Convenient, perhaps, but certainly confusing. The home page for BrokerCheck states that "BrokerCheck can tell you if a broker or brokerage firm is registered." And then, with seeming sleight of hand, it states that "individuals and firms can be registered as brokers or investment advisors — or both. Individuals with these designations have particular knowledge and take on legal responsibilities. Individuals and firms must be registered with FINRA (for brokers), the SEC (for certain investment advisors) and in those states where required by law."
Confused? I don't blame you.
But that confusion isn't isolated. The same page espouses that BrokerCheck can tell you about what a broker or brokerage firm is "able to do." And then, "brokers and investment advisors are qualified to perform certain tasks for clients, based on the exams they have passed and state licenses they hold. Individuals and firms must register in each state where they have customers." The former is unclear; the latter is untrue for investment advisors.
When you're looking into an advisor's background, keep in mind that it's not unusual for him or her to have some type of involvement with client, employment, legal or regulatory disputes, so these disclosures alone are not necessarily reason to set an advisor aside.
Some advisors find themselves embroiled in quite protracted matters but come out better on the other side of an ordeal. Look for patterns that show customer dissatisfaction — these could point to real issues with their performance or service.
