gainers

Supreme Power Equipment Ltd (+19.98%) Supreme Power Equipment surged after the company filed its Q1 FY27 investor presentation reporting about 32% to 37% YoY revenue growth and net profit of about Rs 4.90 crore. Investors also reacted to the disclosed consolidated order book of about Rs 590.06 crore, which strengthens revenue visibility for an equipment maker.

Subex Ltd (+16.97%) Subex jumped on a momentum-led move that pushed the stock up to its price band ceiling during the session, with the counter seeing very heavy volume of 4.91 crore shares. With no verified company news provided, the key driver was a technical breakout towards the 52-week high zone of 16.89, with buying strong enough to keep prices near the day’s highs.

E to E Transportation Infrastructure Ltd (+15.72%) E to E Transportation Infrastructure rallied as the stock extended its recent uptrend and drew fresh participation, evident from 6.43 lakh shares traded. In the absence of a specific news trigger in the provided data, the move aligns with a strong momentum setup as the price moved closer to its 52-week high of 347.10.

Prabha Energy Ltd (+15.02%) Prabha Energy spiked amid unusually high trading activity versus its recent baseline, with the broader context noting the counter featuring among BSE ‘B’ group gainers and volume far above its one-month average in the cited market snapshot. With no company announcement provided, the sharp move appears driven by liquidity and order-flow dynamics in an otherwise thinly traded name.

Alpex Solar Ltd (+12.73%) Alpex Solar climbed after reporting strong Q1 FY27 results, with consolidated operating revenue of Rs 503.42 crore, up 32.37% YoY, EBITDA of Rs 78.43 crore and PAT of Rs 39.86 crore (EPS Rs 15.61). The company’s update that its cell plant is ready and that it has filed its MNRE ALMM application added to expectations of execution-led growth in the solar manufacturing theme.

Market Overview

Nifty 50 ended at 24,287.65, down 78.35 points or 0.32%, extending a weak run in benchmarks, while Sensex also finished in the red with a decline of over 300 points as heavyweights in IT weighed on the tape. Within the Nifty constituent snapshot shared in the market context, breadth stayed negative with 16 gainers, 32 losers and 2 unchanged, keeping the advance-decline ratio at 0.50.

Sector leadership remained mixed. IT was the weakest multi-stock group, down 1.68%, with all five key constituents in the red, led by declines in Infosys, HCL Technologies and Tech Mahindra. On the other hand, crude oil (up 0.62%), power (up 0.38%), automobile and ancillaries (up 0.30%) and finance (up 0.29%) held up better, helping select auto, pharma, oil-linked and power-adjacent names appear among the day’s gainers even as indices slipped.

FII and DII flow data was not provided in today’s input. The session’s overall pattern pointed to stock-specific moves and defensive rotation, with earnings-led rallies in select small caps and breakout trades in a few mid and small-cap counters.
