Top Losers Today 17-Sep-2026: Key NSE-BSE Laggards

Introduction

Nifty 50 closed at 23,284.15 (up 0.29%) and Sensex ended at 74,406.53 (up 0.09%) on September 17, 2026, even as Nifty Bank bucked the trend to finish lower at 56,161.45 (down 0.23%). Market risk cooled with India VIX down 5.68% to 12.42, pointing to lower implied volatility by the close. The day’s laggards were concentrated in select banking, upstream oil and tech-led counters, reflecting the divergence between benchmark gains and underperformance in pockets of financials.

Large Cap Top Losers

One 97 Communications Ltd (-1.66%) One 97 Communications fell as listed fintech counters corrected on a day when Nifty Bank ended in the red, keeping pressure on the broader financial complex despite headline index gains. The move came with active trading volume of 43.44 lakh shares and after the stock traded relatively close to its 52-week high zone (52-week high: Rs 1,856.50), signalling a pullback from higher levels.

Oil & Natural Gas Corpn Ltd (-1.63%) ONGC slipped as upstream oil names underperformed in a session where the market commentary flagged mixed action in crude-linked stocks, with ONGC lagging even as select heavyweight energy names held up better. The stock also traded near its 52-week low band (52-week low: Rs 227.60), which typically amplifies price sensitivity to sector-level flows.

HDFC Bank Ltd (-1.30%) HDFC Bank declined in line with the underperformance of the banking index, with Nifty Bank closing down 0.23% even as Nifty 50 and Sensex finished higher. High turnover of 2.41 crore shares underscored the stock’s role as a key drag among financial heavyweights, especially with the price still not far from its 52-week low of Rs 682.

Billionbrains Garage Ventures Ltd (-1.19%) Billionbrains Garage Ventures eased as traders reduced exposure in high-volume counters amid selective selling outside the benchmark’s leadership pockets. The stock saw heavy volume of 2.52 crore shares, suggesting the decline was driven more by positioning and liquidity-led moves than by a single, stock-specific trigger in the provided dataset.

Titan Company Ltd (-1.14%) Titan slipped as the market’s sector snapshot highlighted weakness in the diamond and jewellery pocket, where Titan was the key represented name among large caps. The decline also extended the stock’s retreat from its 52-week high of Rs 5,187.45, indicating investors used stronger market conditions to trim exposure in the jewellery segment.

Mid Cap Top Losers

Aditya Infotech Ltd (-5.00%) Aditya Infotech led mid-cap declines, with the fall standing out against an otherwise constructive benchmark close, indicating stock-specific de-risking in the absence of any catalyst in the provided news set. The drop came with 4.74 lakh shares traded and took the stock further away from its 52-week high of Rs 4,094.50.

PB Fintech Ltd (-3.70%) PB Fintech dropped sharply as fintech names corrected alongside weakness seen in One 97 Communications, pointing to a cluster move within the digital financial services space. The sell-off was accompanied by high volume of 72.30 lakh shares and followed a phase where the stock had traded closer to its 52-week high (Rs 1,963.00), setting up a faster pullback when flows turned.

Meesho Ltd (-2.88%) Meesho declined despite broader retailing strength flagged in the market snapshot, suggesting rotation within consumer internet names rather than a blanket sector move. With 81.00 lakh shares traded, the fall reflected active participation and a continuation of the stock’s move away from its 52-week high of Rs 254.65.

Patanjali Foods Ltd (-2.88%) Patanjali Foods fell even as FMCG at the index level was not the weakest pocket, indicating stock-level pressure rather than category-wide selling in the day’s context. The move came on 34.99 lakh shares and kept the price closer to its 52-week low of Rs 328.05 than its 52-week high of Rs 614.65.

Federal Bank Ltd (-2.34%) Federal Bank slid as banking was one of the clear weak spots highlighted by Nifty Bank’s negative close, with heavyweight drags keeping the index lower. The stock’s 55.27 lakh share volume showed sustained selling through the session, consistent with the broader divergence between benchmark gains and banking softness.

Small Cap Top Losers

Euro Pratik Sales Ltd (-14.06%) Euro Pratik Sales saw the steepest cut among the tracked small caps, with the drop pushing the stock closer to its 52-week low of Rs 205 from a 52-week high of Rs 389.95. The move came on 2.39 lakh shares, signalling heavy selling pressure relative to typical small-cap liquidity in the absence of a specific announcement in the provided items.

B-Right RealEstate Ltd (-8.32%) B-Right RealEstate fell sharply in thin trade, with volume of only 3.40 thousand shares implying that limited liquidity likely magnified the downside move. The decline also came after the stock had rallied close to its 52-week high (Rs 1,011.00), setting up a bigger percentage swing when sell orders dominated.

Virat Industries Ltd (-7.46%) Virat Industries declined after the Registrar of Companies, Ministry of Corporate Affairs approved the company’s name change to Brahm Virat Industries Corporation Limited effective September 15, 2026, as per the provided context. The market reaction suggested a sell-on-news move, with the stock extending weakness even after the corporate action update.

Shiv Texchem Ltd (-7.46%) Shiv Texchem dropped as the stock continued to trade well below its 52-week high of Rs 292, and the day’s move indicated a fresh leg of selling rather than a minor dip. With just 5.60 thousand shares traded, the price action points to small-cap volatility where relatively small order flow can drive outsized percentage changes.

Monolithisch India Ltd (-6.82%) Monolithisch India retreated as investors pared exposure after a strong run-up over the past year, with the stock still far above its 52-week low of Rs 367 and near the upper end of its 52-week range. The provided context also flagged a high valuation multiple (P/E near 100.94x), and the decline on 46.00 thousand shares indicated profit-taking at elevated levels.

Market Overview

Indian equities ended higher on September 17, 2026, with Nifty 50 up 0.29% at 23,284.15 and Sensex up 0.09% at 74,406.53, while volatility eased as India VIX dropped 5.68% to 12.42. The session was characterised by rotation rather than a uniform rally, with finance and retailing showing leadership at points during the day, while banking and select IT names remained the clearest weak pockets.

The divergence was most visible in the banking space, where Nifty Bank closed lower (down 0.23%) and heavyweight names such as HDFC Bank stayed under pressure, limiting the market-cap-weighted rise even when broader participation improved. In commodities, the day’s snapshot described mixed crude-linked action, with ONGC among the notable laggards.

Market breadth indicators in the provided context were constructive earlier in the session, including an early advance-decline count of 33 advances versus 17 declines and a stronger midday picture of 39 advances versus 11 declines among tracked constituents. That breadth, alongside a lower VIX, helped benchmarks stay positive even as a handful of large stocks and several high-beta mid and small caps featured among the day’s top losers.
