India’s growth too will be impacted by a global slowdown but India will be the least impacted large economy. This environment coupled with the resources of DIIs and retail investors can hold the market in good stead and can take it to new record highs, but high valuations are a concern," he added.Investors can approach Samvat 2079 with cautious optimism and remain invested in high-quality stocks and buy on declines in performing sectors like banking, capital goods, telecom and autos, advised Vijaykumar.In the 30-pack Sensex,, Dr Reddy’s Labs, Infosys,andwere the top gainers, rising about 0.5-1%., Reliance,, M&M,andalso opened higher.Sectorally, Nifty Auto added 0.60% and Nifty Metal rose 0.33%.
