Led by a smart rise in the top heavyweight RIL amid sustained FII inflows, the benchmark sensex continued its rally for the straight second session and improved further by over 139 points to close at nearly seven month high of 18,428.61, despite narrowly mixed global trends. The Bombay Stock Exchange 30-share gauge resumed better and remained in a positive terrain throughout the day before concluding at 18,428.61, highest closing since July 27, 2011, showing a net rise of 139.26 points or 0.76 per cent. Last Friday, it had gained by 135.36 points or 0.75 per cent.
