Which index mutual funds are good to invest for 3 to 5 years?

3 to 5 yrs is a small duration for any MF to generate wealth, especially when we’re expecting some consolidation after a fantastic 3 yrs bull run. My allocation would be -

1. 50% in Nifty50 index - UTI nifty index fund is a good option with min tracking error, low cost
2. 25% in Nifty Next50 index - Potential alpha opportunities, Navi and other fund houses have offering in this bucket
3. 25% in Nasdaq 100 FoF - FAANGs will lead the equity world sooner than later. Gives you benefit of currency fluctuations, 2024 might be a wavy year for Indian equities due to LS elections.
