Mumbai: The BSE benchmark Sensex fell by over 127 points in opening trade on Wednesday on emergence of profit selling by funds and retail investors amid a weakening trend on Asian bourses.

Likewise, the wide-based National Stock Exchange Nifty shed 43.20 points, or 0.76 percent, to 5,661.40.
Brokers said Sensex rose as funds and retail investors indulged in profit-selling amid a weak trend on Asian bourses following overnight losses at the US market.
They said US stocks fell on Tuesday, led by losses in technology, after brokerage downgrades major companies as worries increased about third-quarter US earnings.
