Firstsource Solutions, Thermax and MRPL Lead Top Gainers While Dalmia Bharat, CCL Products and ACME Solar Drag

Indian stock market benchmark indices traded lower during Friday trade, as the increase in crude oil prices, negative foreign institutional investments, and weak global cues weighed down sentiments among investors. Tensions rising in West Asia also put downward pressure on the indices.

The Sensex was lower by 427.87 points or 0.55 percent to settle at 77,416.66 while the Nifty slipped by 119.60 points or 0.49 percent to close at 24,207.05. Majority of the sector indices were trading on the downside, though FMCG, IT, and pharma shares proved resilient. The small-cap Nifty Smallcap100 Index and mid-cap Nifty Midcap100 Index made positive gains.

However, despite negative sentiments prevailing in the market, there were instances of sharp movements among stocks within the Nifty 500 Index.

Firstsource Solutions Share Price Surges 16%

Among the top gainers for Nifty 500 on May 8, was Firstsource Solutions. The stock had surged by close to 16 percent. The company is a BPM leader and is associated with the RP-Sanjiv Goenka Group.

On the NSE, the trading volume had spiked to 584.51 lakh shares, which was much higher when compared to the 30-day average of 70.8 lakh shares.

The steep spike in prices followed the announcement of record performance in FY26, with revenue and EBIT margins expanding. This was attributed to successful wins in new deals and clients, apart from artificial intelligence transformation projects being carried out.

The company had further guided for growth rates in the range of 10-13 percent constant currency growth in FY27, with increased EBIT margins.

Thermax Share Price Jumps 12% After Q4 Beat

Thermax Limited is another significant winner following its better-than-expected March quarter performance.

Its share price appreciated almost 12 percent, recording its largest gains in almost four years. Trading volume soared to 20.50 lakh stocks on the NSE versus an average of 2.90 lakh stocks during the past 30 days.

Thermax registered a 19 percent year-on-year growth in net profit to ₹244.3 crore while revenues jumped 12.5 percent to ₹3,428 crore. Its EBITDA jumped 24.9 percent to ₹374.3 crore, with its EBITDA margin expanding to 10.9 percent compared to 9.8 percent last year.

The company has proposed a final dividend of ₹14 per stock for FY26.

Thermax informed that strong order inflow was on account of high demand in its industrial products and industrial infrastructure categories. In addition, it saw healthy contributions from heating, cooling, and water/waste management categories. For the quarter, the company bagged orders for a boiler package worth ₹1,600 crore, enhancing visibility of growth.

On the downside, the chemicals business was facing issues due to rising input prices and change in product mix, while green solutions margins were hurt by project overruns.

MRPL Share Price Climbs 7% On JV Development

The stocks of Mangalore Refinery and Petrochemicals Limited (MRPL) appreciated by around 7 percent and also formed a part of the top gainers in the Nifty 500 stock indices. The company is owned by ONGC and is into oil refining and petrochemical business.

The trading volume increased sharply to 451.69 lac stocks from the 30-day average of 108.9 lac stocks.

This sharp appreciation happened on account of the news of the approval of the creation of the joint venture between MRPL and OPaL in a shareholding pattern of 50:25:25 with the objective of integrating petrochemical marketing activities.

MRPL has decided to make investments worth ₹12.5 crore in the JV subject to DIPAM clearance.

The market welcomed the move as it would result in cost efficiencies and synergies.

Dalmia Bharat Shares Fall Nearly 7%

Another stock which fell heavily was Dalmia Bharat Limited, which came under the list of major losers within the Nifty 500 index, dropping by 6.69 percent. It is one of India's leading cement producers.

The fall seems to have been triggered by the negative market sentiments as well as profit-taking by investors in the face of potential margin problems in the cement industry.

CCL Products Shares Drop Over 6%

Moreover, shares of CCL Products (India) Limited slipped by 6.69 percent. CCL Products (India) Limited is a major producer and exporter of instant coffee.

The share price continued to fall because of worries over rising expenses, fluctuations in margins, and high debts even though there has been steady growth in its revenues.

ACME Solar Shares Slip More Than 5%

ACME Solar Holdings Limited fell by 5.38 percent and was one of the biggest losers in the Nifty 500 index. The firm is engaged in the renewable energy industry.

There was no apparent reason for the fall that emerged from any particular event associated with the company. It seems that the fall was caused mainly due to market conditions.

Conclusion

Nifty 500 Stocks with robust fundamentals, company-related news, and high volume trades witnessed positive momentum. Firstsource Solutions rallied due to stellar FY26 results along with favorable outlooks, while Thermax jumped after beating its Q4 earnings estimates. MRPL rallied due to ONGC approving a joint venture for petrochemical marketing with MRPL and OPaL.

In contrast, Dalmia Bharat, CCL Products, and ACME Solar continued to witness selling pressures amid sector-specific factors, margin issues, and broad market selling trends.
