Your starting question
Can you defend the investment case?
An attractive story needs evidence, business logic and a serious opposing case. Practise reaching a conditional conclusion rather than assembling an unweighted list of advantages and disadvantages.
By the end: Write and defend a balanced investment committee memo, then update it when new evidence arrives.
Try the short baseline. Identify what you need to investigate.
Use diagrams, worked examples and regular choices with feedback.
Work the case in your companion workbook and discuss the trade-offs.
Complete the review and record what changed your mind.

Read the full narration
Welcome to On Judgement. In The Investment Case, we will follow four connected steps. Check the evidence. Then Build the opposing case. Then Test what matters. Then Reach a judgement. You do not need to know the answers before you start. Make an initial choice, read or watch the explanation, and use the feedback to reconsider. A mistake is useful when you can explain what it revealed. Work on the cases independently or discuss them with your club. Keep longer written responses for the parts where you need to make an argument of your own. By the end, use the evidence and calculations to explain a decision and what could change it.
Investing Judgement · Module 3.1
