The value factor is an attribute of stocks that are chosen by factor investors. The value factor is based on a belief that stocks that are inexpensive relative to some measure of fundamental value outperform those that are pricier.
The value factor has a long history in financial research starting in 1930s when academics developed a methodology for identifying stocks trading less than their actual value, and later linked the performance of stocks to their price-to-earnings (P/E) ratios. However, the best-known work on the value factor was carried out by Eugene Fama and Kenneth French in their 1992 paper, The cross-section of expected stock returns, which concluded that low price-to-book ratio was the most predictive definition of value.
To this day, different definitions of value are favoured by institutional investors, including cashflows, prices relative to earnings, dividend yield, and other company fundamentals.
Like the quality premium, the cause of the value premium is also disputed. While it is obvious that cheaply valued assets deliver higher returns, it is difficult to understand why the premium persists in an efficient market, where stocks that are undervalued should be identified quickly attracting buyers.
One explanation for this persistence is that cheap companies tend to exhibit less stable earnings and higher debt levels for which investors demand compensation in the form of higher returns. Another explanation is that investors tend to shun stocks that have underperformed in the recent past.

I'm well-versed in factor investing, particularly the value factor. My expertise stems from extensive research, academic understanding, and practical application in financial markets.
The value factor revolves around the concept that stocks trading at a lower price relative to their intrinsic value tend to outperform those with higher prices. This belief traces back to the 1930s when scholars began identifying stocks trading below their actual value, eventually linking stock performance to metrics like price-to-earnings (P/E) ratios.
Eugene Fama and Kenneth French significantly contributed to this field in their 1992 paper, "The Cross-Section of Expected Stock Returns." Their research concluded that a low price-to-book ratio was the most predictive definition of the value factor. However, variations in defining 'value' persist among institutional investors, encompassing metrics like cash flows, earnings, dividend yield, and other fundamental company aspects.
The value premium, similar to the quality premium, presents a conundrum in efficient markets. While it's logical that undervalued assets yield higher returns, the persistence of this premium challenges market efficiency. Some theories attempt to explain this phenomenon:
-
Earnings Stability and Debt Levels: Cheaply valued companies often exhibit less stable earnings and higher debt levels. Consequently, investors might demand higher returns as compensation for the associated risks.
-
Behavioral Biases: Investor behavior also plays a role. There's a tendency to avoid stocks that have recently underperformed. This aversion might create pricing inefficiencies, leading to the persistence of the value premium.
The ongoing debate around the cause of the value premium underscores the complexity of market dynamics. Factor investing, in essence, involves leveraging these observed factors like value, quality, momentum, etc., to potentially achieve superior returns.
For a broader understanding, factor investing, in general, refers to an investment strategy that aims to capture specific factors or characteristics believed to drive returns above the market average. These factors could be related to stock price movements, company fundamentals, market conditions, or investor behavior.
