Navigating the world of asset allocation can be overwhelming given the myriad of available strategies. To make sense of it all, it's useful to study some tried-and-true models that have been developed by notable investors and financial thinkers.

60/40 Allocation

The 60/40 strategy is one of the most widely recognized and utilized asset allocation models, particularly popular among individual investors and financial advisors. The strategy suggests allocating 60% of an investment portfolio to equities, which are known for their growth potential but also come with higher volatility.

The remaining 40% is invested in bonds, which offer a stable income stream and less price fluctuation. The balance between the two asset classes aims to provide a risk-mitigating factor, offsetting the volatility of the stock market with more stable bond investments. This allocation is commonly recommended for those with moderate risk tolerance and a long-term investment perspective.

"Investing is a long-term endeavor. The longer the perspective, the clearer the vision."
Guillermo Larrain

Harry Browne's Permanent Portfolio

Conceived by Harry Browne in the 1980s, the Permanent Portfolio aims to deliver consistent performance under any economic condition.

By allocating an equal quarter of the portfolio to stocks for growth, long-term bonds for income, gold for inflation and crisis hedging, and cash or cash equivalents for liquidity and deflation protection, Browne’s model attempts to create an "all-weather" portfolio. Ideal for investors who prefer a "set it and forget it" approach, it aims to protect capital while still offering a reasonable growth opportunity.

"The Permanent Portfolio is not built to maximize returns; it is built to minimize regret."
Harry Brown

Ray Dalio's All Weather Portfolio

The All Weather Portfolio is built on the principle of risk parity, an approach popularized by hedge fund manager Ray Dalio. Unlike traditional asset allocation models that focus solely on asset classes, risk parity aims to balance risks, considering both historical performance and correlation of assets.

This diversified portfolio includes long-term bonds, short-term bonds, equities, commodities, and even gold. It seeks to offer investors lower risk without sacrificing potential returns. This strategy is well-suited for those who are a bit more sophisticated in their investment approach and are willing to manage a wider range of assets.

"Financial markets are the lifeline of an economy. Diversifying your assets is like diversifying a country's income streams—both are essential for resilience."

David Swensen's Yale Model

Developed by David Swensen, the Chief Investment Officer of Yale University’s endowment fund, the Yale Model shifts the asset allocation conversation towards alternative investments. By allocating a significant portion of the portfolio to assets like real estate, private equity, and hedge funds, Swensen aims to achieve higher returns and better diversification.

This strategy relies on the idea that non-traditional asset classes can offer low correlations to traditional stocks and bonds, reducing overall portfolio volatility. It is a strategy best suited for more experienced investors or institutions who have access to these kinds of alternative investments.

"Investment opportunities are cyclical. The question is not whether they will come, but whether you'll be prepared when they do."

Warren Buffett's Long-term Stock Holding

Warren Buffett, the Oracle of Omaha, practices a unique form of asset allocation that's more concentrated but well-reasoned. Rather than spreading investments across a wide range of asset classes, Buffett invests in a select few companies that he understands deeply and believes have long-term value.

This approach requires a high degree of confidence and in-depth knowledge of the companies invested in. It’s a strategy that takes a very long-term perspective and is often cited as better suited for investors who have a strong understanding of individual companies and a high tolerance for risk.

"If you have trouble imagining a 20% loss in the stock market, you shouldn't be in stocks."
Jack Bogle

John Bogle's Market Cap-Weighted Portfolio

As the founder of Vanguard Group, John Bogle revolutionized the investment world with his promotion of index funds. His strategy is based on the belief that beating the market is hard and costly. Therefore, he recommends buying a broad index fund that mirrors the market, essentially buying the entire stock market at very low cost. His approach offers a highly diversified exposure to equities, capturing market returns and minimizing the risks of picking individual stocks.

"You have to be in the market to capture the upturn, but if you’re in the market you’re going to get hammered by the downturn."
David Swensen

Global Tactical Asset Allocation (GTAA)

Global Tactical Asset Allocation is a more dynamic and flexible strategy that aims to take advantage of short-term market inefficiencies. GTAA managers use a variety of economic indicators, trends, and asset valuations to shift weightings between asset classes, countries, or sectors.

This is a strategy often employed by hedge funds and other sophisticated investors who have the resources and expertise to monitor global markets closely. It seeks to provide returns that are less correlated with major market indices, adding a layer of diversification to an investment portfolio.

"The biggest mistake investors make is to believe that what happened in the recent past is likely to persist."
Ray Dalio
