Zomato is expected to witness inflows of about $513 million next week after the food delivery giant enters BSE Sensex's 30-share frontline index on December 23, brokerage firm Nuvama said. The inclusion would make Zomato the first new-age tech stock to enter the 30-share frontline index. It will replace JSW Steel, whose exclusion will lead to $252-million outflows, Nuvama added.
