Summary:
Indian markets ended lower amid global uncertainty and rising geopolitical tensions linked to the Iran issue.Among the top gainers today, PCBL, GE Vernova and BLS International rallied sharply on strong buying interest and earnings momentum. Meanwhile, PI Industries and ZEEL emerged among the top losers after weak quarterly performance weighed on investor sentiment.
The Indian equity indices closed down on May 20 due to negative sentiments abroad and growing geopolitical tensions arising from the Iran issue. The Sensex fell 0.6% to close at 74,733, and the Nifty 50 lost 0.5% to close at 23,487. Higher global interest rates and negative performance from other markets dampened investor sentiment.
Despite the fall in the overall market, many Nifty 500 stocks saw big movements on account of earnings, volume, and individual company activity.
PCBL, one of the world’s largest carbon black manufacturers, surged 10% with strong trading activity. Volume on the NSE jumped to 83.9 lakh shares against the 30-day average of 14.62 lakh shares.
There was no immediate trigger for the rally, and the move appeared to be largely driven by market forces and buying interest after recent corrections. Earlier, the company had reported weak Q4FY26 earnings.
Revenue remained nearly flat at ₹2,066 crore compared to ₹2,087 crore a year ago. EBITDA declined 22% to ₹248 crore, while net profit fell 60% to ₹40 crore due to trade war disruptions and higher supply chain costs. However, the company maintained a positive FY27 outlook focused on specialty products and cost optimisation.
GE Vernova T&D India, which operates in the power transmission and distribution segment, was among the top gainers after reporting strong Q4FY26 earnings.
The stock rose 10%, while trading volume increased to 12 lakh shares compared to the 30-day average of 7.15 lakh shares.
Revenue rose to ₹1,637 crore from ₹1,153 crore in the year-ago quarter, driven by strong execution of orders. EBITDA jumped 76.5% to ₹445 crore, while profit before tax increased to ₹469 crore from ₹256 crore last year.
The company’s order book also expanded sharply to ₹21,460 crore as of March 2026, boosting investor confidence.
BLS International Services, a visa processing and consular services provider, climbed 10% after strong Q4FY26 earnings. Trading volume surged to 2.03 crore shares against the 30-day average of 30.4 lakh shares.
Revenue increased 18% year-on-year to ₹815 crore, while EBITDA rose 17% to ₹204 crore. Net profit jumped 29% to ₹187 crore despite geopolitical challenges impacting global travel demand.
The company also reported strong FY26 growth, with revenue rising 37% and net profit increasing nearly 34%.
Agrochemicals and custom chemicals maker PI Industries plunged by nearly 7% after posting dismal fourth quarter results for FY26. The fall in profit was triggered by poor export performance, correction in inventories worldwide, and lower margins in the agrochemical segment.
Zee Entertainment Enterprises (ZEEL), which is one of India’s top media and broadcasting firms, slumped by over 6% after posting a net loss in the quarter due to low advertising spend and increased costs.
The parent company of MapmyIndia, CE Info Systems, too closed on a negative note. The firm offers solutions in digital mapping and navigation. There was no apparent reason for this fall in price, and it seemed that the slide was fueled primarily by poor market sentiments.
Though the overall market was under pressure due to global uncertainties, stocks such as GE Vernova and BLS International were up sharply on good results and heavy volumes. PCBL was also up sharply despite poor results, while poor results pulled down PI Industries and ZEEL.
