Mumbai: Driven by continued selling by funds amid losses in other Asian bourses, Bombay Stock Exchange benchmark Sensex dropped 74 points in opening trade at 19,017.16 level on Tuesday.

The BSE 30-share index, which has lost over 600 points in the previous two sessions, opened 74.01 points lower with realty, auto, metals and oil and gas sector stocks leading the fall.

Similarly, wide-based National Stock Exchange index Nifty lost 19.90 points, or 0.35 per cent to 5,709.20 points.

Brokers said trading sentiment turned bearish on funds' selling, triggered by weakening trend on other Asian bourses in line with overnight losses in the US as the rating agency
Standard and Poor's cut its credit outlook to negative.
