Momentum Ruled In 2024, But Reversal Likely In 2025

The investment landscape in 2024 has been dominated by an exceptional momentum run, marking one of the most significant performances in the past three decades. Historically, such strong momentum tends to reverse in the following year, suggesting potential challenges for momentum stocks in 2025. Despite this historical trend, the current middling valuations of momentum stocks could mitigate the extent of any negative reversal.

Momentum stocks, defined by their high 12-month risk-adjusted returns, have significantly outperformed their low momentum counterparts by 28% year-on-year as of December 11th, a rare two standard-deviation event. This performance has outpaced other factors, including high growth and quality stocks, which have also seen gains but not to the same extent.

The historical pattern indicates that extreme performance, like that observed in 2024, often leads to poor future returns for high momentum stocks, particularly over a 6-12 month outlook. As such, the odds are currently 2-1 against momentum stocks for 2025, suggesting that financial advisors and portfolio managers should approach these assets with caution.

In summary, while 2024's momentum run presents an impressive narrative, the potential for a reversal in 2025 requires careful consideration and risk management to navigate the possible downturn in momentum stock performance.
