How does one define “quality?” It is a question that we have sought to answer over the years in terms of a quality-oriented investment process and investing in what we consider “quality” stocks. We believe the most common quantitative measurement tends to be a company’s return on equity and how it stacks up relative to other businesses in the stock market.
Another characteristic that we believe describes “quality” is stability—stability in earnings, earnings growth, and stock price movement in general. Why do entities such as Standard and Poor’s and the rating agencies that use quantitative measurements of quality incorporate stability? For companies exhibiting high profitability, we believe it can be crucial to identify if this profitability is temporary and fleeting or if it is consistent and reliable, demonstrating a durable source of returns on capital. Assessing stability may weed out those companies that could be structurally unsound or subject to adverse changes under stress. In many ways, stability of a company’s balance sheet and predictability of earnings may provide resiliency in market downturns and protect capital.
Last year we noted the vigorous year for beta, or risk, in terms of stock performance. We also thought it was a challenging year for stability, notably in the fourth quarter. In the charts on this page, we look at stability from two sources—both measure the market volatility of stocks. The top chart measures 4Q25 performance with just the difference in the top and bottom quintiles of familiar characteristics, with low volatility experiencing stronger results. The chart below shows the absolute return difference between S&P 500 Low Volatility Index against the Russell 1000® Value Index.
We observed that the nature of market volatility tends to be tightly aligned with the stability of a company’s earnings growth. Companies that historically have exhibited more stable earnings growth and results tend to have less volatile stock market moves. The chart on this page summarizes Ned Davis Research data and shows how the EPS/stability characteristic performed last quarter versus how it has performed over the long term. Despite impressive long-term performance from stocks that have historically demonstrated stable earnings growth, last quarter was a challenge, in our opinion. We believe assessing the performance of characteristics over decades rather than quarters provides perspective on durable characteristics that may add value for the long haul.
