Nifty rebounded from the 24,900-25,000 support zone, holding above key levels like the 50-DMA (25,039) and 61.8% Fibonacci (24,923). Analysts say a breakout above 25,100-25,205 could confirm bullish momentum. Resistance lies at 25,325-25,415, while support holds at 24,900. Volume remains subdued, so Tuesday's session may decide if bulls can sustain the rebound.
