What Is VOX? Vanguard Communication Services Index Fund ETF Shares

The holdings table lists Alphabet twice because the company has two listed share classes, and index funds hold both. Class A at 14.4% plus Class C at 7.8% is 22.2% in a single business. Add Meta Platforms at 20.3% and you have 42.5% of the fund in two companies whose revenues come overwhelmingly from digital advertising. That number determines what owning VOX means. It is not a diversified bet on communications; it is a concentrated position in the two largest online advertising businesses, with telecom and media companies filling the rest. When advertising spending moves, the fund moves with it.

The remaining holdings are not trivial in number, but they are trivial in effect. Disney at 4.4%, Netflix at 4.2%, Verizon at 4.2%, AT&T at 3.9%, Comcast at 3.3%, T-Mobile at 3.0% and Warner Bros Discovery at 2.8% together come to roughly 25.8%, which is still well short of the two advertising platforms above them.

Anyone holding a broad US index fund alongside VOX should check the combined exposure. Meta and Alphabet are already among the largest positions in any US large-cap fund, so adding VOX stacks a sector fund's concentration on top of an index fund's existing weights.

Communication services used to mean telephone companies. Under the Global Industry Classification Standard revision that took effect in 2018, the sector was reconstituted to bring in internet platforms, interactive media and entertainment. Meta, Alphabet, Netflix and Disney moved in from technology and consumer discretionary.

The result is a sector that combines two entirely different business types. Verizon at 4.2%, AT&T at 3.9%, Comcast at 3.3% and T-Mobile at 3.0% are capital-intensive network operators with regulated characteristics, substantial debt and high dividend payouts. Meta, Alphabet and Netflix at 4.2% are asset-light platforms with different economics in every respect.

This is why a communication services fund is difficult to reason about as a single exposure. The sector's aggregate statistics blend businesses that share almost nothing. The 1.07% yield, for instance, is the average of telecoms that distribute heavily and platforms that distribute little, and it describes neither group.

At 0.09% the fee is low for a sector fund, which is Vanguard's usual position and a real advantage in a category where 0.4% and above is common. Cost is one of the few reliable differences between sector funds tracking the same classification.

The case for owning it is narrow but coherent: an investor who wants deliberate overweight exposure to digital advertising and media, and who would rather express that through a sector fund than by buying individual companies. VOX does that at low cost and with the telecom holdings adding a partial counterweight.

It is the wrong tool for a diversified holding, given that two companies are 42.5% of it. It is the wrong tool for income, since the yield blends two incompatible groups. And it is a poor way to gain telecom exposure specifically, because the telecom names are outweighed several times over by the advertising platforms that sit above them.
