Momentum ETFs **SPMO**, **MTUM** Experience Strong Monthly Performance
Tue Apr 28 2026
Momentum ETFs such as **SPMO** and **MTUM** are demonstrating significant outperformance this month, bouncing back after a period of lagging returns.
According to ETFTrends, momentum as an investment factor has shown significant resurgence this month, reversing its earlier underperformance in the first quarter. Specifically, the underlying index for the Invesco S&P 500 Momentum ETF (SPMO) is experiencing its most favorable monthly performance since its inception in November 2014. This strong showing highlights a renewed interest and positive trajectory for momentum-focused strategies in the current market environment.
What Happened
After a subdued start to the year, the momentum factor has staged a notable comeback in the current month. The report from ETFTrends on April 24 indicated that the underlying index of SPMO is recording its best monthly return since its launch almost a decade ago. This signifies a material shift in market dynamics, where stocks that have demonstrated strong recent performance are continuing to outperform, a key characteristic of momentum strategies.
Why It Matters for ETF Investors
For ETF investors, the renewed strength in momentum ETFs like SPMO and the iShares MSCI USA Momentum Factor ETF (MTUM) is particularly relevant. Momentum strategies aim to capitalize on the tendency of assets that have performed well in the recent past to continue performing well in the near future. While this factor can be cyclical and experienced a dip earlier in the year, its current outperformance suggests a potential change in market leadership or a rotation into growth-oriented and trending assets. Investors utilizing factor-based strategies, or those looking for exposure to market leadership, will find this development significant. The bounce back could signal a period where high-performing stocks continue their upward trajectory, offering opportunities for those invested in or considering momentum-focused ETFs.
Affected ETFs
Several ETFs are directly poised to benefit from or are currently reflecting this momentum resurgence:
SPMO (Invesco S&P 500® Momentum ETF): This ETF tracks the S&P 500 Momentum Index, focusing on S&P 500 constituents with the highest momentum scores. Its underlying index's strong monthly performance makes SPMO a direct beneficiary of the current momentum factor outperformance.
MTUM (iShares MSCI USA Momentum Factor ETF): This ETF seeks to track the investment results of an index composed of U.S. equities with high momentum characteristics. As a prominent momentum-focused ETF, MTUM is similarly positioned to capture the benefits of this factor's renewed strength.
Sector / Classification Impact
The revitalization of the momentum factor primarily impacts the "Size and Style" category within equity asset classes. Momentum is a key investment "strategy" or "factor" that cuts across traditional sectors, identifying stocks with strong recent price trends regardless of their industry. Therefore, while no single sector is exclusively impacted, the resurgence of momentum suggests that stocks exhibiting strong positive trends, which could span various sectors, are currently favored. This scenario often benefits growth-oriented segments of the market or sectors experiencing strong tailwinds, impacting the broader "equity" asset class.
Bottom Line
The significant rebound in momentum ETFs, exemplified by the strong performance of SPMO and MTUM, signals a potentially important shift in market dynamics. After a period of underperformance in Q1, the momentum factor is demonstrating robust returns, indicating that stocks with established trends are regaining their leadership. ETF investors focused on factor-based strategies should closely monitor this development as it could influence portfolio allocations and performance in the coming months.
