Conflicting signs from the US and China on the trade deal and the Reserve Bank of India’s status quo on rates put brakes on the bull surge as both the Sensex and the Nifty closed the week with losses of about 1 percent. The Nifty, which hit a record high of 12,158 last week, failed to hold onto the momentum and closed with losses of 1.1 percent for the week ended December 6. The Sensex, which rose to a record high of 41,163 last week, ended with losses of 0.85 percent for the week ended December 6.
