Portfolio intelligence: what you own, not what you think you own

Most people hold more of one thing than they realise. Three funds can be the same ten companies; a "diversified" account can rise and fall on one story. This tool reads your own holdings and reports what is actually there — with a plain statement of which positions it could and could not price.

Written by the Capstone Metals research desk. Reviewed by Daniel Kenney, President. Last updated February 2026.

What it reports

Weights and concentration — the share of the account in its largest position, its top five, and a concentration index for the whole portfolio.
Overlapping exposure — pairs that have moved together closely enough that holding both adds less protection than it appears to.
Sector and asset-class grouping — where the money is clustered, using the categories you supply.
Volatility and drawdown — how much the combined portfolio has moved historically, and its worst peak-to-trough fall in the data available.
Scenario ranges — the range of outcomes actually observed in history for a portfolio of that shape. A record of what has happened, not a projection of what will.
What changed — a short written note about the figures above, produced from those figures and forbidden from inventing new ones.

Getting your holdings in

Upload a spreadsheet export or type positions in by hand. A file needs a symbol and a quantity; cost basis, sector and asset class are used if you include them. Column names are matched loosely, and any line that cannot be read is reported back to you individually rather than silently dropped.

Where the honesty line is

We only price what we hold history for. If a holding cannot be priced, it is excluded from every figure and named in a data-gap notice — not estimated, not filled in from a similar asset. Correlation needs enough overlapping sessions to mean anything, and where there aren't enough, the pair is left out and listed. A number we cannot stand behind does not appear.

This is research and education about your holdings. It is not personalised investment advice, not a recommendation to buy or sell any position, and not a forecast. If you want a conversation about your own circumstances, that is what our advisory side is for — call (800) 200-9553.

Where this fits in the wider picture

Market Intelligence is the evidence layer. The wealth-protection side of Capstone is where those findings meet an actual plan — metals, retirement accounts and stewardship of what you already hold.

The education library — money, debt and purchasing power, from first principles.
Gold's place in the world economy — what the historical record does and does not show.
Wealth protection in one place — how metals, advice and entities fit together.
