Later, in afternoon trade, the Sensex gave up some of its initial gains, but still stood 106 points, or 0.6 per cent in the green, at 16,825, a short while ago. The Sensex has already rallied 754 points in the previous five trading sessions. Stock markets in Japan, China, Hong Kong, South Korea, Taiwan, Indonesia and Singapore had gained between 0.8 percent and 2.4 percent, today, after finance ministers of the euro-zone nations, last week, agreed to lend Spain up to 100 billion euros to stabilise its banks.
