Private by default
The free check runs in your browser. Holdings are not uploaded, saved, or connected to a brokerage unless you later choose the full Advisor workflow.
Free portfolio check
See where your portfolio is quietly taking too much risk.
Enter holdings or import a simple CSV. Prismiva calculates concentration, effective diversification, sector exposure, and the clearest issues locally in your browser.
Useful, not decorative
See the largest position, top-three weight, effective number of holdings, sector concentration, and prioritized risks instead of a generic pie chart.
A clear next step
Understand which position or exposure deserves review, then optionally connect a read-only brokerage for current events, tax lots, alerts, and ongoing monitoring.
Questions, answered plainly
What to know before you start.
Does Prismiva upload my free Portfolio X-Ray holdings?+
No. The free tool calculates in your browser and does not send the entered holdings to Prismiva.
What is an effective number of holdings?+
It translates concentration into the number of equally weighted positions that would create a similar concentration level.
Is the score investment advice?+
No. It is a concentration and diversification screen, not a recommendation to buy or sell a security.
