This is completely at the discretion of the Asset management company, one cannot really time this.

As and when the expense ratio reduces, the return on your investment increases. Btw, as far as I know, such changes in expense ratio is not very common.

Hello @Karthik sir,@siva
Is there any correlation between Expense ratio and the AUM of MF(I.e whether increase or decrease of AUM effects the ER?) .I have seen same AMC increasing the Expense ratio in one quarter and then decreasing it few quarters later. What decides the ER change? Is it one of the check that investors have to do to filter out MF’s during fund selection?
