What Is Systematic Investing?
A Systematic Investment Plan (SIP) or Dollar-Cost Averaging (DCA) is a strategy of investing a fixed amount of money at regular intervals, regardless of market conditions. Instead of trying to time the market, you invest consistently over time.

How Dollar-Cost Averaging Works
When you invest $500 monthly:
- When prices are high: You buy fewer shares
- When prices are low: You buy more shares
- Over time: Your average cost per share tends to be lower
Example
| Month | Investment | Price | Shares Bought |
|---|---|---|---|
| January | $500 | $50 | 10.00 |
| February | $500 | $40 | 12.50 |
| March | $500 | $45 | 11.11 |
| April | $500 | $55 | 9.09 |
| Total | $2,000 | Avg: $46.88 | 42.70 |
Average price was $47.50, but your average cost was $46.88 per share because you bought more shares when prices were lower.
Benefits of Systematic Investing
- Removes Emotion: No need to decide "is now a good time?"
- Reduces Timing Risk: Avoids investing everything at a market peak
- Builds Discipline: Automatic investing becomes habit
- Accessible: Start with any amount you can afford
- Compounds Over Time: Regular contributions add up significantly
- Lower Average Cost: Buy more shares when prices drop
Setting Up Automatic Investing
- Determine your amount: What can you invest monthly without stress?
- Choose your frequency: Weekly, bi-weekly, or monthly
- Select investments: Index funds and ETFs work well for DCA
- Set up auto-transfer: Link bank account to brokerage
- Enable auto-invest: Most brokers offer this feature
DCA vs Lump Sum Investing
Research shows lump sum investing beats DCA about 66% of the time because markets generally rise. However, DCA:
- Reduces regret if markets fall after investing
- Is more practical (most people don't have large sums)
- Matches how income is earned (regular paychecks)
- Provides psychological comfort
Best Investments for DCA

- S&P 500 Index Funds: Large-cap US stocks
- Target-Date Funds: All-in-one solutions
- Broad Bond Funds: Fixed income portion
