The Sensex at the Bombay Stock Exchange, which had gained 175 points in early trade, today, later eased somewhat, but still stood 143 points, or 0.7 percent in the green, at 20,489, a short while ago. Good second quarter domestic corporate results, expectations that the Reserve Bank's rate hike will not have much impact on economic growth, and positive global cues helped boost investor sentiment. Other Asian bourses in China, Singapore, Hong Kong and South Korea were up by between 0.1 percent and 2 percent, today, as investors awaited the outcome of the two-day US central bank meeting. In the US, the key Dow Jones Industrial Index had added 0.6 per cent, overnight.
