Expectation of lower interest rates with further liquidity infusion by the Reserve Bank of India (RBI) under its new chief, along with healthy macro-economic data points, drove the key equity indices forward. Initially, Indian equity market opened on dismal note, but a sharp bounce back after the five state Assembly election results drove the S&P BSE Sensex and the NSE Nifty50 to their fourth straight session of gains. "While the resignation (of RBI Governor Urjit Patel) took the market by surprise, leading to concerns over the independence of RBI as an institution, the quick announcement of the appointment of the new Governor (Shaktikanta Das) has helped allay these fears," said Shibani Kurian, Senior Vice President, Head of Equity Research, Kotak Mahindra Asset Management. The new Governor, former senior bureaucrat Shaktikanta Das, is seen close to the present dispensation at the Centre. Another key theme of the week was normalisation of Brent Crude oil price to around $60 after a short-term upward mobility due to OPEC production cut announcement. "Crude oil production cut by OPEC was below expectation which had sparked a short-term volatility, but normalised subsequently. Also, US inventories have gone down this week," Anuj Gupta, Deputy Vice President - Research, Commodities and Forex, Angel Broking, told IANS. Read | Check out!

However, towards the end of the week, advances were capped across the globe as growth concerns grew after China, the world's second-largest economy, reported slowing retail growth. Consequently, global equity markets ended the week on a negative note. In terms of investments, foreign institutional investors (FIIs) were net sellers during the review as they off-loaded a total of Rs 2,067.19 crore worth of shares, while domestic institutional investors (DIIs) sold scrips worth Rs 153.21 crore, provisional data from the BSE showed.
