| ETF | Allocation |
|---|---|
| SPDR S&P 500 ETF Trust (SPY) | 2% |
| Vanguard Total Bond Market ETF (BND) | 2% |
| iShares Core U.S. Aggregate Bond ETF (AGG) | 2% |
Risk-Return Analysis: Taking it to the Next Level
While the 2% Rule is a good starting point, I’ve found that a more nuanced approach is necessary for maximizing returns while managing risk. That’s where risk-return analysis comes in.
| ETF | Potential Return | Potential Risk | Allocation |
|---|---|---|---|
| SPDR S&P 500 ETF Trust (SPY) | 8% | 12% | 3% |
| Vanguard Total Bond Market ETF (BND) | 4% | 6% | 2% |
| iShares Core U.S. Aggregate Bond ETF (AGG) | 3% | 5% | 2% |
Position Sizing Based on Market Conditions
Another important consideration is the overall market conditions. During times of high volatility or uncertainty, I reduce my position sizes to minimize potential losses. Conversely, when the markets are trending strongly, I may increase my position sizes to maximize returns.
| Market Conditions | Position Sizing Adjustment |
|---|---|
| High Volatility | Reduce position sizes by 25-50% |
| Low Volatility | Increase position sizes by 25-50% |
| Bull Market | Increase position sizes by 50-100% |
| Bear Market | Reduce position sizes by 50-100% |
The Importance of Rebalancing
Finally, rebalancing is a critical component of any position sizing strategy. As the markets move and my ETF positions fluctuate in value, I regularly rebalance my portfolio to maintain my target allocations.
| ETF | Initial Allocation | Current Allocation | Rebalancing Adjustment |
|---|---|---|---|
| SPDR S&P 500 ETF Trust (SPY) | 3% | 3.5% | Sell 0.5% |
| Vanguard Total Bond Market ETF (BND) | 2% | 1.5% | Buy 0.5% |
| iShares Core U.S. Aggregate Bond ETF (AGG) | 2% | 2.2% | Sell 0.2% |
