You must invest in a scheme depending upon the investment philosophy of the scheme and a fair idea on the investment competence of the fund manager involved.
No one can doubt the ability of the Mirae equity fund management team in providing robust, top of the category returns to its investors. However an NFO is a different kettle of decisions altogether.
My thoughts in this is quite simple. I will invest in an NFO if the idea of the scheme does not exist in my portfolio. If it does, I would wait for a year to watch how it pans out. There is no gaurantee for a scheme to make its mark just because other schemes from the same stable have done very well.
I hope that clears the air.
