If you’re looking for an ETF that aims to outperform the broader market by investing in stocks with strong price momentum, the SPMO ETF is one of the most popular options available today. Unlike a traditional S&P 500 index fund that simply holds the largest U.S. companies by market capitalization, the Invesco S&P 500 Momentum ETF (SPMO) focuses on companies that have recently demonstrated the strongest upward price trends.

Momentum investing has gained significant attention over the last decade because stocks that perform well over a sustained period often continue outperforming for some time. Instead of trying to predict which companies will become tomorrow’s winners, SPMO follows a rules-based strategy that selects approximately 100 momentum leaders from the S&P 500 Index and regularly updates its portfolio as market trends change.

This approach has helped the ETF deliver impressive returns during strong bull markets, particularly when technology and growth stocks lead the market. However, momentum investing also comes with unique risks, including higher volatility, greater portfolio turnover, and periods of underperformance when market leadership changes rapidly.

SPMO ETF Snapshot

What Is the SPMO ETF?

The SPMO ETF, officially known as the Invesco S&P 500 Momentum ETF, is a factor-based exchange-traded fund that invests in approximately 100 companies from the S&P 500 with the strongest momentum characteristics.

Rather than owning all 500 companies in the index, SPMO narrows its portfolio to businesses whose share prices have shown the strongest risk-adjusted upward momentum over recent months. The fund is designed to capture market leaders while reducing exposure to companies with weakening price trends.

Unlike actively managed funds, SPMO follows a transparent, rules-based methodology. This means investment decisions are based on predefined index rules instead of a portfolio manager’s opinions or forecasts.

For investors seeking greater growth potential than a traditional S&P 500 ETF, SPMO provides targeted exposure to stocks that have recently demonstrated sustained market strength.

Who Manages the SPMO ETF?

SPMO is managed by Invesco, one of the world’s largest global asset managers with hundreds of ETFs covering equities, fixed income, commodities, thematic investing, and smart-beta strategies.

The ETF tracks the S&P 500 Momentum Index, which is maintained by S&P Dow Jones Indices. Because the index provider sets the selection rules, Invesco’s role is to replicate the index as closely as possible rather than actively choosing stocks.

This passive structure helps keep costs relatively low while ensuring the investment process remains transparent and consistent.

How Does the SPMO ETF Work?

Many investors hear the phrase “momentum investing” but aren’t sure what it actually means. The strategy behind SPMO is more systematic than simply buying stocks that have recently gone up.

Here’s how the process works:

Start with the S&P 500

The index begins with companies already included in the S&P 500. These are generally large, established U.S. businesses across a wide range of industries.

Measure Risk-Adjusted Momentum

Each company is evaluated using risk-adjusted price momentum, which looks at:

• Price performance over the previous 6 to 12 months
• Volatility during that period
• Consistency of returns rather than short-term spikes

This approach rewards stocks that have delivered strong gains while avoiding those whose performance has been excessively volatile.

Rank Every Stock

After calculating momentum scores, all eligible companies are ranked from strongest to weakest.

Only the highest-ranking companies qualify for inclusion in the index.

Build the Portfolio

The ETF typically holds around 100 stocks with the strongest momentum scores.

Companies that lose momentum can be removed during scheduled rebalancing, while new leaders are added. This keeps the portfolio focused on current market trends rather than historical winners.

Semi-Annual Rebalancing

The index is rebalanced twice a year, usually in March and September.

During each rebalance:

• New momentum leaders are added.
• Stocks with declining momentum may be removed.
• Position weights are adjusted.
• Sector exposure can change significantly depending on market leadership.

This disciplined process helps the ETF adapt to changing market conditions without relying on human judgment.

Understanding Risk-Adjusted Momentum

One aspect that many articles overlook is how momentum is actually measured.

SPMO doesn’t simply buy stocks that rose the most last month. Instead, it favors companies with:

• Strong medium-term price appreciation
• Stable and consistent upward trends
• Lower volatility relative to their returns
• Persistent buying interest from the market

For example:

Even though Companies A and B produced the same return, Company A may receive a higher momentum score because its gains were achieved with less volatility.

This focus on risk-adjusted returns aims to improve the quality of momentum exposure rather than simply chasing the biggest winners.

Why Do Stocks Leave the SPMO ETF?

Many investors assume ETFs rarely change their holdings. That’s true for broad market funds like the S&P 500, but momentum ETFs are different.

A stock may be removed if:

• Its upward trend weakens.
• Other companies develop stronger momentum.
• Market leadership shifts to different sectors.
• The stock no longer ranks among the top momentum names.

This ongoing rotation helps SPMO stay aligned with the market’s strongest-performing companies, but it also leads to higher portfolio turnover than traditional index ETFs.

Who Is the SPMO ETF Designed For?

The Invesco S&P 500 Momentum ETF (SPMO) isn’t intended to replace a diversified core index fund for every investor. Instead, it works best as a satellite holding for investors seeking additional growth potential.

SPMO may be suitable if you:

• Want exposure to companies with strong price momentum.
• Believe market trends can persist over time.
• Already own diversified index funds and want a tactical growth allocation.
• Are comfortable with periods of higher volatility than the overall market.
• Prefer a transparent, rules-based investment strategy over active stock picking.

When evaluating an ETF, many investors focus only on performance and holdings. However, trading volume and liquidity are equally important because they determine how easily you can buy or sell shares without significantly affecting the market price.

The SPMO ETF is one of the largest momentum ETFs in the United States, with more than $20 billion in assets under management (AUM). Thanks to its size and active trading, SPMO generally offers excellent liquidity, making it suitable for both long-term investors and active traders.

Understanding how to interpret the SPMO ETF volume chart can also help you recognize periods of heightened market activity, institutional trading, and index rebalancing.

What Is Trading Volume?

Trading volume refers to the total number of ETF shares bought and sold during a trading session. Every time one investor buys shares and another sells them, that transaction contributes to the ETF’s daily trading volume.

Higher trading volume usually indicates:

• Strong investor interest
• Better market liquidity
• Faster order execution
• Smaller differences between buying and selling prices

Conversely, ETFs with very low trading volume may experience wider bid-ask spreads, making them more expensive to trade.

For SPMO, high daily trading activity is a positive sign because it allows investors to enter or exit positions efficiently.

Understanding the SPMO ETF Volume Chart

Most financial websites simply display a volume chart without explaining what it means. Learning to interpret the chart can help investors understand market sentiment and trading activity.

What the Chart Shows

A typical SPMO ETF volume chart consists of:

• Price Line: Tracks the ETF’s share price throughout the trading period.
• Volume Bars: Represent the number of shares traded during each day.
• Timeline: Displays trading activity over days, weeks, or months.

Higher bars indicate increased trading activity, while lower bars suggest quieter trading sessions.

How to Read the Volume Chart

When analyzing the chart, pay attention to the relationship between price movements and trading volume.

Professional investors often use volume to confirm whether a market trend is supported by strong participation.

Why Does SPMO’s Trading Volume Spike?

Large increases in trading volume are common for factor-based ETFs like SPMO. These spikes are often driven by predictable events rather than sudden changes in investor sentiment.

1. Semi-Annual Index Rebalancing

The S&P 500 Momentum Index is typically rebalanced in March and September.

During these periods:
Stocks with weakening momentum are removed.

New momentum leaders are added.

Portfolio weights are adjusted.

Institutional investors trade heavily to match the updated index.

This often results in significantly higher trading volume around the rebalance dates.

2. Corporate Earnings Season

Many of SPMO’s largest holdings are major technology and growth companies.

When companies report earnings that exceed or miss expectations, investors may rapidly buy or sell shares, increasing both stock and ETF trading volumes.

3. Major Market News

Events such as:

• Federal Reserve interest rate decisions
• Inflation reports
• Employment data
• Geopolitical developments

can lead to sharp increases in trading activity as investors reposition their portfolios.

4. Strong Market Trends

Momentum ETFs generally attract more attention during powerful bull markets. As investors seek exposure to the market’s strongest-performing stocks, trading volume often rises alongside prices.

What Is ETF Liquidity?

Liquidity measures how easily an ETF can be bought or sold without causing a significant change in its market price.

A highly liquid ETF allows investors to:

• Execute trades quickly
• Receive prices close to the quoted market value
• Minimize transaction costs

Because SPMO combines substantial assets with active daily trading, it is generally considered a highly liquid ETF.

Understanding the Bid-Ask Spread

Another key indicator of liquidity is the bid-ask spread.

• Bid Price: The highest price a buyer is willing to pay.
• Ask Price: The lowest price a seller is willing to accept.

The difference between these two prices is known as the bid-ask spread.

Example

A narrow spread means investors can trade efficiently with minimal additional cost.

For large ETFs like SPMO, bid-ask spreads are typically very tight under normal market conditions.

Why Tight Spreads Matter

Even a small difference in the bid-ask spread can affect long-term investment returns, particularly for active traders.

Long-term investors may not notice these costs frequently, but traders who buy and sell regularly should pay close attention to them.

Assets Under Management vs. Trading Volume

Many investors mistakenly believe that high assets automatically mean high liquidity.

While assets under management (AUM) are important, daily trading volume and the ETF creation/redemption process also contribute to liquidity.

A strong ETF generally performs well across all four metrics.

Is SPMO a Liquid ETF?

For most retail investors, the answer is yes.

The Invesco S&P 500 Momentum ETF (SPMO) offers:

• Billions of dollars in assets under management
• Active daily trading
• Tight bid-ask spreads
• Efficient order execution
• Strong institutional participation

These characteristics make SPMO suitable for investors who value both accessibility and trading efficiency.

Tips for Trading SPMO Efficiently

To reduce trading costs and improve execution quality, consider these best practices:

Review trading volume before executing unusually large transactions.

Trade during regular market hours when liquidity is highest.

Avoid placing large market orders immediately after the market opens or just before it closes.

Use limit orders instead of market orders to control the price you pay.

Be aware of increased volatility around March and September, when the ETF undergoes semi-annual rebalancing.

SPMO ETF Holdings

One of the biggest reasons investors choose the SPMO ETF over a traditional S&P 500 index fund is its carefully selected portfolio. Instead of investing in all 500 companies in the S&P 500, the Invesco S&P 500 Momentum ETF (SPMO) focuses on approximately 100 companies that currently exhibit the strongest risk-adjusted price momentum.

This selective approach allows the ETF to overweight companies leading the market while removing those that have lost momentum. As a result, the portfolio can look very different from a standard S&P 500 ETF such as SPY, especially during periods when technology, artificial intelligence (AI), or other high-growth sectors dominate market performance.

Because the portfolio is rules-based and rebalanced semi-annually, the holdings evolve over time to reflect changing market leadership rather than remaining static.

How Does SPMO Select Its Holdings?

Unlike actively managed funds, SPMO does not rely on portfolio managers to pick stocks.

Instead, the ETF follows a transparent methodology based on the S&P 500 Momentum Index.

The selection process generally works as follows:

1. Start with all eligible companies in the S&P 500.
2. Calculate each company’s risk-adjusted momentum score using historical price performance and volatility.
3. Rank every company from highest to lowest momentum.
4. Select approximately the top 100 companies.
5. Assign portfolio weights based on the index methodology.
6. Rebalance the portfolio every March and September.

This disciplined process removes emotional decision-making and ensures the portfolio always reflects current market trends.

Top 10 SPMO ETF Holdings

The largest holdings in SPMO typically include companies that have delivered strong earnings growth, positive price momentum, and sustained institutional buying.

What Do These Holdings Tell Investors?

The top holdings reveal several important characteristics of the SPMO ETF.

Strong Focus on Market Leaders

Unlike a traditional index fund that gives every S&P 500 company exposure based on market capitalization, SPMO concentrates on businesses showing the strongest recent momentum.

Many of these companies are industry leaders with:

• Rapid revenue growth
• Strong earnings momentum
• Consistent institutional demand
• Leadership in emerging technologies

This concentration allows SPMO to benefit when market leaders continue outperforming.

Heavy Technology Exposure

Technology has been one of the strongest-performing sectors in recent years.

As a result, SPMO often allocates a significant portion of its portfolio to companies involved in:

• Artificial Intelligence
• Cloud Computing
• Semiconductor Manufacturing
• Software
• Data Centers
• Cybersecurity

This explains why technology frequently represents the largest sector within the ETF.

However, investors should remember that high exposure to one sector increases both potential returns and portfolio risk.

Sector Allocation

Sector allocations change after every rebalance, but technology has consistently represented the largest portion of the portfolio.

Below is an example of how the allocation may look.

Why Technology Dominates the Portfolio

Some investors wonder why SPMO often appears heavily invested in technology stocks.

The answer lies in the ETF’s methodology.

Technology companies frequently demonstrate:

• Faster earnings growth
• Higher revenue expansion
• Greater investor demand
• Strong price momentum

Since SPMO selects stocks based on momentum rather than sector targets, technology naturally receives a larger allocation whenever it leads the market.

This is not intentional sector bias—it is a byproduct of the momentum strategy.

Top Holdings Concentration

Another important metric is the concentration of the ETF’s largest positions.

The top 10 holdings often account for approximately 48–52% of the entire portfolio.

A concentrated portfolio can outperform when its largest holdings continue to lead the market. However, it can also experience sharper declines if those companies underperform.

Geographic Exposure

Unlike global ETFs, SPMO focuses almost entirely on the United States.

Investors seeking international diversification may combine SPMO with a global fund such as the VT ETF, which provides exposure to developed and emerging markets around the world.

How Often Do the Holdings Change?

The holdings are reviewed and updated twice each year, typically in:

• March
• September

During each rebalance:

• Companies with declining momentum may be removed.
• New momentum leaders enter the portfolio.
• Existing weights are adjusted to reflect updated momentum scores.

Because of this process, investors should expect the holdings list to evolve over time rather than remain fixed.

Why the Holdings Matter

Understanding the SPMO ETF holdings helps investors evaluate the fund’s risks and opportunities.

For example:

Higher Growth Potential

Companies with strong momentum often continue outperforming during favorable market conditions.

Increased Volatility

Concentrated exposure to fewer stocks means individual companies can have a larger impact on returns.

Sector Risk

Heavy exposure to technology and communication services may cause SPMO to outperform during tech-led rallies but underperform when leadership rotates into defensive sectors.

Less Diversification

While SPMO holds around 100 stocks, it is still less diversified than a traditional S&P 500 ETF with 500 holdings.

SPMO Holdings vs. SPY Holdings

Many investors compare SPMO with the SPDR S&P 500 ETF (SPY). Although both invest in large U.S. companies, their portfolios are constructed very differently.

If your goal is broad market exposure, SPY may be the better choice. If you’re seeking a factor tilt with the potential for higher returns, SPMO offers a more targeted approach.

SPMO ETF Expense Ratio

When comparing exchange-traded funds, many investors focus on returns while overlooking one of the most important long-term factors: cost.

Every ETF charges an annual management fee, known as the expense ratio, which covers portfolio management, administration, index licensing, and operating expenses. Although the percentage may appear small, investment costs compound over time and can reduce your overall returns.

The Invesco S&P 500 Momentum ETF (SPMO) has an expense ratio of 0.13%, making it competitively priced among smart-beta and factor ETFs. While it costs more than a basic S&P 500 index fund, it remains less expensive than many actively managed funds and several specialized momentum strategies.

What Is the SPMO ETF Expense Ratio?

The expense ratio is the percentage of your investment deducted each year to cover the ETF’s operating expenses.

For SPMO:

• Expense Ratio: 0.13% per year

This fee is not billed separately. Instead, it is automatically reflected in the ETF’s net asset value (NAV), so investors never receive a direct invoice.

Example

If you invest $10,000 in SPMO:

• Annual management cost = $13
• Remaining assets continue to grow based on market performance.

This is one reason ETFs remain one of the most cost-efficient investment vehicles available.

How Much Does SPMO Cost?

A percentage like 0.13% may seem abstract, so it’s helpful to translate it into real dollars.

Example

Imagine two investors each earn the same market return:

• Investor A chooses a fund with a 0.03% expense ratio.
• Investor B chooses SPMO with a 0.13% expense ratio.

Investor B pays a slightly higher annual fee, but if SPMO’s momentum strategy generates higher returns over time, that additional cost may be justified.

This highlights an important principle:

Investors should evaluate both fees and performance rather than focusing solely on the lowest expense ratio.

Is 0.13% a Good Expense Ratio?

For a factor-based ETF, yes.

SPMO follows a specialized momentum strategy that requires:

• Regular index screening
• Portfolio rebalancing
• Higher portfolio turnover
• Continuous index maintenance

Despite these additional requirements, the fund’s 0.13% expense ratio remains competitive.

Below is a general comparison with similar ETF categories.

Compared with many factor-based funds, SPMO sits toward the lower end of the cost range.

SPMO vs. Other Momentum ETFs

One of the best ways to evaluate SPMO’s costs is to compare it with similar momentum-focused ETFs.

What This Comparison Shows

• VOO is cheaper because it simply tracks the S&P 500.
• SPY also has a lower fee but serves a different purpose.
• SPMO charges slightly more because it follows a momentum factor strategy.
• QMOM generally costs more due to its specialized quantitative methodology.

For investors specifically seeking momentum exposure, SPMO offers a strong balance between cost and strategy.

Is the Higher Fee Worth It?

This is one of the most common questions investors ask.

The answer depends on whether SPMO’s momentum strategy continues to outperform traditional market-cap-weighted funds over your investment horizon.

The Extra Fee May Be Worth Paying If You:

• Want targeted exposure to momentum stocks.
• Believe market leaders can continue outperforming.
• Are comfortable with higher volatility.
• Use SPMO as a satellite position in a diversified portfolio.

The Extra Fee May Not Be Worth Paying If You:

• Simply want to match the S&P 500.
• Prefer the lowest possible investment costs.
• Value maximum diversification over factor tilts.
• Intend to build a passive, buy-and-hold portfolio.

Does the Expense Ratio Affect Returns?

Yes—but context matters.

Every ETF deducts expenses before reporting returns, meaning published performance figures are already net of fees.

For example:

Suppose two ETFs each earn a 10% gross return before expenses.

The difference is relatively small over one year.

However, over decades, costs can compound. That’s why investors should balance fees against the potential for higher returns.

Expense Ratio vs. Trading Costs

Many beginners confuse the expense ratio with brokerage commissions.

These are different costs.

Today, many online brokers offer commission-free ETF trading, meaning the expense ratio and bid-ask spread are often the primary costs investors need to consider.

Hidden Costs Investors Should Know

Although SPMO has a competitive expense ratio, investors should also understand the indirect costs associated with a momentum strategy.

Portfolio Turnover

Because SPMO rebalances twice each year, it generally has higher portfolio turnover than a standard S&P 500 ETF.

Higher turnover can:

• Increase trading activity within the fund.
• Create taxable capital gains distributions in some years.
• Slightly increase transaction costs inside the portfolio.

These indirect costs are not included in the published expense ratio but are worth considering, particularly for taxable brokerage accounts.

Tax Considerations

One area many competing articles ignore is taxation.

SPMO is generally tax-efficient because it is an ETF, but its momentum strategy may result in higher turnover than a passive index fund.

Investors holding SPMO in taxable accounts should be aware that:

• Semi-annual rebalancing may increase realized capital gains.
• Dividend distributions are generally taxable unless held in tax-advantaged accounts.
• Tax consequences vary based on your country of residence and personal circumstances.

If you’re investing for retirement through a tax-advantaged account, these issues may be less significant.

Expense Ratio vs. Performance

The goal isn’t to find the cheapest ETF.

The goal is to maximize risk-adjusted returns after fees.

For example:

Choosing an ETF should always begin with your investment objective—not just its annual fee.

Analyst Verdict

The SPMO ETF expense ratio of 0.13% is reasonable considering the specialized momentum strategy it provides.

Although it costs slightly more than traditional index ETFs, investors receive:

• A disciplined factor-investing methodology.
• Regular portfolio rebalancing.
• Exposure to high-momentum market leaders.
• A transparent, rules-based investment process.

For investors specifically seeking momentum exposure, the additional cost is modest and may be justified if the strategy continues to outperform over full market cycles.

Conclusion: Is the SPMO ETF Worth Buying in 2026?

The SPMO ETF is one of the strongest options for investors seeking exposure to the momentum factor within the U.S. stock market. Rather than holding every company in the S&P 500, the Invesco S&P 500 Momentum ETF focuses on approximately 100 stocks that have demonstrated the strongest risk-adjusted price momentum.

Throughout this guide, we’ve covered everything from the SPMO ETF price, holdings, holdings list, expense ratio, volume and liquidity, and investment strategy to help you determine whether this ETF aligns with your financial goals.

One of SPMO’s biggest strengths is its disciplined, rules-based approach. The fund automatically adjusts its portfolio during semi-annual rebalancing, ensuring that it continues investing in companies showing the strongest momentum rather than relying on subjective stock picking. This strategy has historically performed well during periods when technology, AI, and growth stocks lead the market.

However, no ETF is perfect. Because SPMO is more concentrated than a traditional S&P 500 fund, investors should expect higher volatility and periods of underperformance when market leadership shifts. Its higher portfolio turnover also makes it slightly less tax-efficient than a passive index ETF in taxable accounts.

Our Verdict

If you are:

• Looking for long-term exposure to high-quality momentum stocks
• Comfortable with greater short-term volatility
• Already own a diversified core ETF and want a growth-oriented satellite investment
• Interested in factor investing without actively picking stocks

then the SPMO ETF deserves serious consideration.

On the other hand, if your priority is maximum diversification or the lowest possible investment costs, a broad-market ETF such as the VT ETF or a traditional S&P 500 fund may be a better foundation for your portfolio.

The best approach for many investors is to use SPMO as a complement to a diversified portfolio rather than as a complete replacement for a total-market fund.

As always, review the fund’s latest holdings, performance, and investment objectives before making any investment decision, and ensure it matches your risk tolerance and long-term financial plan.
