It’s Time for a Venial Value-Timing Sin
November 7, 2019
Cliff discusses how to measure whether a factor, in this case the value factor, is itself rich or cheap versus history. The answer, regardless of the approach taken in measuring cheapness, is that value is currently quite cheap compared to history.

How Do Factor Premia Vary Over Time? A Century of Evidence
July 2, 2019
We examine four prominent factor premia – value, momentum, carry, and defensive – over a century from six asset classes. The results offer support for time-varying risk premia models with important implications for theory seeking to explain the sources of factor returns.

The Siren Song of Factor Timing, aka “Smart Beta Timing,” aka “Style Timing”
June 1, 2016
Often the first question after an initial discussion of factors is “Okay, what’s the current outlook?” And the common answer, “The same as usual,” is often unsatisfying.

Is (Systematic) Value Investing Dead?
May 8, 2020
When value has underperformed for so long, it’s natural and proper that people wonder if it’s ever going to work again. To test the popular explanations for why value investing is “broken,” Cliff tweaks the value factor’s construction to remove the stocks that best fit these stories. He finds no “this time is different” explanation holds water, affirming our belief that the medium-term odds are rather dramatically on value’s side.

The Valuesburg Address
February 27, 2020
One score and eight years ago Fama and French brought forth on this world, a new factor, conceived in either risk or behavioral effects, and dedicated to the proposition that all portfolios are not created equal. Now we are engaged in a great drawdown, testing whether investors in that factor, or any factor so conceived and so dedicated, can long endure…

Never Has a Venial Sin Been Punished This Quickly and Violently!
February 19, 2020
Three months ago in “It’s Time for a Venial Value-Timing Sin,” Cliff demonstrated the value factor’s historic cheapness, suggesting it’s time to “sin a little” and modestly overweight value. While portfolio tilts are seldom promptly rewarded, it’s also rare they are instantly punished. In this piece, Cliff shows how 2020 has been the exception to the rule, as value has begun this year with its worst loss in its decade-long drawdown.
