I have a simple question. What are the issues if someone opts a single AMC’s MFs for his MF portfolio. For example if I want to have a portfolio with HDFC Top 200, HDFC MIP LTP, HDFC Midcap Oppertunities, HDFC Balanced. These four belong to different category of MF (large cap, debt aggressive, midcap/small cap, multicap) and if i compare them with other AMC’s MF in the same category there is not much performance difference. Any thought on it?
