Index of Eight Core Industries shows year-on-year growth, with mixed sectoral performance and provisional data noted. The Index of Eight Core Industries (base 2011-12) records a year on year increase in January 2018 and positive cumulative growth for April-January 2017-18. Sectoral performance was mixed: petroleum refinery products, cement, electricity and steel showed notable positive monthly growth, while crude oil, natural gas and fertilizers declined; coal rose modestly. The release includes monthly and cumulative indices and growth rates, states recent months' data are provisional, and notes renewable electricity is included and weights are scaled from the IIP.
