VistaShares

This address is how we stay in touch with the professionals who follow our work.

VistaShares delivers innovative Liquid Alternative investment solutions for today's investors. VistaShares ETFs are actively managed by industry and investment experts, offering a number of distinct strategies. Supercycle® Growth Equity ETFs seek exposure to technology-driven economic Supercycles® that the adviser believes may offer long-term growth potential. Target 15® option-income ETFs seek to generate monthly income while complementing a core equity portfolio. Income is not guaranteed and will vary, and the Target 15® name refers to the strategy's objective rather than a guaranteed or promised return. Investing involves risk, including possible loss of principal. There is no guarantee that any investment objective will be achieved, and past performance does not guarantee future results.

From the chip to the substation

It helps to picture an AI data centre as a stack. At the top are the accelerators that do the computation. Beneath them, the memory that holds the models and the data, which has become a constraint of its own. Then the networking that lets thousands of accelerators work as one machine, built from switches, optical links and a great deal of cable.

Below that is the physical plant. Servers sit in racks, racks sit in halls, and the halls need cooling systems that are increasingly built around liquid rather than air, because the newest chips produce more heat in a small space than older designs ever did. Every one of those systems has suppliers with their own capacity limits.

At the bottom of the stack is electricity. Transformers, switchgear, backup generation and the grid connection itself. These are some of the longest lead time items in the whole build, and they sit with industrial manufacturers and utilities that plan in decades rather than product cycles.

Investors who look only at the top of the stack see the most visible part of the spending. The rest of it is spread across sectors that do not carry the word technology in their names.

Stacks like this tend to be refreshed in waves. Each new generation of accelerators can require new networking, new memory, new cooling and sometimes a new building, so the spending arrives in bursts tied to product cycles rather than as a steady stream.

For suppliers lower in the stack, that can mean long quiet stretches followed by sudden demand. For investors, it means the timing of exposure to each layer matters, and that a fund's holdings can move very differently from the headline figures about the trend.

Seen this way, the build-out is less a single industry than a sequence of handoffs between industries, each of which has to deliver on time for the next one to be useful, and each of which can hold up the rest.

That spread is also why funds built around this build-out can differ so widely. Some stay near the top of the stack, others reach all the way down to the grid, and their holdings overlap far less than their names would suggest.

Reading a fund's holdings against this stack, layer by layer, is a quick way to see which of those approaches it has taken.

How exposure to the trend is built

Funds that target AI infrastructure take different approaches, and the differences matter. Some hold mainly the chip and hardware companies at the top of the stack. Others reach down into memory, networking, electrical equipment, construction and utilities. Some screen companies on how much of their revenue comes from the trend; others use broader definitions that include companies for whom it is a small part of the business.

Each choice changes what a fund behaves like. A fund weighted towards a few large chip companies will move with them. A fund spread across the physical supply chain will behave more like a basket of industrial and utility stocks with a common driver. Neither is right; they answer different questions.

Weighting matters as well. A fund weighted by market value tends to concentrate in the largest names. One that caps positions or weights them equally spreads the exposure but takes on more of the smaller, more volatile companies.

The methodology document behind a fund or its index is where these choices are written down, and it is the most useful thing to read before deciding what a fund in this area is actually for.

Rebalancing rules shape exposure too. Indexes in fast-moving areas are reviewed often, and a company whose revenue mix shifts towards or away from the trend can be added or removed at each review. That keeps the fund close to its definition, at the cost of more turnover.

Comparing two funds in this area is therefore less about their names than about their rules, their largest holdings and how much of each would already be owned through a broad market fund.

Fees and trading costs complete the picture. Funds in this area often charge more than broad index funds, and those that rebalance frequently carry trading costs on top, which matter more the longer a position is held.

None of these choices is visible in a fund's name, and two funds with similar names can make opposite choices on every one of them, which is why the documents behind them deserve a careful read.

A fund's fact sheet, holdings list and methodology, read together, usually answer most of these questions in a few minutes.

What the mail from here is about

Mail from this address is about the physical side of artificial intelligence: the chips, memory, networking, buildings, power and cooling that every model runs on. The software gets the attention. The hardware sets the pace, and it is built by a long chain of companies most people have never heard of, many of them far from the technology sector.

The writing here follows that chain from the accelerator down to the substation, because each link has its own lead times, its own constraints and its own cycle, and they rarely line up.

Where they fail to line up is usually where the interesting questions are.
