Lesson Overview
Make equity market mechanics and efficiency questions concrete.
Level I questions are three-choice multiple choice and are built to reward fast recognition of the relevant rule, relationship, or calculation path. For this lesson, the job is to turn the topic into a repeatable exam move rather than another note to reread.
Mental Model
Order book tiles, spread markers, and index baskets animate trading and information flow.
In the Above MPS system, this sits in Valuation: Focus the method. Use that shape as the memory hook, then connect it to the precise facts in the question stem.
Exam Playbook
- Name the topic before calculating. Decide whether the stem is asking for a definition, direction of effect, classification, or numerical result.
- Apply the rule that changes the answer. Ignore details that do not affect the relationship being tested.
- Check the answer against the common trap. If the tempting choice matches one of the traps below, slow down before locking it in.
High-Yield Map
- Bid-ask spread reflects transaction cost and liquidity.
- Order type controls execution certainty versus price control.
- Efficiency forms differ by which information is already reflected.
Common Traps
- Confusing bid with ask from the trader perspective.
- Assuming market efficiency means prices are always correct.
- Ignoring index weighting method.
Repair Drills
- Label the buyer/seller side of five bid-ask prompts.
- Classify efficiency-form examples by information set.
