Domestic stock markets started Wednesday's session on a subdued note tracking a weak trend in Asian peers. However, the benchmarks reversed the weak trend on the back of buying in Reliance Industries, HDFC Bank, IndusInd Bank and Axis Bank. However, the gains were capped as HDFC, Tata Consultancy Services, Vedanta and ONGC were witnessing selling pressure. The S&P BSE Sensex benchmark index rose as much as 91.99 points in early deals to 39,908.47 and the NSE Nifty index moved to 11,932.15, up 21.85 points from the previous close.
