V K Vijayakumar, chief investment strategist at Geojit Financial Services, said the fundamental support to the market comes from the resilience of the US economy, the declining US bond yields and the hope that the Israel-Hamas conflict will remain a localised crisis which will not impact crude prices. "The fact that Nifty is just 2.5 per cent away from the all-time high indicates the strength and resilience of the market. Even though FIIs are sustained sellers in the market, buying by DIIs, HNIs and retail are counterbalancing the selling and supporting the market. Safety is in large-caps," he noted. DIIs and HNIs refer to Domestic Institutional Investors and High Networth Individuals, respectively.


Asian markets, including Japan, China and Hong Kong, were trading with gains. European and US markets closed in the green on Tuesday. 


Foreign Institutional Investors (FIIs) continued to be net sellers as they offloaded shares worth Rs 1,005.49 crore on Tuesday, according to data available with BSE.

However, selling pressure from foreign equity investors weighed on the Indian currency, forex traders said.
