After its record fall yesterday, the Sensex opened strong on Tuesday morning (August 25) and soared 383 points within minutes but a sharp bout of volatility soon engulfed the markets in the morning trade. In a see-saw trade, the index slipped into the negative territory but recovered and was up 120 points at 25,862 points at 0945 hrs. At the same time, the Nifty of the National Stock Exchange rose by 38.60 points to 7,847.60 after dipping to a low of 7,801 in early trade. The Sensex had opened strong by 383 points and the Nifty recaptured 7,900 level in early trade on across the sector value-buying by participants even as Chinese markets continued to slide. All the sectoral indices led by realty, metal and consumer durable led the recovery. Brokers said emergence of buying at prevailing lower levels in bluechips coupled with covering-up of short positions by speculators, helped key indices to trade in the positive zone.
