Wockhardt, Tata Technologies, CAMS Lead Top Gainers; JP Power, CESC, Aarti Industries Among Top Losers

The Indian equity markets were trading with downward bias on May 5, 2026, due to escalating geopolitical risks in the Middle East, which sent crude oil prices up, thus affecting the investment mood. The indices such as the Nifty 50 and the Sensex were trading down initially along with the Indian rupee that registered its record low level. The Brent crude was trading above the $115 mark due to fears regarding supply shortages, which increased the inflationary pressures for India, which is a significant importer of crude oil.

Even in the adverse market condition, some stocks from the Nifty 500 list showed a surge, primarily due to their earnings and other factors, whereas many stocks were down sharply.

Top Gainers: Wockhardt, Tata Technologies, CAMS

Wockhardt: Strong Earnings Turnaround Drives 13% Surge

Wockhardt, which is a pharmaceutical company specializing in the production and distribution of formulations and active pharmaceutical ingredients, came out on top as one of the biggest winners of the day. Its share price gained 13%, buoyed by strong trading volumes, as 1.12 crore shares were traded compared to the company’s 30-day average volume of 7.08 lakh shares.

Its stock rally was mainly fueled by a massive turnaround in its Q4FY26 financial results. It posted a 30% increase in revenues from a year ago to ₹965 crore, along with a 147% rise in EBITDA to ₹196 crore, resulting in margins expanding to 20.3%. Most importantly, it recorded net earnings of ₹164 crore, against net losses of ₹45 crore recorded in the same period a year ago. For the entire fiscal year 2026, it posted an 11% increase in revenues, a 51% increase in EBITDA, and recorded net earnings of ₹199 crore.

Tata Technologies: Earnings Recovery and Dividend Announcement Fuel Gains

Tata Technologies, which is a digital engineering and product development company catering mostly to automotive and industrial customers, saw a surge in its price, with gains of about 10-12% during the day. The trading volumes were also healthy, with total volume of trade being 2.04 crores against the 30-day average of 11.44 lakhs.

This gain came on the back of improved performance in the fourth quarter of fiscal year 26. There was a 15% increase in revenues to ₹1,572 crores, along with growth in the services business of 15% to ₹1,220 crores. There was also an increase of 31% in EBITDA to ₹252 crores, with margin increasing 190 bps to 16%. Profit was up by 20% to ₹163 crores.

Apart from this, there was also a dividend of ₹11.7 per share declared, adding to the already good news for investors.

CAMS: Strong AUM Growth and Market Leadership Support Stock

CAMS (Computer Age Management Services), India's top registrar and transfer agent for mutual funds and other financial institutions, was up by about 8% with the strength of trading volume in the region of 51.24 lakh against a 30-day average of 14.4 lakh shares.

The company's results were buoyed by robust growth in the asset under management (AUM), which stood at ₹55.1 lakh crore as of March 31, 2026, marking a 21% rise from the previous year. CAMS' market share continued to be dominant at 68%, with AUM in the equity segment standing at ₹30.5 lakh crore.

From an operational perspective, the company achieved record quarterly revenues of ₹395 crore, registering an increase of 11% YoY. In addition, net profit for the period showed a similar increase of 11% to ₹126 crore. Robust systematized investment plan (SIP) inflows also contributed, rising by 46% YoY.

Top Losers: JP Power, CESC, Aarti Industries Decline 

While certain stocks performed positively, there were other stocks that saw a downtrend amid the market’s prevailing risk-off tone amid the rise in crude oil prices and geopolitical risks.

JP Power: Sharp Decline Amid Market Weakness

JP Power, a company involved in power production and infrastructure creation, saw a steep fall of more than 6%. The share price dropped from the previous closing price of ₹19.06 to ₹17.90, with volume crossing the 8.23 crore mark.

There were no apparent reasons for this fall in the form of any adverse events at the firm. It seems that this drop is mainly due to weakness in the overall market coupled with selling in stocks of power and infrastructure firms.

CESC: Profit Booking and Sectoral Pressure Weigh on Stock

CESC Ltd, which engages in power production and distribution and operates mainly in Kolkata, fell by 5.7% from ₹198.72 to ₹187.33. There was heavy buying and selling of CESC stocks, with 48.37 lakh shares being traded in the market.

The fall in CESC shares is largely because of the weakness in power stocks generally and the fact that profits have been made from previous gains. Also, the risk-off tendency because of macroeconomic risks and crude prices may have led to selling.

Aarti Industries: Falls Despite Strong Earnings, Reflects Market Pressure

The specialty chemicals maker for the international pharmaceuticals, agrochemicals, and polymers industries, Aarti Industries, fell nearly 5.7%, with the share price falling from ₹513.10 to ₹483.90.

Interestingly, the company had announced impressive quarterly figures for the quarter ended March 2026, with net profit growing by 42.7% and sales up by 13.2%. Nonetheless, despite the fundamentals being positive, the stock fell, implying that overall market sentiments and profit-taking played a significant role compared to the earnings optimism.

Conclusion

May 5 trading session presents an interesting case study that demonstrates how the market had two contrasting forces at play. While some of the stocks moved up because of their fundamentals like earnings and growth outlook in stocks like Wockhardt, Tata Technologies, and CAMS, many others fell because of broader macroeconomic issues like increasing oil prices and geopolitical instability affecting stocks like JP Power, CESC, and Aarti Industries.

However, despite the indices coming under pressure, the earnings-induced movement in select mid and small cap stocks clearly indicates that there are still opportunities available for investors in fundamentally robust stocks.
