The 90/10 investing strategy is an asset allocation model popularized by Warren Buffett. This strategy recommends allocating 90% of investment capital to stock index funds and 10% to short-term government bonds. The primary objective is to achieve significant growth through equities while maintaining a safety buffer with bonds.
Mechanics of the 90/10 Strategy
Allocation Breakdown
-
90% in Stock Index Funds: Stock index funds typically track major indices like the S&P 500. This allocation aims to mirror the overall market performance, benefiting from the long-term growth potential of equities.
-
10% in Short-Term Government Bonds: Short-term government bonds provide stability and liquidity. These bonds are considered low-risk, helping to mitigate volatility and provide quick access to funds if needed.
Implementation Steps
- Determine Initial Capital: Assess the total amount available for investment.
- Calculate Allocations: Allocate 90% to stock index funds and 10% to short-term government bonds.
- Rebalancing: Periodically review and adjust the portfolio to maintain the 90/10 allocation ratio, especially after significant market movements.
Benefits of the 90/10 Strategy
Growth Potential
The majority allocation to stock index funds leverages the long-term capital appreciation of the stock market. Historically, equities have provided higher returns compared to bonds.
Simplicity
The 90/10 strategy is straightforward and easy to implement, making it suitable for individual investors who prefer a simple yet effective approach.
Low Costs
Investing in index funds often results in lower fees and expenses compared to actively managed funds, contributing to higher net returns over time.
Drawbacks of the 90/10 Strategy
Volatility
A 90% equity allocation can lead to significant portfolio volatility, especially during market downturns. Investors must have a high risk tolerance to endure potential fluctuations.
Limited Diversification
The strategy primarily focuses on market index performance, which might overlook other critical asset classes such as real estate, commodities, or international investments, reducing overall diversification.
Liquidity Risk
While short-term bonds provide some liquidity, the heavy reliance on equities could pose liquidity risks during severe market corrections.
Historical Context
Warren Buffett’s 90/10 strategy gained prominence through his annual letters to Berkshire Hathaway shareholders. He advised his trustee to use this model for his wife’s inheritance, emphasizing his confidence in the long-term growth of the stock market and the stability of government bonds.
