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.

Terms these notes use
| Overlap | the share of a candidate holding that a portfolio already owns somewhere else, measured by looking through to companies rather than by comparing categories. |
|---|---|
| Concentration | how much of the outcome rests on the largest few positions, which is a different question from how many positions there are. |
| Drift | how far a weight has moved from where it was set, which is what a rebalancing rule acts on and what a calendar ignores between dates. |
| Correlation | how two holdings have moved together, with the caveat that it is measured on the past and tends to rise exactly when it would be most useful for it not to. |
What the mail from here is about
Notes from this address are about how a position behaves inside a book rather than on its own. A holding that looks volatile in isolation can lower the variance of the whole portfolio, and one that looks steady can raise it, and neither fact is visible from a fund page. What decides it is correlation with everything else already held, which changes with the market rather than staying where a factsheet left it.
The practical version of that is sizing. Most of the argument about whether to own something is really an argument about how much, and it is rarely conducted that way. A two percent position and an eight percent position in the same thing are different decisions with different failure modes, and only one of them can ruin a year.
Correlation is also the number most likely to move when it matters least conveniently.
Assets that behaved independently for a decade have a habit of behaving identically for the six weeks a client is paying attention, which is the argument for deciding sizes when nothing is happening.
None of that is a reason to avoid holding things that move. It is a reason to decide how much of them to hold at a moment when the answer is boring, and to write the number down where it can be found again.
