The B S E benchmark Sensex fell by over 46 points in the opening trade on Tuesday, on profit-booking amid weak trend on the other Asian markets.

The 30-share barometer, which had gained 14.38 points in Monday’s session, moved down by 46.68 points or 0.23 per cent to 19,934.63 points, with a decline in banking, realty and auto sector stocks.

Similarly, the wide-based National Stock Exchange index Nifty declined by 13.40 points or 0.22 per cent to 5,978.85 points.

Brokers said profit-booking in select heavy-weight stocks coupled with weak Asian bourses following overnight losses at the US markets, weighed on the trading sentiment in Mumbai.

Besides, banking stocks were also subdued following rise in deposit rates, which put pressure on their interest margins.

In other markets in Asia, Hong Kong’s Hang Seng index was trading lower by 0.31 per cent, while Japan’s Nikkei shed 0.14 per cent in early trade on Tuesday.

In the US, Dow Jones Industrial Average ended 0.17 per cent low at Monday’s close.
