SYDNEY, Feb 10 (Reuters) - Index provider MSCI said it has cut the free-float designations of four securities of India's Adani group, a move which analysts have warned could impact their index weightings. MSCI said in a statement it has reduced the free floats of Adani Enterprises (ADEL.NS), Adani Total Gas (ADAG.NS), Adani Transmission (ADAI.NS) and ACC (ACC.NS). The remaining companies' free floats will remain the same. The four companies for which the free float designation change was announced had a combined 0.4% weighting in the MSCI emerging markets index as of Jan. 30. Analysts had said a change in free float status could affect the weightings of MSCI index constituents, possibly triggering a shift by funds as many investments are aligned to such indexes.
