Mumbai:  The BSE benchmark index Sensex extended losses for the second straight day by losing over 67 points in early trade on Monday on sustained selling by funds, triggered by a weak trend on Asian bourses.
The 30-share index, which had lost 238.11 points in the previous session, fell further by 67.19 points, or 0.39 percent, to 17.027.32, as Refinery, Metal, Auto and IT sector stocks led the fall.
The wide-based National Stock Exchange index Nifty declined by 18.25 points, or 0.35 percent, to 5189.20.
Brokers said sustained selling by funds in tandem with a weak trend on other Asian bourses, following renewed concerns about the euro zone's sovereign debt crisis, mainly influenced the trading sentiment here.
In the Asian region, the Hong Kong's Hang Seng index fell by 0.81 percent, while Japan's Nikkei index was down by 1.45 percent in early trade on Monday. The US Dow Jones Industrial Average ended 1.05 percent lower in the previous session.
