IT, agro chemical, pharma and select infra/real estate companies are likely to be in focus, he noted. Further, Wall Street remained resilient throughout last week amid possibility over fiscal stimulus and fading uncertainty over outcome of election, he said, adding that the fiscal stimulus talk should continue to offer support to emerging equities.
