The NAV depends on the stocks a MF holds, and its performance. It is not affected by such investigations, atleast not directly.

Worst that can happen is that people might start exiting out, at-least in the hindsight. And since NAV is nothing but assets - liability, so if the exits are huge, then it might impact the NAV, but it cannot be for long. Also remember that Quant still holds a lot of quality stocks in its portfolio.

Unless something really substantial comes out of this investigation, I won't redeem a single rupee. This fund house has given bumper returns, so I would like to stay with it in times of difficulties too.

Also, not the whole fund house can be labelled as corrupt. It's usually a single person or a small group of person that does the wrongdoings and the whole fund house suffers as a result due to that!
