Nifty closed above 25,000 for the first time since July, setting the stage for a key weekly expiry. Analysts say sustaining above the 50-DMA at 25,000 could open upside towards 25,250-25,350, with supports at 24,800-24,850. Momentum looks positive with EMAs turning supportive, but traders caution a dip or retest is possible before further gains.
