See what you actually own inside your ETFs.
A ticker list can hide the exposure that matters. Portfolio X-Ray combines direct positions with the underlying holdings of funds, then rolls the result up across your accounts.
- Direct + fund-derived exposure
- Across connected accounts
- Holding, sector, asset, and currency views
A spreadsheet can miss the overlap.
Owning a stock directly is only part of the picture. The same company may also sit inside broad-market ETFs, sector funds, retirement accounts, and taxable accounts.
Portfolio X-Ray is designed for the question that ordinary brokerage screens rarely answer clearly: how much exposure do I actually have to a company, sector, asset class, or currency?

One look-through view, four useful lenses.
Aerarium Portfolio separates direct exposure from exposure held through funds. You can inspect the result by holding, sector, asset class, or currency without manually rebuilding a workbook.
The goal is visibility, not a recommendation. Aerarium does not tell you what to buy or sell. It makes the exposure visible so you can compare your portfolio with your own rules.
Who it is for
Long-term investors who own ETFs, hold investments across more than one account, or want to understand concentration before changing a portfolio.
What Aerarium does not do
Portfolio X-Ray is an informational monitoring view. Aerarium does not provide investment advice, recommend securities, or place trades.
Questions, answered plainly.
What is ETF look-through?
ETF look-through means identifying the underlying holdings inside funds and combining them with positions you own directly. The result is a clearer estimate of your total exposure.
Does Portfolio X-Ray work across accounts?
Yes. Aerarium Portfolio is designed to roll up supported holdings across connected and manual accounts after applying per-position currency conversion.
Does Aerarium place trades?
No. Brokerage sync is read-only. Aerarium monitors your portfolio and never places trades.
Is the exposure figure investment advice?
No. It is an informational view of your own portfolio data, not a recommendation to buy, sell, or hold any security.
