Indian equities were trading firm at noon, with the Nifty, Sensex and Bank Nifty all in the green. Despite the broader strength, a handful of heavyweight Nifty 50 stocks were under pressure in midday trades, led by healthcare, power utilities and FMCG names. At around 12:00 PM IST, the Nifty 50 was trading higher by 0.56%, while the Sensex and Bank Nifty were also firmly in the green.

Max Healthcare Institute emerged as the top loser among the Nifty 50 constituents, slipping 1.6% to ₹1,022.8. The stock saw selling pressure during the session, making it the weakest performer in the index at midday.

Power Grid Corporation was down 1.3%, trading at ₹288.9. The decline came despite strength in the broader PSU and infrastructure space.

ITC traded 0.9% lower at ₹322.9. The stock continued to face pressure in intraday trade, keeping it among the laggards in the benchmark index.

ICICI Bank slipped 0.7% to ₹1,396.6. The banking major underperformed the Bank Nifty, which was otherwise showing strong gains during the session.

Oil and Natural Gas Corporation was marginally lower by 0.5%, trading at ₹267.6, even as energy stocks showed mixed movement across the market.

Nestlé India declined 0.5% to ₹1,297.2, remaining under mild selling pressure in midday deals.

NTPC was down 0.3%, trading at ₹363.9, despite continued strength in the broader power sector.

Infosys slipped 0.3% to ₹1,502.6, as IT stocks showed subdued movement during the session.

Bajaj Finance edged lower by 0.2%, trading at ₹979.3, reflecting marginal profit-booking.

HDFC Bank also traded 0.2% lower at ₹939.0, underperforming the broader banking index.

Overall, while headline indices remained comfortably higher at midday, these stocks stood out as the key drags within the Nifty 50, reflecting selective selling rather than broad-based weakness in the market.
