The positive momentum reflected improved investor sentiment, although the green energy sector witnessed mixed stock-specific movements.

Among renewable and clean energy-related companies, Kabra Extrusion emerged as the biggest gainer of the day, rallying 7.9%. The sharp rise made it the standout performer in the sector as investors showed strong buying interest.

Wind turbine manufacturer Inox Wind also traded higher, gaining more than 1.6% to close at ₹78.21 on both exchanges. Other major companies in the green energy ecosystem also finished in positive territory. Tata Power added 0.85%, while engineering major Larsen & Toubro (L&T) rose 0.43%. Reliance Industries and Borosil Renewables posted marginal gains, reflecting stable investor confidence despite limited price movement.

On the other hand, several renewable energy and battery-related stocks ended the day in the red. Exide Industries was among the biggest losers, falling 3.28% on the BSE to ₹428.40 and declining 3.81% on the NSE to ₹426.10.

Meanwhile, Amara Raja Energy & Mobility and Insolation Energy remained largely unchanged, indicating cautious investor participation.

Overall, while the benchmark indices ended with strong gains, the green energy sector presented a mixed picture. Investors continued to focus on company-specific developments, resulting in varied performances across renewable energy, battery manufacturing, and clean technology stocks.
