In today’s dynamic financial landscape, momentum investing offers investors a disciplined framework to capitalize on persistent market trends while managing abrupt reversals.
Backed by decades of robust research across equities, bonds, currencies, commodities and managed futures, momentum strategies have proven their merit in multiple regimes.
At its core, momentum describes the tendency for assets that have recently outperformed to continue outperforming over an intermediate horizon, while recent losers tend to remain weak.
This is not simply “buy what is going up.” A truly disciplined investment framework specifies the investment universe, lookback and holding periods, ranking methodology, position sizing, rebalancing rules, exit criteria, and risk controls.
Each approach offers unique advantages and can be combined to enhance robustness.
The seminal study by Jegadeesh and Titman (1993) documented that equities with strong recent performance tended to outperform recent losers over subsequent intermediate periods.
Since then, more than 30 years of research have confirmed the effect across developed and emerging markets, corporate bonds, commodity futures and even cryptocurrencies.
Carhart’s 1997 work on mutual funds found a momentum premium of approximately 0.67% monthly by going long last year’s top performers and shorting the laggards.
A broad study covering 1965 to 2009 across equities, commodities, currencies and bond futures reported statistically significant positive predictability of next-month returns based on past 12-month performance, with t-statistics above 5.
Several competing explanations help us understand why momentum persists:
Behavioral biases can delay full price adjustment. Underreaction to news, gradual herding, the disposition effect and attention-driven flows can reinforce trends over time.
Risk-based theories suggest that momentum returns compensate investors for bearing systematic stresses that are difficult to measure, such as liquidity risk, crowded trades, sudden correlation spikes and regime shifts.
In truth, momentum likely reflects a combination of behavioral inefficiencies and compensation for bearing hidden risks.
A systematic approach follows a clear workflow, turning academic insight into investable rules.
A practical rule might weight positions by signal divided by volatility and then scale to a target risk level, ensuring consistency with your overall risk budget.
Relative momentum and trend following share a foundation but differ in application and risk characteristics. They can be fused for enhanced diversification and robust signals.
By mid-2026, research from J.P. Morgan and Morningstar confirmed that momentum remained the strongest global equity factor in Q2, extending its best multi-year run since the dot-com era.
Russell Investments reported a 5.53% gain for its global large-cap momentum portfolio and 4.47% for its growth portfolio in that quarter, positive in five of six regions.
Yet analysts warned of heightened risk as crowded positioning and macro shifts can trigger sharp reversals. In March, macro momentum turned neutral amid rising geopolitical tensions before recovering later in Q2.
To harness momentum effectively, investors should:
• Establish clear risk limits and stress-test strategies against abrupt regime changes.
• Factor in realistic transaction costs and slippage when setting turnover targets.
• Diversify across asset classes to reduce reliance on any single trend.
• Combine relative and absolute filters to avoid holding assets that lose their own internal trend.
Ultimately, mastering momentum means balancing the power of persistent market trends with robust controls that protect capital during inevitable drawdowns.
By adhering to systematic rules, embracing academic insights, and staying vigilant to changing conditions, investors can ride the waves of momentum with confidence and discipline.
