Things You Should Know

  • Its brochure says it receives research or services from brokers, but it does not say those perks can shape which broker it picks for you, the firm benefits by not paying for those things, or whether every client benefits or only some. Ask how the firm chooses the broker for your trades and whether perks play any part.Item 12.A.1
  • Its brochure names research or services received from a custodian or broker (soft dollars) as a conflict, but it does not explain what this arrangement tempts the firm to do, say what the firm is paid for it, or say what it can cost you. Ask what the firm receives from the custodian or broker it uses for you, and whether that costs you anything.Items 10, 11, 12.B and 14

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.
