When it comes to investing in aerospace and defense ETFs, three funds stand out: ITA, PPA, and XAR. Each offers a distinct approach, catering to different investment goals, risk tolerances, and market conditions. Here’s a quick breakdown:

  • ITA (iShares U.S. Aerospace & Defense ETF): Focuses on large, established companies like Boeing and Lockheed Martin. It’s ideal for investors seeking stability and exposure to top-tier players. Expense ratio: 0.38%.
  • PPA (Invesco Aerospace & Defense ETF): Offers broader exposure, balancing large, mid, and smaller companies, including emerging sectors like space tech and cybersecurity. A more diversified option but with a higher expense ratio of 0.58%.
  • XAR (SPDR S&P Aerospace & Defense ETF): Uses an equal-weighted strategy, emphasizing smaller and mid-cap companies. This fund is more volatile but has higher growth potential during economic recoveries. Expense ratio: 0.35%.

Key Takeaway:

  • Choose ITA for stability and focus on industry leaders.
  • Opt for PPA if you prefer diversification across the sector.
  • Select XAR if you’re targeting growth and are comfortable with higher risk.

ETF Battles: Which Aerospace & Defense ETFs are the Best Choice?

iShares U.S. Aerospace & Defense ETF (ITA): Analysis

The iShares U.S. Aerospace & Defense ETF (ITA) offers a focused way for investors to tap into the aerospace and defense sector. By utilizing a market-cap weighted strategy, the fund zeroes in on the industry's biggest players, making it a go-to option for those interested in this specialized market.

ITA Structure and Holdings

ITA's portfolio is built around a selection of companies from the aerospace and defense space, with a strong lean toward large, well-established contractors. Key names often featured in its holdings include industry giants like RTX Corporation, Boeing, and Lockheed Martin. This focus mirrors the dynamics of the sector, where a handful of dominant companies secure the bulk of high-value government and commercial contracts.

While the fund also includes smaller suppliers to add some level of diversification, their influence remains limited due to ITA's preference for larger market-cap companies. This concentrated approach makes ITA highly responsive to major developments, such as contract awards, which can significantly impact its performance during periods of market growth.

ITA Performance During Market Upswings

Thanks to its emphasis on leading industry players, ITA has demonstrated strong performance during times of increased defense budgets or a rebound in commercial aviation demand. These cyclical trends in the aerospace and defense sectors often drive the fund's returns. For instance, when a top holding secures a significant contract or reports robust earnings, ITA tends to benefit directly. However, this same concentration can work against the fund if one of its major holdings faces setbacks, amplifying the downside.

For investors seeking capital growth during economic recoveries or periods of heightened defense spending, ITA's focus on top-tier companies can be appealing. Furthermore, the ETF's liquidity ensures that investors can easily enter or exit positions, offering flexibility to adapt as market conditions shift.

Invesco Aerospace & Defense ETF (PPA): Analysis

The Invesco Aerospace & Defense ETF (PPA) takes a broader approach to the sector compared to ITA, offering a more balanced and diversified exposure by including a wider range of companies.

PPA Structure and Holdings

PPA’s balanced strategy is evident in its portfolio structure. The fund uses a weighting methodology that ensures a more even distribution across its holdings. While it includes major players like Northrop Grumman, General Dynamics, and Raytheon Technologies, it also reserves significant allocations for mid-sized companies and smaller suppliers. This approach prevents any single company from dominating the fund's performance.

The ETF holds a mix of firms involved in manufacturing aircraft components, defense electronics, and satellite systems. Its diversified focus also extends to emerging areas such as unmanned systems, space technology, and cybersecurity - sectors that are often overlooked in more concentrated funds. This broad reach helps the fund maintain strong liquidity and ensures exposure to both established giants and up-and-coming innovators. The expense ratio reflects the active management necessary to uphold this balanced strategy.

PPA Performance During Market Upswings

This diversification provides a performance edge, particularly during periods of economic recovery or increased defense spending. Unlike funds that rely heavily on a few large contractors, PPA benefits from growth across the entire sector. Whether it’s a rebound in commercial aviation or a boost in defense budgets, the fund captures gains from both industry leaders and smaller firms supplying critical components and services.

PPA’s structure also helps cushion the impact of market volatility. If one major holding underperforms, the fund’s diversified exposure reduces the overall effect on its performance. This makes it an appealing option for investors who want exposure to the aerospace and defense sector without the heightened risks of a concentrated portfolio.

Additionally, PPA offers modest dividend income, combining growth potential with a steady income stream, particularly during economic recoveries. For those aiming to capitalize on cyclical upswings in the sector while spreading risk across a broad range of companies, PPA’s diversified approach strikes a compelling balance.

SPDR S&P Aerospace & Defense ETF (XAR): Analysis

Unlike ITA and PPA, the SPDR S&P Aerospace & Defense ETF (XAR) uses an equal-weighted strategy, giving the same allocation to each holding. This design shifts the focus toward smaller companies in the aerospace and defense sector, making it a standout option worth examining.

XAR Structure and Holdings

XAR's equal-weight approach ensures every company in the portfolio gets an identical allocation, typically ranging between 2.5% and 3.3% at rebalancing. This results in a portfolio of 30 to 40 holdings, offering a more balanced exposure compared to funds that use market-cap weighting.

This methodology increases the presence of mid-cap and small-cap companies, setting XAR apart from ITA or PPA. While it still includes industry heavyweights like Lockheed Martin and Boeing, XAR also highlights smaller firms specializing in areas like precision manufacturing, advanced materials, satellite communications, and defense software. These niche players, often overlooked in market-cap-weighted funds, can make up a significant portion of XAR's portfolio.

Quarterly rebalancing enforces a disciplined approach, redistributing gains from top-performing stocks to underweighted ones. While this can lead to higher turnover and slightly elevated expense ratios, it maintains balance and a "buy-low, sell-high" dynamic. Though XAR typically manages fewer assets than ITA, which might pose liquidity challenges for institutional investors, retail traders usually find sufficient trading volume for their needs.

XAR Performance During Market Upswings

XAR's equal-weight strategy offers both opportunities and risks, particularly during market upswings. Smaller companies, often more sensitive to economic growth, can outperform large-cap peers, driving stronger returns. For instance, a $1 billion contract might significantly impact a small firm's earnings, while barely affecting a $100 billion corporation.

This trend has been evident in past defense spending cycles, where smaller suppliers and specialized manufacturers often reaped outsized gains as their fundamentals improved and investor interest grew. However, this potential for higher returns comes with increased volatility. Small-cap stocks are naturally more prone to price swings, and XAR reflects this, often underperforming during downturns or periods of sector weakness. Smaller firms tend to have less diversified revenue streams and may face more financial strain in challenging times.

The quarterly rebalancing also shapes XAR's performance. By selling outperforming stocks and buying underperformers, the fund may lag in markets dominated by a few large-cap winners. On the other hand, it can shine during broad recoveries when the entire sector rebounds, benefiting from mean reversion as underperforming stocks catch up.

XAR is not a strong choice for dividend income, as many of its holdings prioritize reinvesting profits into growth rather than distributing cash to shareholders.

For investors seeking exposure to cyclical upswings and willing to embrace higher risk, XAR's focus on smaller companies and its equal-weight strategy offer unique opportunities. This fund thrives when sector-wide growth lifts smaller firms more rapidly, making it particularly appealing for those who can identify cyclical lows and remain patient through the inevitable volatility of small-cap investing.

ITA vs PPA vs XAR: Side-by-Side Comparison

Expense ratios play a significant role in shaping net returns, as lower fees allow more of your investment to grow over time.

Key Metrics Comparison Table

Metric ITA PPA XAR
Expense Ratio 0.38% 0.58% 0.35%

As the table illustrates, both ITA and XAR come with lower expense ratios (0.38% and 0.35%, respectively) compared to PPA's 0.58%. While the difference might seem small - just 0.23 percentage points - it can have a meaningful impact over the long term. Even slight variations in fees add up, compounding over time and potentially creating a noticeable performance gap. For investors, these differences in expenses are worth considering when choosing an ETF.

Choosing the Right Defense ETF for Your Portfolio

Selecting the best defense ETF for your portfolio depends on your financial goals and circumstances. With the ETF structures previously discussed, let’s break down the key factors to guide your decision.

What to Consider When Selecting a Defense ETF

When evaluating defense ETFs like ITA, PPA, and XAR, there are several critical elements to keep in mind:

  • Expense Ratios: Even small differences in fees can add up significantly over time, so it’s important to pay attention to these costs.
  • Weighting Methods: ETFs use different strategies to allocate their holdings. Market-cap-weighted funds, for instance, focus heavily on industry giants such as Lockheed Martin and Boeing. On the other hand, equal-weighted funds spread exposure more evenly across a broader range of companies. This choice impacts how concentrated your investment is in a few major players versus a more diverse set of firms.
  • Concentration Risk: Funds that focus on a small number of companies can increase your exposure to specific contractors. Tools like Mezzi's X-Ray feature can help identify hidden risks and ensure your portfolio isn’t overly concentrated.
  • Dividend Income vs. Capital Appreciation: Decide whether you’re looking for consistent dividend payouts or long-term growth. While defense ETFs don’t typically offer the high dividends seen in sectors like utilities, they can still provide moderate income. Reviewing an ETF’s distribution history is key to finding one that fits your needs.
  • Fund Size and Liquidity: Larger ETFs often offer tighter bid-ask spreads and easier trading. For example, ITA, the largest defense-focused ETF, holds $12.4 billion in net assets as of November 2025. PPA and XAR manage $6.8 billion and $4.7 billion, respectively. While all three are liquid enough for most investors, larger funds tend to inspire greater investor confidence.

Matching ETFs to Different Investor Profiles

Each ETF caters to different investment goals, so it’s helpful to consider how they align with your objectives:

  • Growth-Focused Investors: If you’re seeking higher returns, look at historical performance. For instance, PPA has delivered a 17.2% annualized return over the last decade, with XAR close behind at 16.5%.
  • Income-Oriented Investors: While defense ETFs aren’t typically income-focused, they can still provide moderate dividends. Those nearing retirement or with shorter time horizons might prioritize funds with a reliable payout history.
  • Risk-Conscious Investors: If market volatility concerns you, consider limiting your exposure to defense ETFs. These funds are tied to a specific sector, which can amplify risks during downturns.
  • Tax-Sensitive Investors: Concentrated industry investments may lead to taxable events during rebalancing. Platforms like Mezzi offer tax optimization tools to help manage your portfolio efficiently, tracking cost basis and holding periods to minimize unnecessary taxes.

Finally, consider your overall portfolio. If you already own individual defense stocks or broader market ETFs, adding a defense-specific fund might create overexposure. On the flip side, if you lack defense sector exposure and see potential in its cyclical growth, these ETFs could be a smart way to diversify.

The best defense ETF isn’t a one-size-fits-all solution. It’s the one that aligns with your goals, risk tolerance, and investment timeline. Take the time to evaluate your unique situation to make the right choice for your portfolio.

Managing Defense ETF Investments with Mezzi

Mezzi

Once you've chosen a defense ETF that fits your investment strategy, the next step is managing it effectively. Mezzi's platform offers a suite of tools to help you optimize your holdings, monitor your portfolio across accounts, and improve after-tax returns - all without the hefty fees that typically come with financial advisors.

Using Portfolio Analysis Tools

After selecting a defense ETF, managing it efficiently is crucial, and Mezzi makes this process seamless. Whether you're investing in funds like ITA, PPA, or XAR, understanding your overall exposure is essential. Mezzi's account aggregation feature consolidates all your investment accounts into a single view, giving you a comprehensive picture of your holdings.

One standout feature for defense ETF investors is the X-Ray tool. If you own multiple defense ETFs or individual defense stocks alongside these funds, you might unknowingly be overexposed to certain companies. The X-Ray tool digs into your portfolio to reveal these hidden overlaps, showing you the underlying stocks across all your ETFs and accounts. For instance, you may find you're heavily concentrated in companies like Lockheed Martin, RTX Corporation, or Boeing. This insight is particularly valuable during market upswings when defense stocks are performing well, as it's easy for concentration risks to go unnoticed.

Additionally, Mezzi’s platform offers real-time AI alerts to flag potential issues in your portfolio. Instead of relying on periodic reports, the system continuously monitors your investments, providing timely suggestions or warnings. For defense ETF investors, this means you’ll receive alerts about imbalances or overexposure before they become significant problems. These tools are designed to help you stay on top of your portfolio, especially during the cyclical highs of the defense sector.

Improving Tax Efficiency on ETF Gains

Managing the tax implications of your investments is another critical aspect, and Mezzi simplifies this process. Defense ETFs often generate taxable events, such as dividend distributions and capital gains, especially during strong market periods when you might be rebalancing or taking profits. Proper tax management can make a significant difference in your long-term returns.

Mezzi’s tax optimization tools are built to tackle these challenges. For example, the platform helps you avoid wash sales - a common pitfall for investors. A wash sale occurs when you sell a security at a loss and repurchase the same or a similar one within 30 days, which disqualifies the tax deduction for that loss. For defense ETF investors, this can happen more easily than you think. If you sell ITA at a loss in one account but your automated investment plan buys PPA in another within the 30-day window, you could trigger a wash sale since both funds hold similar positions.

Mezzi automates the tracking of these transactions across all your accounts, offering timely suggestions that could save you thousands in taxes and fees. This automation ensures you can avoid wash sale violations while staying aligned with your investment strategy. It also simplifies complex strategies like tax-loss harvesting and managing long-term versus short-term capital gains. For example, when rotating between defense ETFs during a market upswing, Mezzi provides a clear view of the tax implications before you execute any trades.

Another helpful feature is Mezzi’s Financial Calculator, which projects how taxes and fees affect your long-term wealth accumulation. By factoring in asset manager fees, you can see the true cost of your investment choices over time. This is particularly useful when comparing defense ETFs with varying expense ratios, as even small differences in fees can compound into significant costs over decades.

Mezzi offers two membership options to suit different needs: the Build Wealth Faster Membership at $199/year, which includes tax optimization and AI-driven investment guidance, and the White Glove Membership at $499/year, which adds personalized coaching. For investors managing substantial defense ETF positions, the potential tax savings from avoiding just one wash sale violation could easily justify the membership cost.

Conclusion

Deciding between ITA, PPA, and XAR comes down to your specific investment goals and how much risk you're comfortable taking. XAR leans toward growth with its focus on mid- and small-cap stocks and offers the lowest fees. ITA prioritizes stability by concentrating on large-cap companies, while PPA provides a mix of the two strategies.

But choosing the right fund is just part of the equation. Paying attention to cost-efficiency and strategic management can make a big difference. Lower fees can add up to substantial savings over time, especially during prolonged market growth.

Tools like Mezzi can simplify the process by consolidating your accounts, identifying concentration risks, and automating tax strategies. This helps you stay balanced and avoid expensive mistakes.

FAQs

How do ITA, PPA, and XAR compare in terms of risk and growth potential?

The main difference between ITA, PPA, and XAR lies in how they allocate weight to companies in the defense and aerospace sector. ITA uses a market-cap weighting model, which tends to concentrate more heavily on larger firms. PPA takes a modified market-cap approach, spreading exposure more evenly by limiting the influence of the biggest players. Meanwhile, XAR opts for an equal-weighted strategy, distributing investments evenly across all its holdings for broader diversification.

These distinct strategies influence both risk and growth potential. ITA’s focus on larger companies can make it more volatile, especially during market fluctuations. PPA strikes a balance, reducing the dominance of top companies and lowering concentration risks. XAR’s equal weighting offers consistent diversification, though it might lag behind when large-cap stocks dominate the market. Selecting the right ETF comes down to your investment objectives and how much risk you’re willing to take, especially during times of economic growth or increased defense spending.

How do the expense ratios of ITA, PPA, and XAR influence long-term returns?

Expense ratios are a key factor in determining the long-term growth of your investments. These annual fees are taken from an ETF's assets, meaning the lower the expense ratio, the more of your money stays invested and has the chance to grow. On the flip side, higher expense ratios can chip away at your returns over time, particularly in a long-term portfolio.

When looking at ITA, PPA, and XAR, it's important to weigh their expense ratios alongside other considerations like performance and sector exposure. In some cases, paying a slightly higher expense ratio could make sense if the ETF consistently delivers strong results or aligns closely with your overall investment goals.

Which defense and aerospace ETF offers the best mix of diversification and growth potential during economic recoveries?

The Invesco Aerospace & Defense ETF (PPA) offers investors a compelling way to tap into the aerospace and defense sector while maintaining a diversified portfolio. This ETF includes a mix of established industry giants and forward-thinking companies, making it a solid option for those aiming to balance growth potential with stability.

PPA's allocation spans key players in the sector, positioning it to take advantage of rising defense budgets and market rebounds during economic recoveries. Its track record and variety of holdings provide a solid foundation for investors looking to harness growth opportunities without putting all their eggs in one basket.
