Recovering swiftly from early losses, the Sensex at the Bombay Stock Exchange stood a solid 246 points, or 1.4 percent in the positive zone, at 18,486 in afternoon deals, a short while ago. Public sector oil marketing companies jumped after the government's move to hike prices of petro-producs. Earlier in the morning, however, the Sensex had declined 29 points, to 18,212, within the first few minutes of trade. But other Asian bourses in Japan, Hong Kong, Indonesia, Singapore, South Korea, and Singapore were down by between 0.5 per cent and 1 per cent, after regulators raised capital adequacy requirements for the world's biggest lenders, amid concern that the US economy is faltering.
