Momentum, a cornerstone of trading strategies, has long captivated financial scholars and practitioners for its consistent profitability.
However, a lingering challenge in its application is the occurrence of what is termed “momentum crashes,” abrupt and substantial downturns in the performance of the momentum strategy. This paper, titled “Momentum Crashes and the 52-Week High” by Suk-Joon Byun and Byounghyun Jeon, delves into the intricate dynamics of momentum crashes, unraveling a pivotal relationship with the proximity of stocks to their 52-week highs during market rebounds.
The significance of this study lies in its nuanced exploration of the reasons behind momentum crashes, a phenomenon not fully understood in the financial literature.
By scrutinizing the behavior of stocks concerning their 52-week highs, the research provides a comprehensive understanding of the drivers of momentum crashes. The implications of such insights are profound for investors and market participants, offering a strategic advantage in navigating the complexities of momentum strategies.
Let’s take a look at the methodology and the key findings of the study.

Methodology Used in The Study
The study employs a comprehensive methodology to uncover the nuances of momentum crashes and the influence of the 52-week high.
The primary variables of interest are the past 12-month returns (momentum) and the nearness to the 52-week high (near high). The research period spans from January 1926 to December 2015, covering various market conditions and allowing for a nuanced understanding of momentum behavior.
Key Findings of The Study
The central hypothesis revolves around the relationship between nearness to the 52-week high and subsequent returns, particularly during market rebounds.
The findings suggest a negative correlation; stocks far from their 52-week highs outperform those near their highs during market rebounds. This outperformance substantially contributes to the occurrence and magnitude of momentum crashes.
1. Momentum Crashes and 52-Week Highs Relationship
The study reveals a critical correlation between momentum crashes, defined as significant drops in momentum strategy profits, and the proximity of stocks to their 52-week highs.
Notably, during market rebounds, stocks that are farther from their peak values outperform those closer to their highs. This consistent pattern of outperformance during market recoveries significantly contributes to the occurrence of momentum crashes.
The phenomenon is not confined to a specific market but is observed across global markets, including Japan, the United Kingdom, and continental Europe, underlining its broad relevance.
2. Anchoring Bias and Momentum
Building on the anchoring bias concept, the research sheds light on how speculative investors anchor their valuations on 52-week highs.
This leads them to prefer stocks situated further from these highs, assuming they are undervalued with more room for price appreciation.
Consequently, this bias results in the overvaluation of stocks distant from their highs and subsequent negative returns during the holding period. The anchoring bias thus plays a crucial role in explaining the dynamics of momentum crashes.
3. Sentiment-Driven Mispricing
The findings support the sentiment-driven mispricing hypothesis, indicating that heightened investor sentiment during market rebounds translates into higher contemporaneous returns for stocks situated further from their peaks.
This aligns with previous research linking sentiment increase with elevated returns, particularly for speculative stocks.
Therefore, the research establishes a connection between changes in investor sentiment, speculative demand, and the subsequent performance of stocks in relation to their 52-week highs.
4. Nearhigh-Neutral Momentum Strategy
Addressing the challenges posed by momentum crashes, the paper introduces a novel approach—the nearhigh-neutral momentum strategy.
This strategy involves selecting past winners and losers based on their proximity to 52-week highs, effectively mitigating the crashes associated with conventional momentum strategies.
Notably, the nearhigh-neutral strategy achieves this without compromising profitability, presenting a more robust and stable alternative for investors seeking to capitalize on momentum effects.
5. Generalization to International Markets
The study extends its empirical findings to international equity markets, demonstrating the universality of negative momentum profits during market rebounds.
This consistent pattern is observed in markets such as Japan, the United Kingdom, and continental Europe.
Importantly, the nearhigh-neutral momentum strategy is not only effective in these international markets but also revitalizes momentum profits in Japan. This highlights the adaptability and robustness of the proposed strategy across diverse global contexts, making it a valuable insight for investors operating in different market environments.
This research sheds light on the intricate relationship between the proximity to 52-week highs, investor sentiment, and momentum crashes.
By introducing a nearhigh-neutral momentum strategy, the study provides a nuanced understanding of momentum dynamics, offering investors an alternative approach that maintains profitability while mitigating the downsides associated with conventional momentum strategies.
These insights are not only applicable to the U.S. market but also generalize to international equity markets, showcasing the universality of the sentiment-driven mispricing hypothesis.
Understanding the mechanisms that lead to momentum crashes is not merely an academic exercise; it holds tangible implications for risk management and portfolio optimization.
Investors armed with the knowledge from this study can tailor their investment strategies to mitigate the impact of momentum crashes, fostering more resilient and consistent returns. Moreover, the international extension of these findings reinforces their universality, making them applicable across diverse global markets.
