Tata Mutual Fund — huge fall in nav on 19/09/2018 of tata short term bond fund

Address:

Mumbai City, Maharashtra

Sirs,
There is a huge fall in nav of tata short term bond fund on 19/09/2018 and we have lost heavily. We pay the highest expense ratios and yet the funds are grossly mis-managed.
Mr murthy nagarajan was not there? This could have been easily avoided.
As investors, we would like to know the details of this fall and the integrity of procedure followed in investments.
