After rising more than 4 per cent in the previous session, oil prices fell on Tuesday as traders exercised caution and kept an eye out for any possible supply interruptions caused by the armed hostilities between Israel and the Palestinian Islamist group Hamas. The International Monetary Fund (IMF) stated in its October 2023 World Economic Outlook report that India's economic growth forecast for the current fiscal has been changed from 6.1 per cent to 6.3 per cent.

Vinod Nair, Head of Research at Geojit Financial Services, said the Indian market completely recovered Monday's losses which were mainly due to the Hamas-Israel conflict. Moderation in crude prices and positive global cues on account of dovish remarks from Fed officials, which restrained US bond yields, aided the rebound. The domestic market's primary focus is currently on the approaching results season, with optimistic expectations on earnings, Nair said. /IANS
