Momentum investing has gained traction as a powerful tool for capturing upside in post-recessionary bull markets, and the iShares MSCI USA Momentum Factor ETF (MTUM) exemplifies this approach. 

Designed to overweight stocks with strong recent performance, MTUM delivered a 1,030% total return from 2009 to 2025, recovering quickly from drawdowns and outperforming broader market indices. Its risk-adjusted returns, reflected in a Sharpe ratio of 0.68 and Sortino ratio of 0.90, show that it balances volatility with consistent performance, particularly when tilted toward high-growth sectors like tech. 

Academic research backs this strategy, highlighting its resilience and efficiency during economic recoveries, especially when managed with volatility controls. While MTUM carries market risk, its focus on large and mid-cap stocks helps mitigate exposure to smaller, more volatile names. 

Finsum: For long-term investors willing to ride short-term swings, MTUM presents a disciplined way to harness the enduring power of momentum.
