SIP vs Lump Sum: Dollar-Cost Averaging vs All-In
**Lump sum** invests everything now—historically wins in rising markets but feels risky before dips. **SIP (DCA)** spreads entries, reducing timing regret but may lag if markets trend up throughout the period.
Step by step
1. Define horizon
Long horizons favor staying invested; DCA mainly smooths entry over 6–24 months.
2. Compare scenarios
Model lump sum vs equal monthly buys with the same total capital.
3. Account for fees
Per-trade fees hurt small SIP slices—use low-cost funds where possible.
Lump sum vs SIP
Behavior matters: DCA is often a risk-management choice, not pure return maximization.
- Lump sum: Full market exposure immediately; best ex-post in bull runs.
- SIP / DCA: Lower average entry volatility; may miss early gains.
Common mistakes
- Stopping SIP after one bad month
- Ignoring opportunity cost of cash waiting to deploy
