Frequently Asked Questions

What does the TransparencyScore measure?

The TransparencyScore measures how clearly and completely an advisor or firm discloses important information in their regulatory filings — things like fees, conflicts of interest, disciplinary history, and business practices. A higher score means better disclosure quality, not better investment performance.

Where does this data come from?

All data comes from public regulatory filings: SEC Form ADV (Parts 1, 2, and 3), FINRA BrokerCheck, and the SEC's Investment Adviser Public Disclosure (IAPD) database. These are official filings that firms and advisors are legally required to submit.

Does a low score mean they're a bad advisor?

Not necessarily. A low score means the firm's public filings are less transparent — they may use vague language about fees, skip details about conflicts, or have a more complex regulatory history. Some excellent advisors work at firms with poor disclosure practices. The score measures the filing, not the person.

How often is this data updated?

Fidelon refreshes data from SEC and FINRA sources on a regular schedule. Form ADV filings are updated annually by firms (with amendments throughout the year), and BrokerCheck data is updated as events are reported. Scores are recalculated after each data refresh.

Can an advisor or firm improve their score?

Yes. Scores are based on what's in public filings. A firm that rewrites its ADV brochure in clearer language, discloses conflicts more specifically, or resolves outstanding regulatory issues will see its score improve at the next refresh. The incentive structure is intentional.
