The Nifty fell 1.5 % on Friday, marking its biggest single-day fall in nearly 3-1/2 weeks as blue-chips such as Reliance Industries slumped tracking weaker global markets ahead of US jobs data later in the session. The BSE Sensex lost 1.6 %, or 414.13 points, to end at 25,480.84.
While encouraging for the global economy at large, strong US employment data would strengthen the case for an early interest rate hike by the Fed, whose monetary largesse has helped fuel a 45 % rally in global stocks over the past two years.
This caution was magnified in India after overseas investors sold shares worth 16.54 billion rupees ($273.2 million) on Thursday, their biggest single-day selling since July 2, according to provisional exchange data.
Markets virtually ignored a private survey on Friday showing factory activity expanded at its fastest pace in 17 months in July and data late on Thursday showing annual infrastructure sector growth hit a nine-month high in June.
Caution ahead of the Reserve Bank of India's policy review on Tuesday, its first since the new government's budget, where it is expected to leave its key interest rate unchanged, weighed as well.
"Global risk is weighing but India remains on an uptrend. Expectations for at least a dovish stance by RBI have also grown, so buy on dips," said Deven Choksey, managing director at K R Choksey Securities.
