ICICI Prudential Life Insurance Company’s stock spurted 4.5 per cent on Wednesday in reaction to good performance on the VNB (value of new business) margin and operational cost control front in FY18 (including the March 2018 quarter). Many analysts have not only upgraded the stock rating (Citi Research, Prabhudas Lilladher) to ‘buy’ from ‘neutral’ or ‘accumulate’ but also raised the target price by 14 per cent to an average ₹525.
