What Is Asset Allocation?

The asset allocation decision divides total investable funds by percent into specific investment categories. An asset allocation represents the investor’s choice of broad asset classes and the percentages distributed across the categories.
The two most common asset classes are stocks and fixed-income investments, including bonds and cash. Although your investment mix can include crypto, commodities and alternatives as well.
Based upon the seminal study by Brinson, Hood, and Beebower, “Determinants of Portfolio Performance”, from the August 1986 Financial Analysts Journal, asset allocation is widely considered one of the largest contributors to a portfolio’s return.
In other words, the individual stocks, bonds, and funds you choose, or when you buy and sell them, are less important to your ultimate return than the percent allocated to various asset classes. That still doesn’t answer the question, “What is the best asset allocation for you?”
If you invest in a diversified mix of 50% in stocks and 50% in bonds, your return will closely approximate the market return of 50% stocks and 50% bonds.
Asset allocation is very important because it creates portfolio diversification and reduces an investment portfolio’s risk.
Adjust the Classic Advice to Find Your Best Asset Allocation
The classic asset allocation advice is very simple:
Take your age and subtract it from 100. Then invest the resultant percent in stock assets with the remaining percent in fixed assets.
If you are 40 years old, according to the classic advice, you should have 60% in stocks and 40% in fixed assets. Like the graph above. (100-40 years old=60% stock assets)
We’re living a lot longer than previous generations. That’s why the updated best asset allocation strategy is to subtract your age from 120 and use the remainder to invest in stocks.
If you’re 50 years old, subtract that from 120 and you’re left with 70. So the new thinking suggests a typical 50-year-old should have 70% of her assets in stock investments and 30% in bonds.
This advice is a good starting point, but incomplete.

Know Your Risk Tolerance and Risk Capacity
Risk Tolerance
The historical wisdom suggests that if you are young, with many working years ahead, you are more risk tolerant. This theory goes on to imply that if you suffer a big loss in your investment portfolio at age 30, you have many working years ahead to replace the lost funds. Thus, younger investors are typically advised to own more stocks and less bonds since stocks offer the prospect of greater long-term returns (albeit with more risk).
What happens when the market tanks?
Your portfolio = 70% Stocks and 30% Bonds
Imagine this scenario: It’s the end of 2008, you are 30 years old and your investment portfolio holds 70% stock mutual funds and 30% bond mutual funds. Your stock funds fall 33.8% (Dow Jones Average 2008 loss), the worst drop since 1931, according to an ABC News report. (And if you were especially unlucky, your General Motors stock fell 87.1%.)
2008 is an example of stomach churning investment losses.
Fortunately, the bond portfolio (proxy; Barclay’s aggregate bond index) returned 5.24% in 2008.
Thus, if you invested 70% in a Dow Jones index fund and 30% in a diversified bond index fund, your return in 2008 would have been; -22.09%. ((.70 x -.338) + (.30 x .0524))
If you had a $25,000 portfolio on January 1, 2008, on December 31, 2008 the value would have fallen to $19,478. In a single year, your portfolio would have lost approximately $5,522.
Although a 22% loss isn’t great, it’s a better return than that of an all stock portfolio.
Had your stock fund been invested in a broader market index, the Standard and Poor’s 500 in 2008, your stock allocation loss would have been a whopping 36.55%.

Consider a ‘worst case scenario’ and do a gut check.
Regardless of your age, if you are extremely risk averse and cannot tolerate drops in your portfolio value, you may want a greater percentage in fixed/bond assets and a lesser percent in stocks.
Michael Kitces, a well-known investment advisor and prolific writer alleges that risk tolerance is stable and can be measured. There are a variety of online risk tolerance quizzes, but equally important as taking a quiz is to imagine how you would feel if your investment values fell various percentages. Because you want to avoid one of the worst investing mistakes; to panic after a market drop, and sell. That locks in your losses and robs you of the chance to enjoy the upswing as stock and bond prices rebound.

Your age doesn’t always correlate with your risk tolerance.
Many young investors cannot tolerate anything more than a small decline in their portfolios. So, more risk averse investors might need a greater percent in fixed assets.
Risk Capacity
Risk tolerance measures how comfortable you are with market ups and downs. Risk capacity, on the other hand, measures your financial ability to withstand investment losses. Even investors who are comfortable taking risk may not have the financial capacity to do so.
For example, someone with a stable job, a large emergency fund, little debt, and many years before needing their investment money generally has a higher risk capacity. In contrast, an investor approaching retirement, relying on their portfolio for income, or working in an uncertain industry may have a lower risk capacity and should consider a more conservative asset allocation.
Before deciding on your stock and bond allocation, ask yourself:
- How soon will I need this money?
- Do I have adequate emergency savings?
- Is my income stable and predictable?
- Would a significant market decline force me to sell investments?
- Am I nearing retirement or another major financial goal?
The best asset allocation balances all three factors: your age, your risk tolerance, and your risk capacity. When those factors are aligned, you’re more likely to stay invested during market downturns and achieve your long-term financial goals.
What Is the Best Age-Based Asset Allocation and Risk Tolerance?
The best asset allocation for you should consider your age, risk tolerance, how long you expect to work, your future earning power (your human capital) as well as where you work. If you work in the investment industry, you may want to direct a lower percent towards stock investments. That’s because your job is dependent upon the financial markets. You do not want to experience a drop in your stock portfolio and a layoff because the market tanked.
If your income is erratic or uncertain, consider maintaining a larger cash cushion.

Best Asset Allocation Funds
If you’re seeking a set-it and forget-it path to asset allocation, you might consider an asset allocation fund. Within one mutual fund or exchange traded fund, you get a completely diversified portfolio of stocks and bonds. Some asset allocation funds are designed for investors with varying risk-tolerances. For example, a conservative asset allocation fund would own more fixed income and bonds and a smaller percent of stock assets. While the aggressive asset allocation fund would be stock-heavy, with only a small allotment to more conservative bond funds.
Target date funds are a distinct type of asset allocation funds. You buy a target date fund, with a date that corresponds with the year you expect to retire. If you’re 35 and expect to retire at age 65, then you’ll buy a target date 2055 fund. The fund adjusts the portfolio allocation by age. The stock and bond allocation become more conservative as the retirement date approaches. Many 401(k) and employer-sponsored retirement accounts offer target date funds among their investment choices.
M1 Finance offers a range of asset allocation funds in their “expert portfolios.”
Asset Allocation Action Steps
1. Spend a bit of time understanding yourself and the markets. If you’re interested in an excellent 100-page book on investing, I recommend The Elements of Investing, by Malkiel and Ellis.
2. Take a risk tolerance quiz and assess how you will feel when your portfolio experiences an inevitable cyclical decline.
3. Create an asset allocation considering your age, risk tolerance, security of your job, and industry. If your job is insecure, you may want smaller allocations to stocks and bonds and more in cash assets.
