The Nifty futures were trading lower at 9,245 on the Singaporean Exchange, indicating a weak start for the BSE Sensex and Nifty 50 on Thursday. Foreign institutional investors (FIIs) sold shares worth Rs 283.43 crore, while domestic institutional investors (DIIs) bought shares worth Rs 232.65 crore on net basis on Wednesday, according to the provisional data available on the National Stock Exchange (NSE). “The global weakness and first round of stimulus announcements are not being encouraged with respect to markets so we expect a weak opening. Failure of crossing key resistance of 9500 levels yesterday and weekly expiry will further increase volatility,” Vikas Jain, Senior Research Analyst, Reliance Securities, said.
