The BSE benchmark Sensex regained the crucial 19,000-level in early trade today, adding 287 points on fund-based buying driven by a firming global trend. The 30-share index of the Bombay Stock Exchange surged to 19,087 point in opening trade. It had risen by nearly 133 points in the previous session. The buoyant investor sentiment also propelled the wide-based National Stock Exchange Nifty past the 5,700-mark. The Nifty gained 83.60 points to 5723 point. Both indices have regained these levels after almost 32 months.
