The iShares U.S. Telecommunications ETF (IYZ) is an exchange-traded fund (ETF) — a fund that trades on an exchange like a stock but holds a diversified basket of securities. Launched in 2000 by iShares, BlackRock's ETF brand, IYZ gives investors a single-ticket way to access the U.S. telecommunications sector, including companies that provide phone, internet, and communication services as well as the equipment that powers those networks. Investors follow it as a targeted way to express a view on connectivity, wireless infrastructure, and the broader digital communications economy.
IYZ's stated investment objective is to track the investment results of an index composed of U.S. equities in the telecommunications sector. The fund currently seeks to follow the Russell 1000 Telecommunications RIC 22.5/45 Capped Index, a benchmark maintained by FTSE Russell. Prior to September 20, 2021, the fund tracked the Dow Jones U.S. Select Telecommunications Index before transitioning to its current benchmark.
The fund is passively managed, meaning it does not rely on active stock selection by a portfolio manager. Instead, it uses a representative sampling strategy, generally investing at least 80% of its assets in the securities of its underlying index or in investments with similar economic characteristics. This approach lets the fund mirror its benchmark's performance without necessarily holding every single constituent.
According to issuer documentation, IYZ typically holds roughly two dozen securities, making it more concentrated than broad-market ETFs. Its exposure spans several sub-industries, including communications equipment, integrated telecommunication services, alternative carriers, wireless services, and cable and satellite providers. The fund is classified as non-diversified, a regulatory designation meaning it can concentrate its assets more heavily in individual holdings than a diversified fund.
IYZ's portfolio holdings reflect the structure of the U.S. telecommunications market. Historically, its largest positions have included networking and equipment leaders such as CSCO (Cisco Systems) and ANET (Arista Networks), alongside major service providers like VZ (Verizon Communications) and T (AT&T). Other notable names have included MSI (Motorola Solutions), TMUS (T-Mobile US), and CMCSA (Comcast).
Because the underlying index blends both telecommunications equipment manufacturers and service operators, IYZ's sector exposure has tilted increasingly toward information technology, reflecting the growing role of networking hardware and optical components in modern connectivity. The fund's top holdings can account for a meaningful share of total assets, so individual company performance can have an outsized influence on returns.
The fund's expense ratio — the annual fee charged to investors for managing the fund — is approximately 0.38% as stated in its prospectus. Holdings and allocations are subject to change and are rebalanced periodically in line with the underlying index.
IYZ attracts attention as a focused vehicle for sector exposure to U.S. telecommunications. Rather than selecting individual telecom stocks, investors can use the fund to gain diversified access to the companies that build and operate the country's communications infrastructure. This theme is tied to long-term trends such as wireless network upgrades, broadband expansion, fiber deployment, and satellite communications.
The ETF can serve several portfolio roles. For investors who believe connectivity demand will keep growing, IYZ offers a convenient way to express that view. It can also be used to add a sector tilt to a broader portfolio, given that dedicated telecom exposure is relatively narrow in many diversified indexes. The fund distributes income on a quarterly basis, though its yield has generally been modest.
Investors should understand several risks before considering IYZ. As a sector-specific, non-diversified fund, it carries concentration risk: its returns can diverge sharply from the broader market and can be heavily influenced by a handful of large holdings. The telecommunications industry is capital-intensive and sensitive to factors such as interest rates, regulation, competition, and technology shifts.
Like all ETFs, IYZ is exposed to tracking error — the difference between the fund's performance and that of its benchmark — as well as standard equity market risk. Its market price may also trade at a slight premium or discount to its net asset value (NAV), the per-share value of the fund's underlying assets. Sector funds, by design, are less diversified than total-market funds and may be more volatile.

The iShares U.S. Telecommunications ETF is one of the longest-standing dedicated telecom ETFs in the market, offering a single, tradable way to access U.S. companies that provide phone, internet, and communication services and the equipment behind them. Its focused, index-based approach makes it a useful reference point for investors tracking the connectivity theme, while its concentration and sector-specific risks make it best understood as a targeted satellite holding rather than a core diversified position.
