Why These Stocks Are Rising and Falling Today: Pine Labs, Physicswallah & Sun TV Gain; Cochin Shipyard, Godrej Properties & Lodha Developers Decline

The Indian benchmark indices declined on Friday as rising geopolitical tensions in West Asia pushed crude oil prices higher. The increase in oil prices raised concerns over inflation and added pressure on investor sentiment.

The Nifty 50 and Sensex slipped to their lowest levels since June, with selling pressure visible across sectors. Mid- and small-cap stocks were also affected by the broader market weakness. Meanwhile, Brent crude rose above $108 per barrel in Asian trading and was approaching the $110 mark.

Amid the market-wide volatility, several stocks witnessed sharp movements. Here are the top Nifty 500 gainers and losers of the day.
