HACK: Amplify Cybersecurity ETF

Launched in 2014, HACK is one of the longest-standing cybersecurity ETFs, giving it a solid track record in the market. The fund follows the Nasdaq ISE Cyber Security Select Index and is entirely dedicated to companies in the cybersecurity field. This includes areas like network security, encryption, data protection, and threat detection.

HACK structures its portfolio by dividing it into two key segments: cybersecurity developers and service providers. It then weights these segments proportionally based on their combined market capitalization, while individual holdings within each segment are equally weighted. This approach results in a focused portfolio of about 26 holdings.

As of November 2025, HACK manages approximately $2.2 billion in assets under management. The fund comes with an expense ratio of 0.60%, which is relatively high compared to some other options in the cybersecurity ETF space. Its weighted average market cap sits at around $25 billion, giving it a noticeable small-cap orientation compared to its peers.

What HACK Does Well

HACK's primary strength lies in its dedicated focus on cybersecurity. Unlike broader technology ETFs that only include cybersecurity as one of many sectors, HACK zeroes in on companies whose main business is safeguarding digital assets and infrastructure. This concentrated strategy allows the fund to fully capitalize on growth within the cybersecurity industry.

The equal-weighting approach within each segment ensures that no single company dominates the portfolio. This gives smaller, potentially high-growth firms significant representation alongside more established players. For investors optimistic about the long-term expansion of the cybersecurity sector, HACK offers targeted exposure to this theme.

Additionally, HACK's small-cap tilt may appeal to growth-focused investors. Smaller companies often have more room to grow and can adapt quickly to emerging threats, developing cutting-edge solutions. This positioning could allow HACK to benefit from the rise of the next wave of cybersecurity leaders. However, these potential rewards come with corresponding risks.

Where HACK Falls Short

HACK's concentrated strategy does have its drawbacks. Its 0.60% expense ratio is higher than some competitors, such as BUG, which has a lower expense ratio of 0.51%.

The fund's small-cap focus and limited portfolio of 26 holdings can lead to increased volatility. With a weighted average market cap of about $25 billion - roughly half that of CIBR - HACK may be more susceptible to market swings compared to ETFs that include larger, more established companies.

For investors seeking a mix of stability and growth, HACK's aggressive approach might feel too risky, making it less suitable for those with a more conservative risk tolerance.

CIBR: First Trust NASDAQ Cybersecurity ETF

First introduced in 2015, CIBR has grown into a powerhouse, managing $11.06 billion in assets as of November 28, 2025. This makes it the largest dedicated cybersecurity ETF, earning top liquidity ratings from ETFdb.com. To put its dominance into perspective, competitors like HACK manage $2.21 billion, while BUG holds $1.00 billion. With such a solid foundation, it’s worth diving into what makes CIBR stand out - and where it might leave investors wanting more.

What CIBR Excels At

One of CIBR's standout features is its strong liquidity, which ensures smooth and efficient trading. Its diversified portfolio helps reduce concentration risk while still keeping investors tied to the broader cybersecurity theme. By focusing on large-cap companies, the fund leans on industry leaders with established track records and consistent revenue streams, offering a sense of stability for investors.

Potential Drawbacks of CIBR

However, CIBR’s broad investment strategy has its compromises. By spreading its focus, the fund may dilute its exposure to the core cybersecurity sector, which could limit gains during periods of rapid growth in the industry. Additionally, its preference for large-cap firms means less exposure to smaller, high-growth companies that often thrive during bullish markets.

For investors looking for concentrated exposure to the explosive growth potential within cybersecurity, CIBR’s more conservative approach might feel a bit too restrained.

BUG: Global X Cybersecurity ETF

Introduced in late 2019, BUG zeroes in on smaller, fast-growing cybersecurity companies. This focus provides exposure to emerging leaders in the field, which could translate into higher long-term returns. However, this concentrated approach also comes with increased volatility and certain risks. Let’s take a closer look at BUG's challenges and cost implications.

Where BUG Faces Challenges

BUG’s targeted strategy can lead to significant price swings, especially during market downturns. On top of that, the fund carries an expense ratio of 0.51%, which can add up over time and impact long-term returns. Since the fund has only been around since late 2019, its limited track record makes it harder to gauge how it might perform across varying market conditions. For investors who value stability, these factors might be less appealing. On the flip side, those with a higher risk tolerance may view the fund’s potential for long-term growth as worth the trade-offs.

Performance and Risk Comparison

When assessing the returns and risks of these ETFs, historical data offers valuable insights into their market behavior. Below is a table summarizing key performance metrics as of November 28, 2025.

Performance Metrics Table

Metric	HACK	CIBR	BUG
Sharpe Ratio	0.47	0.59	-0.29
Daily Standard Deviation	25.74%	24.19%	26.69%
Maximum Drawdown	-42.68%	-33.89%	-41.66%
Rolling 1-Month Volatility	6.58%	5.94%	8.19%

CIBR stands out with a Sharpe Ratio of 0.59, reflecting better risk-adjusted returns compared to HACK's 0.47. In contrast, BUG's Sharpe Ratio of -0.29 suggests its returns do not adequately compensate for its risk levels.

Risk Profiles

Looking at volatility, BUG exhibits the highest daily standard deviation at 26.69%. HACK follows at 25.74%, while CIBR shows the least volatility at 24.19%. The rolling one-month volatility paints a similar picture - BUG leads with 8.19%, significantly higher than HACK's 6.58% and CIBR's 5.94%.

Maximum drawdowns further highlight these differences. CIBR's -33.89% is the smallest, signaling greater resilience, while HACK and BUG experience deeper drawdowns at -42.68% and -41.66%, respectively.

Expense Ratios and Long-Term Costs

Fees can quietly eat into your investment returns over time. While expense ratios on cybersecurity ETFs might look minor at first glance, they can have a noticeable impact when compounded over the years.

Take HACK, for example, which charges an annual expense ratio of 0.60%. That means for every $1,000 you invest, you'll pay about $6.00 in fees each year. CIBR is slightly cheaper at 0.59%, costing $5.90 per $1,000 invested. Meanwhile, BUG offers an even lower expense ratio at 0.51%.

Now, let’s scale that up. For a $50,000 investment, CIBR would cost you approximately $295 annually, compared to HACK’s $300. That $5 difference might seem trivial, but over time, as your portfolio grows, these small distinctions add up.

If two funds have similar holdings, performance, and risk levels, the fund with the lower expense ratio often becomes the smarter choice. For long-term investors, every basis point counts. These seemingly minor fee differences can shape your portfolio's growth trajectory in the years ahead.

Portfolio Holdings and Sector Breakdown

When evaluating ETFs, understanding their composition is just as important as considering their fees. Each fund employs a unique strategy for selecting companies, weighting positions, and allocating sectors - factors that significantly influence your investment's risk and potential return.

CIBR holds a portfolio of 34 companies, HACK includes 26, and BUG comprises 30. However, a higher number of holdings doesn't automatically mean better diversification - weighting plays a crucial role. These structural elements tie directly to the performance and risk factors discussed earlier.

Sector Allocation

Both CIBR and HACK focus heavily on Technology Services. CIBR allocates 73.63% of its portfolio to this sector, while HACK dedicates 68.92%. Beyond this, their allocations diverge slightly. CIBR invests 23.61% in Electronic Technology and 2.34% in Commercial Services. In contrast, HACK leans more into Electronic Technology with 30.82% and allocates only 0.28% to Miscellaneous categories. This difference highlights HACK's concentrated bet on electronic technology companies, whereas CIBR spreads its investments more broadly across service-oriented firms.

Market Capitalization

Market cap allocation reveals another key distinction. CIBR leans toward larger, more established companies, with 85.61% in large-cap, 11.91% in mid-cap, 1.87% in small-cap, and 0.2% in micro-cap stocks. HACK, on the other hand, offers more exposure to smaller companies, allocating 75.82% to large-cap, 13.8% to mid-cap, and 10.1% to small-cap stocks without any micro-cap exposure. If you're drawn to the growth potential of smaller, emerging cybersecurity players, HACK's higher small-cap allocation might align with your goals. Meanwhile, CIBR's emphasis on large-cap companies may appeal if you prioritize the stability of established industry leaders.

Geographic Exposure

Geographic diversification also sets these funds apart. CIBR allocates 93.65% to the Americas, 4.2% to Europe, and 1.73% to Asia Pacific. Breaking it down further, CIBR invests 74.69% in the United States, 8.25% in India, 7.95% in Israel, 3.95% in France, and 2.76% in Canada. HACK, by comparison, focuses almost exclusively on the Americas, with 96.75% exposure, and only 3.27% in the Asia Pacific region. This means CIBR offers slightly greater international diversification, particularly in emerging markets like India and Israel, while HACK stays more U.S.-centric.

Key Takeaways

These portfolio differences significantly influence long-term growth potential and risk management. Funds with broader international exposure, like CIBR, might benefit from cybersecurity advancements in regions outside the U.S., though they also introduce currency risks and geopolitical factors. On the other hand, HACK's higher small-cap exposure could lead to stronger growth if those smaller companies succeed, but it typically comes with increased volatility. Sector weightings also matter - whether you're investing in pure-play cybersecurity services or hardware and electronics manufacturers, these choices shape the fund's overall risk and return profile.

Which Cybersecurity ETF Is Right for You?

Choosing between HACK, CIBR, and BUG depends on your investment goals, risk tolerance, and perspective on the growth of the cybersecurity industry. With the average cost of a data breach climbing 10% over the past year to $4.88 million, it's clear that cybersecurity remains a critical, high-demand sector.

To make an informed decision, let's break down what makes each ETF distinct:

• CIBR: This fund is a solid choice for long-term investors who prioritize stability, performance, and liquidity. Its broader diversification helps cushion against market downturns, making it a reliable option during challenging periods for the cybersecurity market.
• HACK: If you're looking for concentrated exposure to software and IT within the cybersecurity space, HACK might be your pick. It has consistently performed well in thriving market conditions. With a higher focus on small-cap stocks, this fund leans into emerging players with significant growth potential.
• BUG: For those interested in a more focused portfolio targeting emerging cybersecurity companies, BUG stands out. It invests in firms that generate at least 50% of their revenue from cybersecurity activities. Additionally, its lower expense ratio of 0.51% makes it a cost-efficient option in this niche.

Ultimately, your choice hinges on your specific priorities. If you prefer broader diversification, CIBR offers a balanced approach. For aggressive growth tied to small-cap stocks and software, HACK delivers. And if you're seeking cost-effective exposure to emerging cybersecurity leaders, BUG provides a compelling option. With cybersecurity demand fueled by digitalization, AI-related threats, and government regulations, all three funds are positioned to benefit from the industry's strong profit margins and growth potential.

FAQs

How do I decide which cybersecurity ETF - HACK, CIBR, or BUG - is best for my portfolio?

When comparing HACK, CIBR, and BUG, it's essential to weigh factors like expense ratios, historical performance, and holdings composition. These details reveal the costs involved, past returns, and the specific companies each ETF invests in. It's also wise to examine their sector exposure to ensure they align with your investment goals and risk tolerance.

Beyond that, consider metrics such as the fund's assets under management (AUM), average daily trading volume, and the index it tracks. These indicators can shed light on the ETF's liquidity and overall market focus. Ultimately, the right choice comes down to how well each fund fits into your long-term investment strategy and your perspective on the evolving cybersecurity sector.

How do expense ratios affect the long-term growth of cybersecurity ETFs?

Expense ratios are a key factor to consider when evaluating the long-term performance of cybersecurity ETFs. These ratios represent the annual fees charged for managing the fund, which are deducted from the fund's returns. Over time, higher expense ratios can eat into your overall gains.

When looking at ETFs like HACK, CIBR, and BUG, it's important to balance the expense ratio with other critical aspects, such as past performance, sector exposure, and potential for growth. While a lower expense ratio might seem attractive for long-term investing, it’s equally important to ensure the fund aligns with your financial goals and delivers solid performance.

What are the risks and rewards of investing in small-cap vs. large-cap cybersecurity companies within these ETFs?

When considering cybersecurity ETFs like HACK, CIBR, and BUG, it’s important to weigh the differences between small-cap and large-cap companies. Small-cap companies often have the potential for faster growth. Their agility allows them to adapt quickly and take advantage of new trends in the cybersecurity space. That said, they also tend to be more volatile, which can make their performance unpredictable, especially during market downturns.

In contrast, large-cap companies bring more stability to the table. Their established market position and diversified revenue streams often lead to steady, reliable performance. While their growth might not match the pace of small caps, they can serve as a dependable choice for long-term investors looking to minimize risk. Striking a balance between the two can help create a portfolio that combines growth opportunities with a measure of stability.
