India's benchmark Nifty 50 index closed 0.4% higher at 25,103.20 on Monday, rising over 150 points in early trade but losing momentum as the market drifted into a narrow range around the 25,100 mark. SEBI-registered analyst Mayank Singh Chandel said the index opened strong but failed to sustain early gains, forming a small-bodied candle with wicks on both ends.
