Foreign institutional investors purchased shares worth Rs 926.60 crore in the capital market on Thursday, while domestic institutional investors sold equities worth Rs 635.59 crore, data available with stock exchange showed.
Despite positive cues from global markets and sustained foreign fund inflow, domestic equities turned negative after Moody's Investors Service lowered the outlook on India's credit ratings, traders said.
The agency has changed the outlook on India's ratings to 'negative' from 'stable', saying there was increasing risks that economic growth will remain materially lower than the past.
While the government's recent measures to support the economy should help to reduce the depth and duration of India's growth slowdown, prolonged financial stress among rural households, weak job creation, and, more recently, a credit crunch among non-bank financial institutions (NBFIs), have increased the probability of a more entrenched slowdown, it said.
