The Science of Portfolio Strategy
Your investment portfolio is the engine of your financial journey—it helps move you down the path towards your long-term goals. Each piece plays an important role in reaching the outcomes you desire.
Whether you need help growing your wealth or protecting it, we design your portfolio so that each investment has unique characteristics and will react differently to economic, political and societal influences. This is part of the diversification process, and it’s one way we use science over guesswork when designing your portfolio.
The Pillars of Evidence-Driven Investing™
We design portfolios to help you achieve your financial goals. We don’t believe in trying to time the market, anticipate trends or identify mispriced investments. These techniques have been shown to be a highly unreliable way to build wealth.
Backed by over 70 years of research, we use an approach rooted in smart diversification, low costs and tax-aware investments. We call this unwavering commitment and our approach to the data and research that drives everything we do, Evidence-Driven Investing™.
Our Evidence-Driven Investing™ Portfolios Are Built on Five Pillars
Markets Are Highly Efficient
Billions of dollars are traded daily where buyers and sellers come together and agree on a price. Given so much competition, we believe the current price reflects both the latest news and the latest outlook for the investment and the economy. That’s why we say the price is the best estimate of the current value, and we don’t try to outsmart the market.
Risk & Expected Reward Are Related
If you want the potential for more return, you’ll need to accept more risk and likely greater fluctuations in value. Sometimes these risks pay off with more return, but sometimes they result in losses. Although adding more unique sources of risk and return can create a portfolio with steadier growth, we don’t believe in taking more risk than you’re comfortable with.
Diversification Is Essential
Diversification has been called the only free lunch in investing. This is because using a single stock, strategy or investment type is riskier than mixing lots of different types of investments. Holding multiple investments reduces the risk that any single investment will cause a drag on portfolio performance.
Pursue Factors Of Returns
Science has shown us that allocating more of your portfolio to companies that share certain characteristics can increase your potential for return. Although these investments typically bring more risk, our portfolios are built to most efficiently allocate across multiple sources of risk—even if it means performing differently than headline indexes.
Focus On What We Can Control
We don’t try to predict interest rates, anticipate the impact of government actions or outsmart other traders. Instead, we focus on the areas within our control—such as setting a thoughtful investment strategy and following a disciplined review process.
Your Portfolio Building Blocks
We use this approach across all different types of investments. Although we can’t predict where markets will go, we feel that it’s highly unlikely anyone else can either. Instead, we focus on building a portfolio that increases the probability that your plan will be successful.
Each part of your portfolio, whether stocks, bonds or alternatives, plays a unique role in the risk and return profile of your portfolio. When combined, they create a path towards achieving your personal financial goals.
Stocks
Investing in companies can increase the growth potential of your overall portfolio. We believe any prudent stock portfolio should be invested in companies, both big and small, all around the world.
Bonds
High-quality bonds are the bedrock of your portfolio and can preserve what you’ve worked hard to achieve. A reasonable allocation to high-quality bonds can help reduce the amount you lose in market downturns and help you recover faster.
Alternatives
Alternatives can be used to improve overall portfolio results. These assets can cushion the portfolio from declines in stock markets while offering greater chance for portfolio growth compared to bonds.
An Evidence-Driven Investing™ Approach
While most professionally designed portfolios will use a combination of stocks and bonds, Buckingham uses financial science to look beyond asset classes to better understand both the risks that drive performance and how to effectively capture those risks. This is done with the goal of providing true diversification to help improve your investment journey.
Your portfolio is different in these ways:
- Uses decades of research to understand the risks that drive returns within each asset class
- Captures returns more effectively given your tolerance for different types of risk
- Strategically blends your investments and tilts toward higher returning assets
- Balances stock risks with only the highest-quality bonds
The Benefits of Portfolio Tilts
Stocks | Bonds | Alternatives | Portfolio
Tilt Stocks To Improve Your Outcome
We use stocks to grow the portfolio. Every portfolio we design starts by investing in companies around the globe. The result is a portfolio that can include more than 8,000 companies across more than 45 countries.
In addition, research has shown that investing more in companies that share certain characteristics, such as being smaller, of higher quality and less expensive, can change the risks of your portfolio, also increasing your potential for higher returns.
We call this tilting the portfolio – a method of potentially improving the performance of your stock portfolio.
Curious which types of companies tend to have better returns over time?

Key Factors in Your Evidence-Driven Portfolio
Academics and professional investors have documented over 400 factors that can improve your portfolio. Only a certain subset, however, are backed by data and evidence. In order to be considered, we believe each factor should be intuitive, persistent, pervasive, robust and cost-effective.
By strategically overweighting certain companies and underweighting others, we can improve the growth potential of your stock allocation. We tilt to the following types of companies to provide a better opportunity for returns:
- Smaller: Companies which have a lower value, or market cap, tend to generate better stock returns, on average, than larger companies. We call this the Size premium.
- Less Expensive: Companies which trade at a lower price relative to their earnings, book value or cash flow tend to generate better stock returns, on average, than their more expensive counterparts. We call this the Value premium.
- Better Financials: Companies with more consistent earnings, stronger profit margins and less debt tend to generate better stock returns, on average, than their weaker counterparts. We call this the Quality premium.
In other words: quality companies trading at good prices with plenty of room to grow tend to perform better than other companies.

Pinpoint Bonds that Offset Stock Market Risk
The main purpose of bonds is to protect the wealth you’ve worked hard to accumulate. We achieve this by focusing on only the most secure and creditworthy bonds, like those backed by the U.S. government. This is done to minimize the risk of default on your investment. Including bonds that will be repaid (or mature) within the next one to 10 years helps insulate the portfolio from the larger price swings that stocks often endure.
This protection becomes especially important as you start withdrawing from your portfolio. The impact of including high-quality bonds in your portfolio can be significant, leading to a smoother ride and providing the cushion your portfolio needs to endure through poor stock market performance.

Add Alternatives to Improve Your Portfolio
Alternatives are simply investments that have unique sets of risk compared to traditional stocks or bonds. Although we remain skeptical of most alternative strategies, a small collection of alternatives can offer truly unique sources of risk and return.
Adding alternatives can cushion the portfolio from stock market fluctuations while offering a greater chance for growth compared to high-quality bonds. Even a small allocation to alternatives can soften the portfolio from stock market declines—often giving you a smoother ride compared to a portfolio that is only allocated to stocks and bonds.

Designed for Better Outcomes
We know all investments will go through periods of decline, and our portfolios are no exception. We don’t chase the latest trend, try to keep up with an index or sell before the next decline. Instead, we design portfolios to let the power of the markets work for you.
By combining multiple sources of risk and return, tilting our stock portfolio to companies with a higher potential for future return and protecting your wealth with high quality bonds, we can increase the probability that you remain confident in the success of your financial goals.
Above Confidence Zone
Disclosure
A Probability of Success is based on a Monte Carlo Simulation. The projections or other information regarding the likelihood of various investment outcomes are hypothetical in nature, do not reflect actual investment results, and are not guarantees of future results. Monte Carlo simulations are used to show how variations in rates of return each year can affect your plan results. A plan includes information about your assets, financial goals, and personal situation, as well as assumptions regarding the projected inflation rate and the projected return and volatility for various asset classes. A Monte Carlo simulation calculates the probability of success of a plan by running it many times, each time using a different sequence of returns. Some sequences of returns will give you better results, and some will give you worse results. These multiple trials provide a range of possible results, some successful (you would have met all your goals) and some unsuccessful (you would not have met all your goals). The Probability of Success is the percentage of trials where your Plan, with all its underlying assumptions, had at least $1 remaining in the financial accounts at the conclusion of the analysis. Analogously, the percentage of trials that were unsuccessful is the Probability of Failure. No portfolio allocation eliminates risk or guarantees investment results.
