Size, momentum, volatility and value have all been shown to be partly responsible for explaining equity returns over the long run but they do not seem to fully capture the returns of some companies. This has therefore given credence to the idea that a fifth factor – quality – exists and, when combined with other risk factors, acts as a good diversifier in investment portfolios.

What is Quality?

There isn’t much agreement on what ‘quality’ is or how it should be measured. Some simply equate it to profitability and others, believing it to be a multi-faceted concept, use more complex measures (e.g. the Piotroski’s F score). Regardless of the approach taken, the aim of any quality measure should help estimate a company’s future profitability and understand its source of risk. Broadly speaking, high-quality companies should generate higher revenue and enjoy more stable growth than the average company. This is why we believe that any good quality measure should take into account profitability generation, earnings quality and financial robustness.

How Does Its Performance Stack Up?

Quality strategies broadly outperformed their benchmarks, both on an absolute and risk-adjusted basis. Among all the regions we examined, the out-performance was highest in the US. In addition, quality strategies held up well in bear markets and although their performance lagged in bull markets, they nonetheless participated in bull market rallies (such as 2003 and 2004).

In What Macroeconomic Environment Does It Do Well?

Quality stocks are sensitive to economic growth and tend to deliver higher excess return when the economy slows. That said, their attractiveness diminishes when the economy experiences above-trend growth, although they still deliver positive excess returns. In comparison with the S&P 500, S&P 500 Quality is exposed to industrial production and the narrowing of credit spreads. However, the quality index does not have any significant tilt towards oil prices, inflation, housing starts or the slope of the yield curve.
