Research and Portfolio Decisions · Investment Trusts
A decision memo turns scattered research into a clear, testable argument. It should explain what you would own, why the price matters and which evidence would change your mind.
Build a concise evidence record
Start with the product identity, legal form, mandate and intended portfolio role. State the dated price and NAV basis, current discount or premium, borrowing, costs and major exposures. Link each material observation to an official document.
Keep observed facts, calculations and judgments separate. A reported NAV is a fact about a disclosed valuation. Your adjusted asset scenario is a calculation. Believing that a discount may narrow is a judgment requiring reasons, not an established fact.
Include the opposing case
Write the strongest reason not to invest. It might concern valuation uncertainty, persistent costs, portfolio overlap or lack of a credible exit route. Then test a favorable, central and adverse scenario without assigning unsupported probabilities.
For a hypothetical 300p NAV, a 10% discount gives 270p price. If NAV falls to 240p and the discount widens to 20%, price would be 192p. The loss from 270p is about 28.89% before distributions and costs. Would that outcome fit the intended allocation?
Make the conclusion actionable
Record the proposed allocation, implementation constraints and the evidence required before acting. Include the option to wait or reject the investment. A completed memo does not create an obligation to trade.
Finish with monitoring triggers and a review date. The goal is a repeatable reasoning process that can be checked against future evidence, not a promise to predict prices or achieve a particular return.
Try it yourself
Write three statements about a candidate trust and label each fact, calculation or judgment. Why does the label matter?
Show the worked answer
It exposes which claims come from documents, which depend on arithmetic and which depend on assumptions. That makes uncertainty visible and helps identify what new evidence could change the decision.
