Top Gainers Today 01-Oct-2026: Infosys, Molbio rally

Introduction

Nifty 50 closed at 22,335.35 (-1.26%) and the Sensex ended at 71,669.31 (-1.12%) on 01 Oct 2026, even as select IT and defensives featured among the day’s top gainers. Market breadth was sharply negative, with only 48 stocks advancing against 452 decliners in the BSE500, signalling broad-based risk-off positioning. From the gainers list, IT (Infosys, Mphasis, Coforge) and power and electrical equipment names (Siemens Energy India, Hitachi Energy India, Viviana Power Tech) stood out despite the broader sell-off. Foreign investor activity remained a key overhang, with the market context pointing to continued FII selling in the run-up to this session.

Large Cap Top Gainers

Infosys Ltd (+4.02%) Infosys climbed as IT stocks bucked the broader market weakness, with NIFTY IT closing in the green (+0.30%) even as the benchmark indices fell over 1%. The stock saw heavy participation at 1.74 crore shares, indicating aggressive rotation into large-cap IT amid sharp selling in cyclicals like autos.

Siemens Energy India Ltd (+3.88%) Siemens Energy India advanced as investors preferred grid and power infrastructure-linked plays, which showed relative resilience versus the sharp fall in NIFTY AUTO (-4.07%) and NIFTY METAL (-2.64%). The counter also saw high activity with 17.53 lakh shares traded, supporting the upmove.

HDFC Life Insurance Company Ltd (+2.54%) HDFC Life rose as investors sought comparatively defensive financials during a session marked by weak breadth and index declines. The stock’s gain came alongside strong trading volumes of 41.80 lakh shares, highlighting demand even as the broader finance pack stayed under pressure.

Hitachi Energy India Ltd (+2.30%) Hitachi Energy India gained in tandem with strength in power equipment names, as investors positioned for execution visibility in the grid and transmission ecosystem. The stock added ₹700 per share, with 1.53 lakh shares traded on the day.

Cummins India Ltd (+2.18%) Cummins India moved higher as investors rotated into industrials showing relative strength against a broader sell-off, with NIFTY IT holding up while several cyclical indices dropped sharply. The counter traded 4.11 lakh shares, supporting the day’s rise.

Mid Cap Top Gainers

IDBI Bank Ltd (+5.56%) IDBI Bank rallied on unusually heavy trading activity, with volume at 2.90 crore shares, making it one of the most actively traded mid-cap gainers. In a weak session for broader indices, the sharp move appeared driven by momentum positioning and churn among high-volume banking names.

Sterlite Technologies Ltd (+5.00%) Sterlite Technologies jumped to ₹954.30, matching its 52-week high, which typically triggers momentum buying as breakouts attract incremental traders. The move was accompanied by strong volume of 58.62 lakh shares, reinforcing the breakout-style rally.

Mphasis Ltd (+4.45%) Mphasis climbed as IT counters outperformed the market, consistent with NIFTY IT ending higher while benchmarks closed sharply lower. Volumes stood at 12.31 lakh shares, indicating broad participation in the mid-cap IT upmove.

Coforge Ltd (+4.18%) Coforge gained in line with the day’s relative strength in IT, as investors sought earnings defensiveness and export-heavy business models during a risk-off tape. The stock was actively traded with 35.71 lakh shares changing hands.

Indo-MIM Ltd (+2.56%) Indo-MIM rose as investors selectively accumulated industrial names that held up better than the broader mid-cap index, which fell 1.79% per the market context. The counter traded 13.14 lakh shares and remained within reach of its 52-week high of ₹1,355.90, supporting the move.

Small Cap Top Gainers

Molbio Diagnostics Ltd (+15.32%) Molbio Diagnostics surged after a bulk deal-led change in shareholding, with the market tracking HDFC Mutual Fund’s purchase of a 1.99% stake, as per the web context. The rally was also supported by Street interest after Jefferies initiated coverage with a ‘Buy’ rating and a ₹1,600 target, and the stock traded massive volume of 1.01 crore shares.

Thomas Scott India Ltd (+12.72%) Thomas Scott India jumped after the company disclosed voting results and the scrutinizer’s report for its 16th AGM held on 29 Sep 2026, where all resolutions were passed, including adoption of financials and reappointment of the director and MD. Investors typically read such outcomes as removal of decision overhangs, especially when related-party transaction approvals are cleared, supporting the sharp price reaction.

Hero Motors Ltd (+9.99%) Hero Motors rose to ₹167.80, its 52-week high, as post-listing momentum continued in the counter, supported by very heavy volume of 9.78 crore shares. The market also tracked AGM-related developments, including shareholders adopting the audited FY26 financial statements, per the web context.

Viviana Power Tech Ltd (+9.96%) Viviana Power Tech rallied as the market continued to price in order-flow expectations after the company emerged as L1 bidder for a ₹139.49 crore PGVCL project to convert overhead lines into underground cabling in parts of Rajkot, as per the web context. The stock’s sharp move came despite relatively low reported volume of 1.40 lakh shares, indicating a tight supply response.

Augmont Enterprises Ltd (+9.86%) Augmont Enterprises climbed close to its 52-week high of ₹1,205.05, ending at ₹1,203.55, a setup that often draws breakout-led buying in newly tracked names. The move was backed by active trading of 29.12 lakh shares, highlighting strong participation on the day.

Market Overview

Indian equities closed sharply lower on 01 Oct 2026, with Nifty 50 settling at 22,335.35 (-1.26%) and the Sensex at 71,669.31 (-1.12%), as broad-based selling pulled down large, mid and small-cap indices. Market breadth remained extremely weak, with only 48 advances against 452 declines in the BSE500, underscoring that gains were concentrated in a handful of counters.

Sector performance showed clear divergence. NIFTY IT ended higher (+0.30%), aligning with gains in Infosys, Mphasis and Coforge, while NIFTY AUTO slumped 4.07% and NIFTY METAL fell 2.64%, consistent with the session’s de-risking in cyclicals. Financials were mixed, with BANKNIFTY down 0.46% and NIFTYFINANCE down 0.58%, but select defensive financial names like HDFC Life still managed to finish among the gainers.

Macro and flow cues in the market context pointed to elevated crude prices and continued caution from foreign investors, keeping risk appetite constrained even as pockets such as IT and select power infrastructure-linked names showed resilience.
