How long will it take for the mutual fund units to show up in my portfolio?

It will take up to one trading day for the invested mutual fund units to reflect in your portfolio.

For example, If you have made the investment on Monday before cut off time, the units will be allotted to you by Tuesday or the next working day if it is followed by a holiday.

The NAV (Net Asset Value) for the units allotted will be as on the day you place your trades.
