Mumbai: Tracking weak Asian markets, Sensex today fell by 72 points to 16,846.05, its lowest closing since June 18, amid concerns over deficient monsoon and delay in key economic reforms.
Brokers said investors were also cautious ahead of the monthly settlement in derivatives segment on Thursday.
After opening marginally lower, the BSE benchmark index fell to the day's low of 16,736.60 -- close to 110 points down compared to yesterday's close.
