Procedure

Set asset allocation by age and goalDefault: 100 - age in equity %. Adjust by horizon and tolerance. Long-term: 70-80% equity. Medium-term: 50-60%. Short-term: 20-30%.
Define equity sub-allocationCore (large-cap / flexi-cap): 50-60% of equity. Mid-cap satellite: 15-25%. Small-cap satellite: 5-15%. International: 5-15%. ELSS (if 80C used): part of equity.
Define debt sub-allocationLiquid (emergency / cash-bucket): 10-30% of debt. Corporate Bond / Short Duration (medium-term): 50-70%. Long Duration / Gilt (long-term): 0-20%.
Optional: gold + internationalGold: 5-10% via Gold ETF / SGB. International: 5-15% via Nasdaq / S&P 500 fund.
Pick one scheme per categoryDon’t fragment: one large-cap, one flexi-cap, one mid-cap, one corporate bond, one liquid. Optional: one international, one gold.
Set up SIPs across schemesMonthly SIPs proportionate to target allocation. 10% annual step-up.
Annual rebalanceOnce a year: check actual vs target. Drift > 5pp: redirect new SIPs or switch via STP.
Glide path as goal approachesReduce equity over last 3-5 years before goal. Move to debt and balanced advantage.

Balanced MF portfolio with 4-5 funds covers all asset classes without fragmentation. More funds doesn’t mean more diversification; it usually means costly index replication.
