The 2024 financial markets presented a complex landscape for investors. Amidst fluctuating interest rates, persistent inflation, and geopolitical uncertainties, US equities, particularly momentum stocks, emerged as a beacon of strong returns. However, this remarkable performance raises questions about sustainability and potential risks moving forward.

A year marked by a volatile Federal Reserve and stubborn inflation created challenges across various asset classes. Long-dated Treasury bonds experienced significant swings, commodities fluctuated with the ebb and flow of Chinese stimulus expectations, and even safe haven credit investments faced headwinds. US equities, and specifically large-cap technology stocks, provided a stark contrast, delivering substantial gains.
However, this success was far from evenly distributed. Value and small-cap stocks lagged behind, highlighting a significant divergence within the market. The S&P 500’s impressive 25% return masked a much more modest average gain for its individual components. Furthermore, recent weeks have witnessed a sharp pullback in momentum stocks, signaling a potential shift in market dynamics.
The Momentum Phenomenon: Riding the Wave of Winners
Momentum investing, a strategy that capitalizes on prevailing market trends by investing in recent winners, achieved record-breaking results in 2024. A dedicated momentum index tracked by S&P Dow Jones soared by 31%, its best performance since 2002. This remarkable outcome is attributed to several factors.
Big Tech names like Nvidia Corp. and Meta Platforms Inc. consistently led the market, driving the momentum surge. This concentrated performance benefited index fund investors but also amplified concerns about market concentration and potential vulnerabilities. Concurrently, momentum strategies successfully incorporated cyclical stocks that rallied following the US presidential election.
This exceptional performance has sparked debate about whether momentum investing has become self-fulfilling, particularly given the increasing influence of passive investment strategies. The tendency for investors to “let their winners run” has contributed to a sustained upward trend, even as fewer stocks surpass their 200-day moving average, a potential indicator of market breadth weakness.
Beyond Equities: Momentum and Value in Credit Markets
The momentum effect extended beyond equities, influencing credit markets as well. Investing in bonds issued by companies with strong stock momentum proved profitable. However, in a generally risk-on environment, the value factor, focusing on bonds with wider spreads, ultimately outperformed. This contrasts with the equity market, where value stocks underperformed and momentum gains further inflated the relative valuations of winning stocks.
Sustainability Concerns: Valuations and Potential Volatility
The substantial gains in momentum stocks have raised concerns about stretched valuations and the potential for increased volatility. The widening gap between the price-earnings ratios of high and low momentum stocks suggests limited room for further significant momentum gains. Recent market fluctuations reinforce these concerns, as momentum stocks experienced a sharp decline while the broader market consolidated its gains.
The Tech Factor: Resilience and the AI Narrative
The resilience of the technology sector, fueled by the artificial intelligence boom, underpins much of momentum’s success. Even a potential economic downturn might not significantly impact tech companies, given their robust earnings and strong balance sheets. This sector-specific strength contributes to the persistence of momentum trends, but also raises questions about the market’s dependence on a single sector.
Looking Ahead: Navigating Uncertainty and Potential Reversals
While momentum investing delivered exceptional returns in 2024, investors must carefully consider the sustainability of this trend. Stretched valuations, increasing market concentration, and the potential for sudden reversals warrant caution. The interplay between momentum and value, both within and across asset classes, will likely shape market dynamics in the coming year. The reliance on technology sector strength and the evolving AI narrative will also play a crucial role in determining the future trajectory of momentum investing. As we move into 2025, navigating these complexities will be essential for successful investment strategies.
