The domestic markets posted strong gains for the second day in a row, thanks to the sharp up-move in automobile and technology stocks. The sentiment was bolstered as the S&P500 index of the US jumped 2 per cent overnight, its biggest-single day surge since June. Though some Asian markets pared gains after China’s top banking regulator raised concerns over asset bubbles, the Indian markets outperformed. The Sensex added 0.9 per cent, or 447 points, to end at 50,297, while the Nifty50 rose 1.1 per cent, or 158 points, to finish at 14,919. On the other hand, Wall Street's major averages dipped after a strong start to March as investors closely monitored the bond market, as well as progress on the next round of fiscal stimulus.
