The BSE benchmark Sensex today lost over 79 points in early trade as stocks of FMCG, metal, auto, healthcare and banking sectors fell on sustained capital outflows, tracking a weak trend in the global market. 

Extending losses for the second session, the 30-share index fell by 79.13 points, or 0.42 per cent, to 18,640.162. The index had lost 526.41 points in the previous session. 

Similarly, the wide-based National Stock Exchange Nifty declined by 14.15 points, or 0.25 per cent, to 5,641.75. 

Brokers said sustained capital outflows from foreign funds amid a weakening trend in the global market after the US Federal Reserve signalled a possible end to its stimulus programme, mainly dampened the trading sentiment.

Besides, weakening rupee too triggered selling pressure, they added.
