Updated: Mar 23
FMTM and SPMO both offer exposure to U.S. momentum stocks, but they employ very different methodologies and produce very different results. This guide compares how each fund works, examines their track records, and discusses how each approach may fit in your portfolio. All data as of 2/28/2026. All performance data is based on the net asset value (NAV) unless otherwise noted.
Executive Summary
Same Goal, Different Implementation: FMTM and SPMO both target U.S. equity momentum, but their approaches differ significantly. FMTM employs an active, equal-weighted approach across large- and mid-caps with monthly rebalancing, while SPMO tracks a passive S&P 500 momentum index rebalanced semi-annually.
How Momentum Is Defined: The two funds use fundamentally different selection criteria. FMTM emphasizes 6-month trend consistency, whereas SPMO ranks stocks by 12-month returns, excluding the most recent month. This distinction shapes which stocks are selected and when positions shift, which ultimately impacts each fund’s responsiveness to trend changes.
Different Performance Results: Since FMTM's March 19, 2025 inception, methodology differences have resulted in substantial performance divergence. FMTM has returned +48.8% with a −9.2% maximum drawdown and a 28 day max drawdown period, compared to SPMO's +26.4% return with a −15.2% drawdown and a 87 day max drawdown period, a material gap that illustrates how methodology impacts performance outcomes.
Risk Management Varies: FMTM's monthly rebalancing allows it to respond faster during volatility spikes and trend changes, while SPMO's fixed semi-annual schedule adjusts more slowly in rapidly changing markets. The frequency of portfolio adjustments directly influences how each fund responds to changing markets.
Portfolio Role Depends on Investor Preference: FMTM may suit investors seeking a higher-conviction, actively managed momentum sleeve with a tighter risk management strategy, while SPMO may appeal to those prioritizing lower cost and a core passive factor exposure. The right choice hinges on existing portfolio structure and the role momentum is intended to fill.
How Each Fund Is Built
SPMO – Traditional Index-Based Momentum
SPMO tracks the S&P 500 Momentum Index, which selects the 100 stocks within the S&P 500 with the highest price performance over the trailing 12 months, excluding the most recent month. Holdings are weighted by a blend of market capitalization and momentum score. The approach is simple and low cost. It rebalances twice a year, which keeps turnover low, and since it only draws from the S&P 500, every stock in SPMO is a large-cap U.S. company. Sector constraints prevent extreme concentration in any one industry.
FMTM – Quantitative Momentum Built Around Trend Quality
FMTM takes a different approach to momentum. Rather than ranking stocks by trailing 12-month returns, the strategy seeks to identify companies exhibiting the most consistent, high-quality upward price trends today. The model uses a 6-month lookback window instead of the traditional 12-month lookback that most momentum ETFs use and evaluates not only total return but the consistency of price movement. Stocks that have advanced steadily over time score more favorably than those with sharp spikes followed by uneven or sideways movement.
The investable universe extends beyond the S&P 500 to include large- and mid-cap companies, allowing it to capture opportunities SPMO's narrower universe excludes. The portfolio typically holds 30 to 50 equal-weight positions updated monthly. Stocks with strong, stable momentum are retained, while those showing weakening trends are removed to capture profits and limit further losses. The monthly rebalance allows the strategy to adapt in real time as market conditions shift.
Historical Performance and Portfolio Drawdown
The table below summarizes performance and maximum drawdown across momentum ETFs since FMTM’s inception date on March 19, 2025. Implementation differences have produced a wide range of outcomes. FMTM’s quantitative strategy has delivered a +48.8% return compared to VFMO (+34.0%), XMMO (+29.0%), FDMO (+27.6%), SPMO (+26.4%), JMOM (+23.9%), and MTUM (+23.9%), while the S&P 500 (SPY) returned +21.0%.
Downside experience also varied across approaches. FMTM experienced a maximum drawdown of −9.2%, compared to drawdowns of S&P 500 (−13.7%), SPMO (−15.2%), MTUM (-14.3%), XMMO (−13.9%), JMOM (-13.7%), FDMO (14.8%), and VFMO (−16.2%).
Equally important as the portfolio's max drawdown is how long it takes the fund to recover and reach a new high. FMTM's maximum drawdown lasted 28 days from peak to trough to full recovery. By comparison, SPMO spent 87 days underwater at its worst. Every day a portfolio spends below its prior high is a day an investor is watching losses rather than capturing gains. A fund that falls less and recovers faster protects capital during volatile markets. Across a full market cycle, the difference can lead to meaningfully different total returns.
Despite sharing a common momentum objective, differences in portfolio construction, signal definition, and rebalance methodology have translated into materially different return and drawdown outcomes. The data reinforces an important concept: how momentum is implemented can meaningfully impacts both upside capture and drawdown risk.

The funds included in the comparison table were selected based on four criteria: (1) a momentum-based investment objective, defined as explicitly targeting the momentum factor as the primary strategy as stated in each fund's prospectus; (2) primary investment in U.S.-listed equity securities; (3) a continuous trading history covering the full comparison period; and (4) availability of publicly verifiable performance data. While we believe this comparison table represents the vast majority of the invested assets in U.S. momentum ETFs, this peer group is not exhaustive, and investors are encouraged to conduct their own research when evaluating the full universe of available products.
Side-by-Side Comparison of Key Characteristics
FMTM and SPMO both seek to capture U.S. equity momentum, but they differ meaningfully in structure and implementation. FMTM, launched in March 2025, is an actively managed quantitative ETF with a 0.45% expense ratio and assets of approximately $80 million. SPMO, launched in October 2015, is a passive index ETF with a 0.13% expense ratio and manages roughly $14 billion in assets.
Portfolio construction differs significantly. FMTM holds 30–50 U.S. large- and mid-cap stocks equal-weighted and rebalanced monthly. In contrast, SPMO owns approximately 100 companies selected exclusively from the S&P 500, weighted by market cap and momentum and updated twice a year.
The underlying momentum signals are distinct. FMTM emphasizes consistency and quality of price trends over a six-month lookback, while SPMO ranks stocks by 12-month total return, excluding the most recent month. Since FMTM's inception, these signal differences have produced distinct outcomes: FMTM returned +48.8% with a −9.2% maximum drawdown compared to SPMO's +26.4% return and −15.4% drawdown. The structural and methodological differences explain why two funds pursuing the same objective have delivered materially different portfolio characteristics and results.

Comparing SPMO vs FMTM’s Risk Management
The two ETFs manage risk very differently. FMTM's quantitative framework places greater emphasis on recent price data, allowing it to respond more quickly as market leadership shifts. By shortening its effective lookback during periods of stress and rebalancing monthly, the portfolio can rotate away from deteriorating trends toward areas demonstrating relative strength. This process is designed to help improve downside behavior during sharp market corrections rather than remaining anchored to stale momentum signals.
SPMO follows an index methodology with a fixed 12-month lookback and semi-annual rebalancing. This structure provides transparency and consistency, but portfolio adjustments occur only twice yearly. In rapidly changing markets, leadership can shift well before the next scheduled rebalance, potentially resulting in slower repositioning.
The difference in risk management can emerge during extended drawdowns, such as 2008 or 2022. FMTM's monthly rebalance and shorter lookback are designed to shift the portfolio toward relative strength, even as broad equity stress persists. Market corrections don’t make capital disappear—they redirect it. When market trends change and previous leaders come under pressure, capital typically rotates elsewhere. Leadership changes, which can present new opportunities. By updating monthly and emphasizing recent price behavior, FMTM aims to capture those shifts. SPMO, by contrast, remains more static between rebalances, potentially holding positions that have fallen out of favor.
Common FAQs
1. Tax Efficiency – Does FMTM's higher portfolio turnover impact the tax efficiency of the fund?
Monthly rebalancing does generate more portfolio turnover than semi-annual rebalancing. However, the ETF structure can help maintain tax efficiency and minimize tax consequences. The in-kind creation and redemption process allows appreciated securities to be transferred out of the portfolio without triggering taxable sales at the fund level, thereby minimizing taxable capital gains. This mechanism, which is standard across U.S. ETFs, allow the strategy to adjust holdings systematically while reducing the likelihood of capital gain distributions to shareholders. To date, FMTM has not made any capital gains distributions. All ETFs, including FMTM, cannot guarantee tax outcomes and investors may still receive taxable distributions. Investors should consult their own tax advisors regarding the tax consequences of an investment in the Fund.
2. Rebalance Timing – FMTM rebalances monthly, while SPMO rebalances every six months. Does this matter?
Yes, rebalance timing can meaningfully impact outcomes. A monthly rebalance allows FMTM to adjust more quickly as market leadership changes, potentially rotating away from weakening trends into emerging ones. In contrast, SPMO’s semi-annual schedule means portfolio changes occur only twice per year, which can result in slower repositioning during fast-moving or volatile environments. The trade-off is straightforward: more frequent rebalancing increases turnover, while less frequent rebalancing offers greater stability among holdings but with slower response times.
3. Risk Management – Why does a smaller portfolio drawdown matter so much?
Many investors focus primarily on returns, but drawdown—how much a portfolio declines before recovering— can be just as important. The deeper the decline, the harder it is to get back to even: a 15% loss requires a 17.6% gain to recover, while a 9% decline requires less than a 10% rebound. Smaller drawdowns can reduce recovery time and make it easier for investors to stay disciplined during periods of volatility. Since inception, FMTM’s maximum drawdown of −9.2% compares to SPMO’s −15.4% and the S&P 500’s −13.7%. Limiting peak-to-trough losses is a meaningful risk-management outcome.
4. Fund Size – FMTM only has around $80M in assets compared to SPMO's +$10 billion. Is that a red flag?
FMTM launched in 2025, while SPMO launched in 2015—a ten-year head start. Asset size is often a lagging indicator of fund quality, not a leading one. FMTM's $80 million in assets does not constrain its ability to execute the strategy. More importantly, FMTM has delivered meaningfully different results than larger momentum peers (+48.8% since inception versus +26.4% for SPMO). Performance, not fund size, should drive investment decisions.
5. Bid/Ask Spreads – Does FMTM's smaller AUM impact its bid ask spread?
A smaller fund does not necessarily mean wider bid-ask spreads. ETF liquidity is driven primarily by the liquidity of underlying holdings, not fund size alone. FMTM requires each portfolio holding to trade a minimum of $25 million daily. The holdings are highly liquid U.S. equities, meaning the underlying securities themselves are easy to trade even when the ETF's secondary market volume is light. That said, investors should still use limit orders and trade during normal market hours to ensure efficient execution.
6. Portfolio Overlap – How much overlap is there with SPMO?
SPMO draws exclusively from the S&P 500 and is therefore limited to large-caps. FMTM's broader universe includes large- and mid-cap companies, allowing it to capture momentum trends that may emerge earlier in mid-caps before they become large-caps. Because FMTM is not anchored to a market-cap-weighted index and uses equal-weight positioning, it avoids the concentration and index-hugging behavior common in passive funds. As a result, its holdings often differ meaningfully from traditional large-cap momentum ETFs, potentially enhancing diversification within the momentum factor.
7. Fees – Is FMTM’s higher expense ratio worth it?
SPMO charges 0.13%, while FMTM charges 0.45%. The difference reflects FMTM's active management and monthly rebalancing. The strategy incorporates a differentiated momentum signal focused on trend consistency and quality rather than simply ranking 12-month returns. While fees are an important consideration, investors should evaluate outcomes on more than just expense ratios alone. If a strategy’s structure leads to materially different performance or portfolio risk characteristics, the more relevant comparison is total return net of fees.
8. Performance Cycles – In what market environments might FMTM or SPMO underperform?
Both FMTM and SPMO are momentum strategies, and momentum can lag during sharp market reversals or highly volatile “whipsaw” environments where leadership changes quickly. SPMO may underperform when its semi-annual rebalance schedule prevents it from adjusting to new trends. FMTM, while more responsive due to monthly rebalancing, may underperform during narrow mega-cap-led rallies where equal-weight positioning lags market-cap weighted strategies. As with any factor exposure, periods of relative underperformance are a normal part of long-term implementation.
9. Portfolio Allocation – Should I hold FMTM in a Roth or retirement account due to its higher turnover?
Not necessarily. While FMTM's monthly rebalancing results in higher portfolio turnover, the ETF structure minimizes capital gain distributions through the in-kind creation and redemption process. Higher turnover does not automatically translate into taxable capital gains for shareholders. To date, FMTM hasn’t made any capital gains distributions and can be held in taxable or tax-advantaged accounts, depending on one’s portfolio structure. Investors should consult their tax professional to assess how FMTM or SPMO fit within their specific tax situation and overall asset location strategy.
When to Choose FMTM vs. SPMO
The choice between FMTM and SPMO depends on implementation preferences and portfolio objectives. Both can be used in taxable or tax-advantaged accounts. FMTM may appeal to investors willing to pay a higher fee for quantitative management focused on trend consistency and quality with built-in risk management. SPMO may suit investors prioritizing low cost and a traditional passive factor tilt. FMTM's approach to U.S. large- and mid-cap momentum is differentiated by its monthly rebalancing cadence, which enables faster response to shifting market leadership. This responsiveness appeals to investors seeking active momentum management rather than a fixed semi-annual rebalance schedule.
