Minimum Duration Rule
Equity needs time to stabilize volatility. Follow these minimum holding periods:
| Fund Type | Min Duration | Reason |
|---|---|---|
| Large Cap / Index | 5-7 Years | Lower volatility, stable returns |
| Mid Cap | 7-10 Years | High volatility, needs time |
| Small Cap | 10-15 Years | Extreme moves, massive long-term gains |
| Debt Funds | 3-5 Years | For medium-term goals |
Common SIP Mistakes
Pays tax immediately, kills compounding. Always choose Growth.
Misses the best accumulation phase. Big loss.
Buying 15 funds dilutes returns. Stick to 3-5.
Inflation eats static SIPs. Step-up 10% annually.
Waiting for bottom usually means missing the rally.
Redeeming for small expenses like phones kills wealth.
