Regulatory Entities & Market Participants
Separate the regulator, the market participant, and the customer protection function before choosing an answer.
How to study the SIE
Learn the concept vocabulary first, then drill products, risks, rules, and prohibited-conduct patterns until they feel automatic.
Core concepts
Concept 1
The SEC is the federal securities regulator, while SROs such as FINRA, MSRB, and CBOE regulate members and markets within their authority.
Exam cue: Name the actor first: regulator, issuer, intermediary, investor, or market utility.
Concept 2
Broker-dealers, investment advisers, issuers, underwriters, market makers, custodians, transfer agents, and clearing agencies all play different market roles.
Exam cue: If the question asks who enforces member conduct, check whether the answer should be FINRA, MSRB, CBOE, or the SEC.
Concept 3
SIPC protects customers if a broker-dealer fails, but it does not protect against market losses.
Exam cue: Do not turn SIPC, FDIC, or the Fed into a general investment-loss insurer.
