The benchmark BSE Sensex extended yesterday's losses by declining over 54 points in early trade today as funds and investors indulged in trimming positions, tracking a weak trend overseas.

However, shares of companies related to railways were in keen demand after the government yesterday approved FDI liberalisation in the sector. The 30-share barometer, which had lost 242.74 points in the previous session, fell by 54.13 points, or 0.21 per cent, to 25,611.14 in early trade.

On similar lines, the broad-based National Stock Exchange index Nifty shed 13.30 points, or 0.17 per cent, to 7,658.75.
