Index of Eight Core Industries shows mixed sectoral growth with energy and refinery gains offset by crude oil decline. The Index of Eight Core Industries (base 2011-12=100) shows mixed sectoral movements in April 2019 with overall positive cumulative growth for April-March 2018-19. Coal, Electricity, Refinery Products and Steel supported aggregate gains, while Crude Oil declined and Natural Gas and Fertilizers recorded marginal or negative movements. Industry weights are drawn from IIP and scaled to a combined index of 100; electricity data include renewables and recent months are provisional.
