3. Disciplined Investing: Wealth grows steadily over time.
4. Low Investment Start:Begin with just ₹100 to ₹500/month
5. Balanced Risk Reward: Better growth with manageable risk
6. Growth Focused Companies: Invest in rapidly expanding businesses.

5 Things to Check Before Choosing the Best Mid Cap Mutual Fund for SIP

Every investor should check the following 5 points, as not all mid cap funds are equal: 

1. Long Term Performance (5+ Years):One should focus on 5-10 year CAGR, not 1 year returns. The fund should consistently beat the Nifty Midcap 150 TRI across cycles.
2. Fund Manager Experience: Check how long the manager has run the fund and their track record in mid caps.
3. Portfolio Diversification: Prefer 40-65 stocks, and spread across sectors. Avoid heavy concentration in 1-2 sectors or weak quality businesses.
4. Expense Ratio: Lower is better so one should aim for <1.7% (regular) . 
5. AUM Size:  The ideal range is ₹8,000–₹25,000 crore, as too large (>₹30,000 crore) can reduce flexibility in mid cap investing.
