Hey everyone, Tony Leonardi, your Certified Financial Planner® professional from Newtown, Connecticut, back with another episode of *A Smarter Way to Retire*, because there really **IS** a Smarter Way to Retire.
Today we're tackling one of the foundational concepts in investing — one that most people may have heard of but few really understand: Modern Portfolio Theory, the Efficient Frontier, and the groundbreaking work of Harry Markowitz and William Sharpe.
By the end of this post, you'll know exactly what these ideas mean, why they won Nobel Prizes, and most importantly, how to use them to build a smarter, more efficient portfolio that can help your money work harder with less risk — potentially improving your retirement's probability of success. And isn't that what we're all here for? To improve your probability of success.
So how does that sound? Diversification is an important word, and it really means more than simply "don't put all of your eggs in one basket." That's a nice place to start, but diversification is actually Nobel Prize-winning math that can make your money work harder with less risk. If you've ever wondered how, this is the post for you.
A Real $1.5 Million Portfolio Wake-Up Call
Let me start with a story about a client we'll call Robert — 64 years old, came to me with a $1.5 million retirement portfolio. He wanted to retire in about a year and was very proud of his portfolio. He said, "Tony, I've got a mix of stocks, bonds, real estate. I'm well diversified."
Well, we ran his numbers through our portfolio analyzer and found that his long-term expected return was 6.5 % — pretty good. But his risk, or standard deviation, was 18 %. That means big swings, big stress in his portfolio, a lot of volatility. And we already know that volatility is your number one enemy in retirement. Volatility was really crushing his probability of success.
So then we rebuilt his portfolio using Modern Portfolio Theory principles. The same 6.5 % expected return, but his risk dropped from 18 % to 12 %. That's 33 % less volatility for the same growth. Robert said, "How is that even possible?"
Well, that's the magic of the Efficient Frontier — and that's what we're going to break down today.
What Is Modern Portfolio Theory?
Modern Portfolio Theory is the brainchild of Harry Markowitz. He won the Nobel Prize in Economics in 1990 for this.
The core idea: Investors can build portfolios that maximize return for any given level of risk or minimize risk for a given return. Let me repeat that: You can maximize return for the amount of risk that you choose to take or minimize risk for the return that you need.
It's not about picking hot stocks. It's about how assets work together. Some assets zig while others zag. Correlation. Markowitz showed that diversification isn't random. It's actually mathematical. By combining assets with low or negative correlation — for example, stocks and bonds — you can smooth out your ride without sacrificing growth.
Then William Sharpe built on this with something called the Sharpe Ratio, which is a way to measure risk-adjusted return. And that's the key: risk-adjusted return, not just return.
The Sharpe Ratio formula is actually your portfolio's return minus a risk-free rate divided by standard deviation.
Don't worry, you don't have to memorize the formula. I'm not going to quiz you on this after class. The important thing is to remember a higher number equals better efficiency or more return per unit of risk. Sharpe also won the Nobel Prize for his theory, the Sharpe Ratio. So Modern Portfolio Theory, putting Markowitz and Sharpe together, isn't theory — it's actually proven math.
The Efficient Frontier Explained
So if you look at the Efficient Frontier on a graph, the X-axis or the horizontal axis is risk or standard deviation — the more you move to the right, the more risk you're taking in your portfolio. The Y-axis is expected return — obviously higher up the axis, higher expected return. The Efficient Frontier is the curve on that line of portfolios that gives you the highest return for each given level of risk. Anything below that line is inefficient.
You're taking on too much risk for too little return. Anything above the line would be amazing, but it's not possible in the real world. The line is optimal. For example, all bonds would be low risk, low return. You'd be down in the lower left-hand corner of the chart. All stocks, higher risk, higher return, upper right-hand corner.
An efficient mix — 60/40 stocks/bonds or 70/30 — would be somewhere in the middle and on the line, which would be efficient, giving you the best bang for your buck. The goal is to get your portfolio on or as close to the Efficient Frontier line as possible.
I can tell you that I've analyzed hundreds of portfolios over the years of prospective clients and I've never seen one on the line. I've never seen an efficient portfolio, especially among do-it-yourself investors. There's almost always room for improvement, often a lot of room for improvement.
For those watching on YouTube, I'm going to show you a real-life client of mine who we started doing some planning for last year. He's a do-it-yourself investor and he has a nice $6.5 million portfolio. For those listening, just imagine this chart.
Long-term expected return for his portfolio: 5.48 % and risk or standard deviation: 9.2 %. You can see that he is way outside of his stated ideal risk band. He claims to be conservative, but he's taking on much more risk than he thought because no one has ever measured risk for him.
And being so far below the line, his expected return for this level of risk is super inefficient. We can literally move this portfolio over by 2 or 3 risk bands, almost cutting his risk in half, getting him into the risk band that he would be most comfortable with, without sacrificing a return.
That's the power of the Efficient Frontier. Now keep in mind that this is all on paper, it's all theory. The trick is how do you put this into action?
How to Build an Efficient Portfolio: The 5-Step Playbook
Here's the five-step playbook that we use with every client.
- Define Your Risk
This is based on your age, your goals, your sleep-at-night factor. There are several different questionnaires that we can use to help quantify your risk tolerance. And that's important. We want to quantify it. We want to put a number to it.
- Choose Asset Classes
Stocks, bonds, real estate, alternatives. We actually use 12 to 15 different asset classes to build these efficient recipes. Remember my analogy from last week: Building an efficient portfolio is like making a great meal or baking a great cake. You have to have all of the essential ingredients, and you have to have them in the correct amounts.
I see too many portfolios out there that are made up of one cup of sugar, one cup of flour, one cup of cinnamon, one cup of salt, one cup of milk. You get the point. Are they diversified? Yeah, they're diversified, but are they efficient? No, not at all, not even close.
- Allocate Based on Frontier Modeling
We use tools like our real-time analyzer to test different combinations and we aim for a total Sharpe Ratio of 1 or better. We give you the actual recipe to help you build a delicious portfolio.
- Diversify Within Classes
Part of building a good portfolio is diversification within classes, not just stocks and bonds, but U.S., international, large cap, small and mid cap, growth and value, etc.
- Rebalance or Reformulate Annually
Sell winners, buy laggers, add a little spice to help keep you on the Efficient Frontier because that frontier will change and your portfolio will change over time. You want to keep it up to date.
Here's a real result: One couple's inefficient 70/30 portfolio when they came to see us with a Sharpe Ratio of 0.8.
We turned it into an efficient portfolio with a Sharpe Ratio of 1.2 with a few tweaks. Same return, 25 % less risk. And remember, we want to reduce risk. We want to reduce volatility in retirement. Our ultimate goal is to help you realize a high probability of retirement success by building efficient portfolios.
So would you like to know if your portfolio is efficient or inefficient? If your portfolio hasn't been Efficient Frontier tested in the last year, now's the time.
