A Decade of Factor Underperformance Can Reverse in Months
Butler uses the late-1990s value drought to show why recent performance can give a misleading view of long-term factor returns. Growth dominated for most of a decade, yet a sharp reversal around the technology bust reportedly moved value ahead over the full ten-year period within roughly three months.
- Every factor can experience prolonged underperformance
- Value was widely dismissed near the end of the 1990s
- Factor reversals can occur too quickly to time reliably
- Recent winners may not remain long-term winners
“there's always gonna be moments in in periods of time where they don't actually outperform or have the premium that that we discussed earlier.”
“within a three month period, value over that whole tenure period actually had a better performancing.”
