How to Construct an Investment Portfolio
We touched on the importance of portfolio diversification in the last post. In this post, we will take our portfolio discussion a step further and review some pointers that will assist in proper portfolio construction. This is important because most everyone has at least one investment account (most commonly in the form of a work retirement plan), but too few know the basics of putting together a balanced portfolio. I've witnessed firsthand how much excess risk (or even lack of risk) many investors are unknowingly taking in their accounts, so it's time we get a little more educated.
Here are 4 fundamental concepts that will help lay the groundwork towards construction of a solid investment portfolio:
1. Review Your Time Horizon
First, know that investing in stocks and bonds should not be considered a short-term journey. Stocks and bonds both have market risk, meaning you could potentially lose a significant amount of money in any given time frame. Let's take a look into what that means.
Dating back to 1947, the average bear market (period of a 20% or more market decline from previous highs) of the S&P 500 has lasted an average of 1.9 years (see chart attached). Let's assume the worst case scenario and say a person invested 100% of their portfolio in the S&P 500 right as a bear market kicks into gear. Assuming a 1.9 year slide followed by an average recovery period right around 3.5 years, this investor should not expect to be back to even until year 5 or 6. Being in a diversified portfolio could likely reduce this cycle, but I would still suggest that anyone with a 0-5 year time horizon keep their money out of the market entirely.
Here is a quick overview to help match your portfolio risk to your time horizon. Simply ask yourself: Will your portfolio funds be needed within the following time frame?
0-5 Years: Stay in cash/savings
5-10 Years: Explore a Conservative to Moderate risk portfolio
10+ Years: Explore a Moderate to Aggressive risk portfolio
2. Review Your Risk Profile
Once you've established your investment time horizon, you must now explore how much risk you can realistically handle as an investor. This requires complete honesty. An investment strategy is only as good as the investor's ability to be disciplined in its execution, so an incorrect evaluation of your risk tolerance can derail your potential for success before you even begin. Here are the different portfolio risk tolerance profiles. Which definition aligns most closely with your emotional convictions? Again, because it's worth repeating, be honest!
Conservative: Low risk tolerance, where the term risk means danger. When making a financial decision, this investor tends to focus on possible losses. Fluctuations in account value cause high stress.
Moderately Conservative: Below average risk tolerance, where the term risk means uncertainty. When making a financial decision, this investor is more focused on possible losses, but is also mindful of possible gains. Fluctuations in account value cause mild stress.
Moderate: Average risk tolerance, where the term risk means possibilities. When making a financial decision, this investor is more focused on possible gains, but is also mindful of possible losses. Fluctuations in account value are understood.
Moderately Aggressive: Above average risk tolerance, where the term risk means opportunity. When making a financial decision, this investor tends to focus on possible gains. Fluctuations in account value are expected.
Aggressive: High risk tolerance, where the term risk means excitement. When making a financial decision, this investor only focuses on possible gains. Fluctuations in account value are welcomed.
Review your time horizon, then apply the suggested risk profile which best describes you. Once complete, you are set to move forward to the next step.
3. Develop an Asset Allocation
In layman's terms, this means that you will be creating one of those super sweet looking pie charts for your portfolio. In order to do this, one must start from square one, which means first determining a baseline portfolio mix of stocks (equities) versus bonds (fixed income). Remember from the prior post, stocks have quite volatile movements (more risk) but tend to generate higher long-term returns, while bonds usually have a more stable path and predictable returns (less risk). Aggressive profiles should have more of an allocation to stocks, while conservative investors should have more exposure to bonds.
With your risk profile in hand (as determined in steps 1 and 2 above), use the chart referenced here to find your recommended stock/bond mix. For example, a moderate risk investor should match relatively well with a portfolio that consists of 55% stocks and 45% bonds. Of course, you can move up and down the scale as your wish. This chart is simply here to give you a baseline starting point.
Now take a breather, because we still need to dig a bit deeper into this asset mix. Sure, you could simply buy a broad U.S. stock fund for your stock exposure and a broad U.S. bond fund for your bond exposure and call it a day; however, we can diversify further to potentially generate better returns on our money. Let's first take a look into further diversifying our stock holdings.
To get a better handle on what true stock diversification looks like, it makes sense to first take a peek into an allocation of the global stock market. In other words, if you took one dollar and invested it across the entirety of the world's stock market, how would that dollar be split? A company named MSCI tracks this world stock market for us in an index called the MSCI ACWI (All Country World Index). I've included a pie chart of the index for reference. Notice that the United States makes up around 56% of the world’s stock market. If you invested solely in U.S. stock funds (which a lot of people do) you would be structuring your portfolio with a home country bias, and missing out some exciting growth potential from international markets. For this reason (and a few others too lengthy to review today), I would suggest that a better stock allocation in your portfolio more closely resemble this chart. Here is a breakdown of the global stock market:
U.S. Stocks: 56% of stocks
International Developed Stocks (Canada, Europe, Japan, etc.): 33% of stocks
Emerging Markets Stocks (China, India, etc.): 11% of stocks
For further bond diversification in a portfolio, an investor can again choose to look internationally. The chart referenced here by J.P. Morgan shows that the United States has only issued about 36% of the world's fixed income holdings. This makes a compelling case for adding international bond exposure. While added diversification can have benefits within bonds much like stocks, one must first remember that arguably the most important function of bonds in a portfolio is to provide protection (think insurance) against the volatility of stocks. Again, it's that non-correlation factor previously discussed. High-grade U.S. bonds do an excellent job of providing this protection and stability, most times better than international bonds. Therefore, the benefits of mass diversification in this sector are going to be somewhat muted compared to those same benefits you would find in stocks. For these reasons, a high-quality, U.S. broad market bond fund tends to work perfectly fine for most investors; especially if simplicity helps keep you on target. Sample parameters for a bond allocation mix are referenced here below.
U.S. Bonds: 36% - 100% of bonds
International Developed Bonds: 0% - 43% of bonds
Emerging Markets Bonds: 0% - 21% of bonds
4. Pick Your Holdings
With an effective asset allocation now understood, successful deployment of a quality investment portfolio is at your fingertips. The last hurdle lies in deploying the actual holdings that will accurately embody the asset classes you are trying to represent.
To best assist in properly covering your bases, you should invest in funds (mutual funds and/or Exchange Traded Funds) and not in individual stocks or complicated alternative assets. The latter will pose too much confusion and complication. Remember, simpler is almost always better. Also, try to target broad market index funds in an effort to reduce your investment expenses and increase the tax efficiency of your account.
Finding a fund to accurately represent each category can be tricky, so I'm giving you a quick and dirty reference list below. When scouring the available investment options within your work retirement plan or personal investment portfolio(s), seek a fund within each sector that includes some form of the following verbiage.
U.S. Stocks: S&P 500, Russell 1000, Total Stock Market
International Developed Stocks: FTSE Developed, MSCI EAFE, International Developed
Emerging Markets Stocks: FTSE Emerging, MSCI Emerging, Emerging/Developing Markets
U.S. Bonds: Aggregate Bond, Total Bond Market, Total Return
International Developed Bonds: International Aggregate Bond, Total International Bond, Global Bond
Emerging Markets Bonds: Emerging Markets Bond, Emerging Markets Income, Emerging Markets Debt
If unsure about the strategy of a particular fund, you might have to roll up the sleeves and do a little digging. You can do that by searching the fund in Morningstar and clicking on the "Portfolio" tab on the main page. A full breakdown of the fund and it's holdings will be summarized for you.
Lastly, and to keep things as simple as possible, don’t overlook investing in a high quality target date investment fund (such as those provided by Vanguard) or in an automated investment platform (such as Betterment). These services can place you a well-diversified array of low-cost holdings with very minimal effort.
