Hi,
I think only three funds hdfctop200,dsptop100 and reliance growth will be enough. These 3 funds cover large and midcap. also they keep rotating sectors gradually and not frequently. Another feature is that dsp and reliance take cash calls to protect downside. All three are rated 4/5 star consistently and standard deviation is low compared to peers.
Gold ETF should be 10%. Debt and equity funds allocation is a function of risk profile.
