Investment Factors That Figure in Your Evidence-Based Portfolio

Evidence-Based Investment Insights: Factors That Figure Into Your Evidence-Based Portfolio

In our last piece, “The Essence of Evidence-Based Investing,” we explored what we mean by evidence-based investing. Grounding your investment strategy in rational methodology strengthens your ability to stay on course toward your financial goals, as we:

  • Assess existing factors’ capacity to offer expected returns and diversification benefits.
  • Understand why such factors exist, so we can most effectively apply them.
  • Explore additional factors that may complement our structured approach.

Assessing The Historical Evidence

An accumulation of studies dating back to the 1950s through today has identified three stock market factors that have formed the backbone for evidence-based portfolio builds over time:

  • The equity premium: Stocks (equities) have returned more than bonds (fixed income), as we described in The Business of Investing.”
  • The small-cap premium: Small-company stocks have returned more than large-company stocks.
  • The value premium: Value companies (with lower ratios between their stock price and various business metrics such as company earnings, sales and/or cash flow) have returned more than growth companies (with higher such ratios). These are stocks that, based on the empirical evidence, appear to be either undervalued or more fairly valued by the market, compared with their growth stock counterparts.

This is the trio of factors described in the Fama-French Three-Factor Model we discussed in The Essence of Evidence-Based Investing.” Similarly, academic inquiry has identified two primary factors driving fixed income (bond) returns:

  • Term premium: Bonds with distant maturities or due dates have returned more than bonds that come due quickly.
  • Credit premium: Bonds with lower credit ratings (such as “junk” bonds) have returned more than bonds with higher credit ratings (such as U.S. treasury bonds).

Understanding The Evidence

Scholars and practitioners alike strive to determine not only that various return factors exist, but why they exist. This helps us determine whether a factor is likely to persist (so we can build it into a long-term portfolio) or is more likely to disappear upon discovery.

Explanations for why persistent factors linger usually fall into two broad categories: risk-related and/or behavioral.

A Tale Of Risks And Expected Rewards

Persistent premium returns are often explained by accepting market-related risks that cannot be diversified away, in exchange for pursuing their expected rewards.

For example, it is presumed that value stocks are inherently riskier than growth stocks, relative to their underlying worth.

In “Value Premium Lives!” financial author Larry Swedroe explains:

“Among the risk-based explanations for the [value] premium are that value stocks contain a distress (default) factor, have more irreversible capital, have higher volatility of earnings and dividends, are much riskier than growth stocks in bad economic times, have higher uncertainty of cash flow, and … are more sensitive to bad economic news.”

Or, as Fortunes & Frictions financial blog author and advisor Rubin Miller describes:

“The ‘value’ is the price investors must pay for the company… Investors require lower prices to be willing to buy Turkish stocks over U.S. stocks, just as a consumer might require a lower price for buying a taco versus a pizza. The price has to clear for the purchase, and so it reflects value.”

A Tale Of Behavioral Instincts

When it comes to price-setting, there are also behavioral foibles at play. That is, our basic survival instincts often play against thoughtful reason. As such, the market may favor those who avoid acting on damaging gut reactions to breaking news.

Once we complete our exploration of market return factors, we will explore the fascinating field of behavioral finance. Suffice it to say for now, this “human factor” can contribute significantly to your ultimate success or failure as an evidence-based investor.

Your Take-Home

Factors that figure into market returns may be a result of taking on added risk, avoiding the self-inflicted wounds of behavioral biases, or a mix of both. Regardless, existing and unfolding academic inquiry on market return factors continues to hone our strategies for most effectively capturing expected returns according to your personal goals. The same inquiry continues to identify other promising factors that may augment our efforts. We will turn to those in the next installment of this series.
