60/40 Portfolio
The classic balanced portfolio
Philosophy
Balance growth potential with stability by splitting assets between stocks and bonds.
Origin
1952 — Born from Modern Portfolio Theory, the 60/40 portfolio became the benchmark balanced allocation.
Key Principles
- ✓ Stocks drive long-term growth, bonds provide ballast
- ✓ Imperfect correlation between stocks and bonds reduces overall portfolio volatility
- ✓ Periodic rebalancing forces a buy-low, sell-high discipline
- ✓ Simplicity makes it easy to implement and maintain
Target Allocation
| Asset | Category | Weight |
|---|---|---|
| US Stocks | Equity | 60% |
| US Bonds | Bonds | 40% |
Advantages
- Extremely simple to implement and understand
- Long track record of solid risk-adjusted returns
- Low maintenance — rebalance once or twice a year
- Very low cost with index funds
Considerations
- Bonds may underperform during rising rate environments
- No downside protection mechanism beyond diversification
- Concentrated in US assets
- Less upside capture than 100% equity portfolios

Frequently Asked Questions
What is the 60/40 portfolio?
The 60/40 portfolio allocates 60% to stocks and 40% to bonds. Rooted in Modern Portfolio Theory by Harry Markowitz (1952), it balances growth and stability through the imperfect correlation between the two asset classes.
Is the 60/40 portfolio still a good strategy?
The 60/40 portfolio remains a solid starting point for balanced investors. While rising interest rates can hurt the bond portion in the short term, the long-term diversification benefit between stocks and bonds continues to reduce overall portfolio volatility.
How often should I rebalance a 60/40 portfolio?
Quarterly or annual rebalancing both work well. The key is maintaining discipline — rebalancing forces you to sell winners and buy underperformers, which improves long-term risk-adjusted returns.
