  • Introduction10:45

    In this first lesson, we will review the capital asset pricing model (CAPM) and also learn:

    • Value is what a security should be worth after careful analysis.

    • Price is what the market says it’s worth. 

    • Classical finance (CAPM) says value = price always!!!

    • Behavioral finance say value = price generally, but not always.

    In this lesson, we begin to question the three assumptions of efficient markets. Here, we learn (and question) that:

    1. Security prices should respond quickly and accurately to new information.

    3. All simulated trading strategies should fail over time.
