Advertise on podcast: Series 7 Exam in the car

Why can you buy a stock and immediately lose money even when its market price hasn’t changed? The answer lies in the bid-ask spread, one of the most important concepts in securities trading. In this episode, we explain how buyers, sellers, and market makers establish prices, why some stocks have wider spreads than others, and how liquidity affects trading costs. We’ll also examine the types of questions the SIE exam uses to test your understanding of bid prices, ask prices, and market execution.

Before you can understand securities transactions, you need to understand the people and firms conducting them. This episode explains the relationship between broker-dealers, brokers, dealers, registered representatives, customers, and regulators. Learn these distinctions early because they form the foundation for many of the rules and scenarios you’ll encounter throughout Series 7 preparation.

The Series 7 is not simply a longer version of the SIE—it tests whether you can apply securities knowledge in situations a registered representative could actually encounter. In this episode, we break down the structure of the exam, what FINRA emphasizes, and how to organize your studying around the areas that matter most. Before memorizing bonds, options, and regulations, understand the test you’re preparing to take.
