Equity benchmark Sensex crossed the 57,000-mark for the very first time, as it jumped over 200 points in early trade on Tuesday, tracking gains in index heavyweights Infosys, HDFC Bank and TCS amid fresh foreign fund inflows. In tandem, the broader NSE Nifty was trading a tad below the crucial 17,000-mark. After touching a lifetime high of 57,124.78 in the opening session, the 30-share index was trading 115.53 points or 0.20 per cent higher at 57,005.29. Similarly, the broader NSE Nifty advanced 24.15 points or 0.14 per cent to 16,955.20.

Bharti Airtel was the top gainer in the Sensex pack, rising over 1 per cent, followed by HCL Tech, Tech Mahindra, TCS and Asian Paints. On the other hand, M&M, IndusInd Bank, SBI and Reliance Industries were among the laggards. In the previous session, the BSE index ended 765.04 points or 1.36 per cent higher to 56,889.76, and Nifty surged 225.85 points or 1.35 per cent to its record closing of 16,931.05.
