I have choosed: 1) Zerodha Nifty Large Midcap Index 250 2) JM Flexicap 3) Tata Small Cap 4) Motilal Oswal Nifty Microcap 250 Index 5) SBI Direct Gold. Is this correct diversification or can I choose Motilal Large Midcap or Edelweiss US Tech FOF instead of Motilal Nifty Microcap I was thought of seeing Nasdaq 100 as this above alternative in Nasdaq 100 no fund is there now to invest all has been freezed.
