Nifty dipped to 25,495 amid US-India trade talks, with analysts warning of bearish momentum if it breaks 25,460. Analyst Kush Ghodasara called it a cliff edge and advised a stop-loss at day low. Ashish Kyal said a 15-minute close below 25,460 could trigger a fall to 25,380. Traders are urged to stay cautious as the trend remains uncertain.
