Mumbai: The BSE benchmark Sensex on October 26 fell by over 75 points in opening trade due to profit-booking at higher levels amid a weakening trend on other Asian bourses.

The 30-share index, which had gained 48.61 points on October 25, fell by 75.07 points, or 0.40 percent, to 18,683.56, with stocks of oil and gas, IT and banking sectors succumbing to profit-booking.

Similarly, the wide-based National Stock Exchange Nifty Index moved down by 23.20 points, or 0.40 percent, to 5,682.10.

Brokers said apart from profit-booking by investors after October 25 gains, a weak trend in the Asian region ahead of U.S. economic growth figures to be released later in the day, mainly led to a fall in stock prices.

Meanwhile in the Asian region, Japan’s Nikkei was down by 0.89 percent, while Hong Kong’s Hang Seng index shed 0.79 percent.

The U.S. Dow Jones Industrial Average ended 0.20 percent higher on October 25 trade.
