Top Gainers and Losers on December 8, 2025: Tech Mahindra and Kaynes Technology in Focus

The Nifty 50 closed at 25,960.55 on December 8, down 225.90 points or 0.86% from the previous session. The index witnessed broad-based selling across sectors, with aviation, defence and high-valuation stocks under pressure.

IT and select financial counters managed to stay resilient despite overall weakness. Trading activity remained elevated, driven by substantial volumes in technology, aviation and defence stocks.

Market Overview

Indian markets have responded positively to the Reserve Bank of India’s recent 25 bps rate cut, which came despite strong Q2 GDP data. The move, combined with lower inflation forecasts and liquidity measures, has triggered a risk-on sentiment across equities.

Rate-sensitive sectors such as autos, real estate and NBFCs have led gains in recent sessions. However, profit-booking emerged today in several heavyweight counters, pulling the Nifty 50 lower.

Weakness in Aviation and Defence Stocks Dragged the Index

Aviation stocks such as IndiGo recorded sharp declines, falling 8.62% during the session. Defence companies including BDL and Mazagon Dock also witnessed notable sell-offs with losses of 5.98% and 5.09%, respectively.

These segments faced heavy trading volumes, indicating concentrated pressure from market participants. The combined weakness in aviation and defence contributed significantly to the overall downturn in the market.

Conclusion

The Nifty 50 ended lower by 0.86% on December 8, with sharp declines in aviation, defence and select high-valuation stocks. Technology and financial counters provided limited support, led by gains in Tech Mahindra and Policybazaar.

Heavy selling in Kaynes Technology and IndiGo contributed significantly to the index’s fall. Market participants continued to monitor sector trends following the RBI’s recent rate cut and its impact on rate-sensitive segments.
