Disciplinary Rankings by State
How do financial firm disciplinary rates compare across US states? Some states have higher concentrations of firms with clean records, while others have higher average disclosure rates. Geographic patterns may reflect differences in state-level regulatory enforcement, industry composition, and business practices.
Cleanest states by Grade-A share
Among the 33 states and territories with at least 10 registered firms (a floor that keeps a tiny sample from swinging to an extreme rate), ranked by the share of firms earning a clean size-normalized Grade A.

Highest disclosure rate per firm
Same 33-state eligible set, ranked by average disclosures per firm, a rate, not a raw volume, so a state is not penalized simply for hosting more firms. A higher rate reflects more disclosures per registered firm, not necessarily worse individual firms; enforcement intensity and reporting practices vary by state.

State-level analysis of broker-dealer disciplinary data reveals meaningful patterns. States with strong state securities regulators and active enforcement tend to have lower firm-level disclosure rates, as poor actors are removed more quickly. States that are home to major financial centers may have higher absolute numbers of disclosures but comparable or lower disclosure rates relative to their footprint.
Investors relocating between states or working with out-of-state advisors should understand that regulatory oversight varies. Some states have well-funded securities divisions that supplement FINRA and SEC oversight, while others rely more heavily on federal regulators. Checking both the firm's national BrokerCheck record and your state securities regulator's database provides the most complete picture.
How Firms Are Graded
Each firm receives a grade (A through F) based on disclosure counts normalized by firm size and years in operation. Disclosures include customer complaints, regulatory actions, arbitration awards, criminal matters, and civil judgments. We weight recent disclosures (last 5 years) more heavily than older ones, since historical issues at a firm that has since reformed its practices carry less predictive weight for today's investor.
Grade A firms have essentially clean records, few or no recent disclosures, and those present are typically routine customer complaints resolved in the firm's favor. Grade F firms have a pattern of serious, recent disclosures that warrant investigator caution.
Why State Matters
State securities regulators are a critical layer of investor protection that many investors overlook. A state regulator can revoke a broker's state registration independently of FINRA, pursue restitution for affected state residents, and enforce laws that go beyond federal minimums. Strong-enforcement states tend to include New York, Massachusetts, California, and Texas. States with limited resources or staffing may rely heavily on federal cooperation.
Before working with any advisor, check: (1) FINRA BrokerCheck at brokercheck.finra.org for firm and representative history; (2) SEC Investment Adviser Public Disclosure (IAPD) for investment advisor registration; (3) your state securities regulator, find yours via the North American Securities Administrators Association (NASAA) contact directory.
Limitations of State-Level Comparisons
State rankings have caveats. Large states with major financial hubs (NY, CA, IL) naturally host firms of all quality tiers. A state with few firms may look "clean" simply because the sample is small. States with active regulatory enforcement may appear to have more disclosures because issues are surfaced, not because quality is worse. Always look at individual firm records rather than judging by state aggregates alone.
