Top Gainers: Cohance Lifesciences, Piramal Finance, Chennai Petroleum Lead Rally; Top Losers: Can Fin Homes, Eternal, Zydus Lifesciences Drag

Cohance Lifesciences Share Price Surges 16% on Leadership Boost and Strong Momentum

One such CDMO in the pharmaceutical industry was Cohance Lifesciences, which was the biggest gainer among other gainers, with its share price rising by 16% on April 28. This has come along with a substantial spike in the volume, which went up from an average 30-day figure of 37.40 lakh to 2.22 crore.

The primary reason for the rise has been the decision to appoint the former CEO of Cipla, Umang Vohra, as the company's Executive Chairman and Group CEO. It is believed that such decisions have helped restore investor faith in the company, thus leading to market expectations of a turnaround and revival in growth.

Apart from this, the shares have also seen accumulation and technical breakouts, helping to fuel the rally. However, even after rising by over 35% in just two days, the shares continue to fall 56% below last year's levels due to poor performance and stagnant growth.

Piramal Finance Share Price Gains 12% on Robust Q4 Earnings

Another non-banking financial company (NBFC) that offered financial lending services also made it to the list of major winners, having gained 12% in its stock price during the day. Its stock showed robust trading volume, recording 37.88 lakh stocks being exchanged on the floor compared to the average volume of 3.86 lakh stocks for the last 30 days.

The company saw a strong surge on account of solid Q4FY26 earnings. The asset under management grew by 25%, reaching the figure of ₹1 lakh crore. Net interest income soared 41% to ₹1,362 crore, while margins improved slightly. Gross NPAs were steady at 2.3%, while net NPAs stood at 1.6%.

However, the key driver of the strong earnings report was the company's massive profits increase of 390% to ₹502 crore, but still, on a very low base.

Chennai Petroleum Share Price Rises 7% on Strong Refining Margins

Chennai Petroleum, a government-owned oil refinery company, witnessed its share prices rise by 7%. Its stock saw a modest rise in volumes, where it traded higher than its 30-day moving average volume.

The stock’s move was mainly due to its excellent Q4FY26 results. Although there wasn’t much change in revenues that stood at ₹20,455 crore, its profits jumped over 300% to ₹1,400 crore from ₹450 crore last year during the same period. This was mainly because of a significant increase in gross refining margins (GRM) that rose by nearly 120% to $13.75 per barrel from $6.22 per barrel.

Furthermore, it declared dividends worth ₹62 per share, out of which the final dividend was ₹54 and interim was ₹8.

Top Losers: Can Fin Homes, Eternal, and Zydus Lifesciences Decline Amid Weak Sentiment

Although certain equities rose in value, there were some Nifty 500 stocks that experienced declines owing to profit-taking and lack of triggers.

Can Fin Homes is a housing finance firm that primarily offers services related to home loans, and it fell 3.72% to close at ₹134.53. The equity experienced moderate volumes, totaling 12.05 lakh shares. In view of the absence of any trigger from Can Fin Homes itself, the decline could have been market-driven and possibly profit-taking.

Eternal, which has a business presence in the particular line of activities (probably a mid-cap diversified/sector-specific holding), declined 3.28% to ₹247.10. The equity traded heavily, with total volumes of 2.86 crore shares being seen. Since there has not been any news trigger for Eternal's decline, one may conclude that selling pressure led to the price fall.

Zydus Lifesciences is one of the leading pharmaceutical firms that manufacture generic drugs, and it closed down 3.26% at ₹909.05. The volume of transactions in Zydus Lifesciences was comparatively lower, totaling 9.3 lakh shares. No news trigger for the particular equity was noted.

Conclusion

The session showed notable company-wise activity against the backdrop of the overall market environment. Cohance Lifesciences was the top gainer following a key leadership shift and good investor sentiment, whereas Piramal Finance and Chennai Petroleum were among the gainers owing to their strong financial performance.

Conversely, Can Fin Homes, Eternal, and Zydus Lifesciences were among the losers, owing to the absence of catalysts and profits booking. In all, the strong volume of transactions played a critical role in influencing the movement of prices, suggesting that investor interest continues despite global tensions and higher crude oil prices.
