Welcome to this lesson. Now that you’ve seen an example of a factor and how to create one from data, we’ll give you a closer look at the theory behind these methods by introducing the factor model. This will help you understand the broader context around what you’re doing when you work with factors. After that, we’ ll walk you through some major categories of factors. These are factors such as price volume, fundamentals, sentiment, and alternative factors. Ready, ready. Ready. Ready, Liz? I sure am. Cool. Let’s do this.
