Portfolio Overview
The 60/40 portfolio is a classic investment strategy designed for steady, long-term growth with moderate risk. With a balanced allocation of 60% in stocks and 40% in bonds, this portfolio is a popular choice among investors looking for growth potential without extreme volatility. The 60/40 portfolio split between equities and bonds has historically provided stability during market downturns, while still benefiting from bull markets.
The 60% allocation typically goes into equities through an ETF like SPY, which tracks the S&P 500, giving exposure to large-cap U.S. companies. The remaining 40% is allocated to bonds, such as through the TLT ETF, which focuses on long-term U.S. Treasury bonds. This blend offers a mix of growth from stocks and defensive benefits from bonds, aiming to achieve smoother returns across various market cycles.

Asset Allocation
The classic 60/40 portfolio is a straightforward blend of two main asset classes, providing a balanced approach that adjusts well to different market environments:
- U.S. Stocks (60%): Exposure to large U.S. companies is achieved by investing in the SPY ETF, which tracks the S&P 500. This portion of the portfolio provides growth, capitalizing on the overall performance of the stock market.
- Bonds (40%): Long-term U.S. Treasury bonds, typically through the TLT ETF, offer stability and lower risk. Bonds generally perform well during periods of market stress, helping balance out the more volatile stock component.
This simple mix keeps the portfolio easy to manage while offering broad diversification. The equities provide growth, and bonds add a layer of defence, creating a more predictable investment experience over time.
