Help me create a good portfolio for Mutual Funds.

Take advice of a competent financial planner, investment advisor. Most people here have no clue what they are talking about when it comes to finance. Market is irrationally overvalued. The real economic growth or earning doesn't justify the valuation. If you are entering the market for the first time, you may or may not have the gut to absorb a drawdown which will eventually come. Still if you want to invest do 10k sip each in nifty 50 and nifty next 50 index fund. 10k in a gilt fund and for the rest 10k buy ETF in international funds preferably hangseng bees ( that's the cheapest for now). You will not make great returns but you will sleep peacefully.

Quant for Small Cap,

Motilal Oswal for Mid Cap,

Parag Parikh for Flexi Cap

Invest only amount, which you dont need for emergency fund.

Look for 5+ year returns , not for 6m/1y/2y/3yrs.

Look for the Expense ratio and Exit load both should be less than 0.5% (Except parag parikh).

You can also invest in T-bills for good returns.

(1) One large cap

(2) One mid-cap

(3) One small cap

(4) One Parag Parikh flexi cap

Invest in ratios for eg : 25/20/15/40
