The Bombay Stock Exchange (BSE) has added liquid schemes of Reliance Mutual Fund to its StAR MF platform, which was launched on December 4, 2009. The idea is to facilitate investors to earn higher returns on surplus funds, BSE said in a statement. This addition would provide an additional option to the retail investors, institutions and other mutual fund participants, to park their overnight surplus funds and earn higher interest. Liquid schemes run by AMCs usually invest in money market and other permissible debt instruments. For all transactions in liquid schemes through the StAR MF platform, the subscription units will be computed on the basis of the NAV of the day prior to the one on which the funds are received by the AMC from the exchange. The StAR MF platform has seven AMCs and over 300 scheme options.
