IYZ: Stable Cash Flows From Telecom Carriers And Fiber Expansion

IYZ is best understood as a concentrated telecom sleeve, not a broad communications fund. With a small holding count and a heavy tilt toward a few incumbents, the ETFโ€™s outcome is driven less by the sector label than by how its index weights network operators versus equipment and infrastructure suppliers. That makes the fundโ€™s composition important for investors who want telecom exposure without accidentally broadening into large internet platforms or media names.

For ETF investors, the cost question matters as much as the thesis. A higher expense ratio can be harder to justify in a niche segment where the portfolio already carries meaningful concentration. In addition, funds centered on a relatively narrow industry may be more sensitive to spread costs and market depth when conditions shift, so implementation quality is worth checking alongside the headline fee.

In portfolio terms, IYZ is a defensive-style sector allocation with a specific trade-off. It can complement growth-heavy holdings by adding an income-oriented, cash-flow-driven business model, but it should still be treated as a satellite position rather than a core diversifier. Rebalancing discipline is important here: telecom exposure can drift from โ€œstableโ€ to โ€œover-committedโ€ if an investor lets one sector carry too much of the portfolio.


Investment Thesis

iShares U.S. Telecommunications ETF (IYZ) is a buy due to the strength of its top-weighted holdings and their durable cash flow profiles. While these established telecommunications companies will likely see less impressiveย growth than some top holdings of peer funds, the networks of IYZโ€™s top holdings are mature with stable customer bases. Additionally, these same networks are capitalizing on growth in hyperscaler demand and AI infrastructure, driving IYZ to offer a blend between capital appreciation and dividend income potential.

iShares U.S. Telecommunications ETF: Overview and Compared ETFs

IYZ is a passive ETF that tracks an index that provides investors exposure to U.S. phone, internet, andย communication services companies. With its inception in 2000, the fund has 21 holdings and $1.1B in AUM. Within the communications sector, IYZ captures communications equipment (47.6% weight), integrated telecommunications services (25.4% weight), and alternative carriers (11.6% weight).

For comparison purposes, other funds examined are Vanguard Communication Services Index Fund ETF (VOX) and State Street SPDR S&P Telecom ETF (XTL). VOX is aย passive fundย that captures holdings focused on telephone, data transmission, cellular, and wireless communications services. Iย wrote on VOXย over a year ago and rated the fund a buy. XTL seeks to track aย modified equal weight indexย focusing mostly communications equipment (57% weight) and alternative carriers (20% weight). Due to its index construction, the fund has the most diversified blend of large, mid, and small-cap holdings.

IYZ Compared: Performance, Expense Ratio, and Dividend Yield

IYZ has a 10-year average annual return of 5.05%. As a result, the iShares fund has significantly underperformed both VOX and XTL with 10-year average annual returns of 9.55% and 16.54%, respectively. This underperformance can largely be attributed to the fact that IYZ has maintained heavy concentration on large, established telecommunications providers that have seen slow growth. However, for reasons I discuss in this article I believe that these top holdings are positioned for a solid rebound.

Beyond performance, a key drawback for IYZ is its fees. With an expense ratio of 0.38%, IYZ has the highest fees compared to peer funds. However, a redeeming quality is its dividend yield, which is the highest at 1.69%. While IYZโ€™s 5-year dividend CAGR has been the lowest, its top holdings demonstrate income growth potential which I believe will reverse this declining dividend trend.

IYZ Holdings and Its Competitive Advantages

Due to the differences in each fundโ€™s tracked index, top holdings differ significantly. IYZโ€™s top holdings are Cisco (CSCO), Verizon (VZ), AT&T (T), Iridium (IRDM), and Arista Networks (ANET). VOXโ€™s top holdings are Meta Platforms (META), Alphabet Class A (GOOGL), Alphabet Class C (GOOG), and Walt Disney (DIS). XTL unique top holdings are Extreme Networks (EXTR), Viavi Solutions (VIAV), and Viasat (VSAT).

IYZโ€™s top three holdings comprise almost 50% weight for the fund. Additionally, given the fundโ€™s track index, these top companies are likely to maintain top positions for the foreseeable future. Each of these top holdings have distinct strengths driving a positive outlook for IYZ overall.

Cisco: Capitalizing on Massive Hyperscaler Growth

The first key holding for IYZ is Cisco Systems, an infrastructure company thatย strives to unifyย automation, AI, and security. Cisco has positioned itself as a key provider in hyperscaler AI infrastructure and AI connectivity. For instance, Cisco generated nearlyย $2B in hyperscaler AIย orders late last year and is expecting to see $4B in hyperscaler-related revenue in FY26. These hyperscalers are experiencing strong growth driven byย large-scale data center expansionย required by companies like Google and Amazon (Original Post>

This data center growth has driven an overall 9.2% YoY revenue growth for Cisco. The company has also been profitable with 19.7% net income margin. As a result of its growth in supplying hyperscalers and AI connectivity, Cisco has seen a one-year share price rise of 81%. CSCOโ€™s valuation is a bit stretched with a forward P/E of 28.0x. Looking forward, hyperscaler-owned data capacity and infrastructure is expected toย reach about 60%ย of total critical worldwide IT load by 2030. This is up significantly from just 10% in 2018. However, Cisco reduces risk through diversification in other products and services. Its total product order, excluding hyperscalers, roseย 19% YoY last quarter. Therefore, Cisco represents the first strong holding for IYZ.

Verizon: Expanding Fiber Network and Healthy Dividend Yield

The second strong factor for IYZ is Verizon, an integrated telecommunications company that has traditionally seen muted growth over the past decade. This has been seen by its YoY revenue growth of just 2.85%. However, the carrier is seeing strong recent returns including theย highest-ever adjusted EBITDAย last quarter. Verizon also has been able to achieve solid profitability with a 12.5% net income margin. Over the past five years, Verizonโ€™s share price has declined 18.7%. Verizonโ€™s valuation is also attractive compared to the rest of the communications sector with a forward P/E of just 9.2x.

Looking forward, Verizon will maintain its competitiveness against peers like AT&T and T-Mobile US (TMUS) through its strategic acquisitions and expanding fiber internet network. This expansion includes itsย acquisition of Frontier Communicationsย in February, expanding its fiber network to 31 states. Verizon also provides a solid income component to IYZ through its high 6.2% forward dividend yield. Given its profitability and healthy 57.6% dividend payout ratio, Verizon will remain a key factor for IYZโ€™s overall dividend yield.

AT&T: Beat Down and Ready for Rebound

The third difference is AT&T, another telecommunications provider. AT&T, like Verizon, has seen a string of unimpressive fundamental metrics. These include a YoY revenue growth of just 2.9%. Additionally, AT&Tโ€™s free cash flow has declined for three consecutive quarters while the companyโ€™s net debt has reached a recent high. As a result, AT&Tโ€™s share price has dropped by over 20% in the last year. However, there is room for optimism. AT&T hasย increased its convergence rate, which is the percentage of customers that subscribe to both AT&T wireless and broadband home internet services. This metric has slowly increased in recent years up to 42%. Furthermore, AT&T hitย 30 million fiber locationsย last year, halfway to its goal of 60 million fiber locations by 2030.

As a result of its share price decline, AT&T is also attractively valued. With a forward P/E of 9.5x, AT&Tโ€™s valuation is 56% lower than the communication sectorโ€™s median P/E ratio. With its growing fiber network, the company expects free cash flow to steadily rebound, hitting overย $18B in 2026ย and $21B in 2028. While AT&T faces fierce competition with other providers like Verizon, AT&Tโ€™s competitive advantage lies in itsย more affordableย service plans and more widespread 5G coverage. These factors will likely perpetuate AT&Tโ€™s strong dividend yield which currently stands at over 5%.

Current Valuation and Performance Outlook

Over the past year, XTL has seen significant outperformance compared to IYZ due to its diversified blend of holdings that include amplified exposure to AI infrastructure and data centers. As a result, XTL includes companies like VIAVI Solutions and Extreme Networks that have seen one-year returns of 405% and 89%, respectively. However, these same holdings have negative or low net income margins and rely on significant earnings growth. Should these companies disappoint in future earnings, they will likely see steep declines.

In contrast, IYZโ€™s top holdings demonstrate stable cash flows with steady growth. IYZโ€™s overall valuation is roughly on par with peers with a P/E ratio of 18.2x. All funds examined in the communications sector are more attractively valued than the broader U.S. market as measured by theย S&P 500 Indexโ€™s P/E ratioย of 32x. While peer funds like XTL may see explosive returns compared to IYZ, I believe the iShares fund still warrants an overall buy ratio due to its stable income streams from subscription plans and growing networks. For this reason, I believe IYZ may underperform XTL and VOX in the short term but offer stronger and more stable returns in the long term.

Risks to Investors

IYZ has inherent risk by being concentrated in the communications sector. IYZโ€™s holdings like Cisco are benefiting from growth in other sectors such as information technology. Another key risk is competitive pressure within residential and commercial telecommunications providers. After T-Mobileย acquired Mint Mobileย in 2023, T-Mobileโ€™s market share surpassed both Verizon and AT&T.

Given a U.S. population growth ofย only 0.5% annuallyย over the past few years, these telecommunications companies must compete for roughly the same consumer base, at least within the United States. The competitive environment will perpetuate the slow, but steady growth for top holdings like Verizon and AT&T. As a result of these risk factors, investors in IYZ may face short-term opportunity costs compared to both peer funds and the broader U.S. market.

Concluding Summary

IYZ has traditionally underperformed multiple peer funds due to its concentration on established telecommunications providers. However, these top holdings offer stable cash flows while investing in growing networks. Therefore, while IYZ may see less impressive short-term returns, I believe IYZ offers investors a balanced mix of capital appreciation and income potential over the long run.
