The Sensex at the Bombay Stock Exchange jumped 180 points, to 16,588 in early trade today. Remaining firm, the Sensex stood 155 points, or 1 per cent in the green, at 16,564, a short while ago. The market was lifted by a solid rally in oil major, ONGC. Shares of ONGC surged over 8 per cent, and Oil India jumped over 7 per cent, after the government on Wednesday more than doubled the price of natural gas to cut the losses suffered by oil companies. But other Asian bourses in Japan, China, Indonesia, Singapore, Hong Kong, South Korea and Taiwan were down between 0.8 per cent and 2.3 per cent, as worries about the Eurozone continued to mar investors' appetite for risk.
