Want to invest lumpsum in MIP and do STP to Equity Fund for 20 years

Your idea of doing STP for 20 years is a great one. However, you should avoid investing lumpsum in MIP for the sole purpose of doing STP. Since MIPs invest 20-30% in equities they could be volatile and might also have negative returns when equity markets are not doing that great. For doing STP, you should always go for Liquid funds for lumpsum investments and the transfer to a Diversified Equity Fund or Balanced Fund depending upon your risk taking ability.
