Making the Case in Five Moves: Writing Investment Committee Papers That Drive Decisions

An investment committee memo is not a repository for every model, meeting note and spreadsheet tab. It is a decision document. In UK buy-side and sell-side teams alike, the analyst who can compress complex work into a clear recommendation is more useful than the one who simply supplies more pages. The five-part structure below is designed to make the paper readable, defensible and actionable.

Start with the decision

Before writing, identify the decision the committee is being asked to make. Is it to initiate, add, trim, exit, approve a valuation or challenge an assumption? A memo that does not state the decision early forces readers to infer it. State it in the opening paragraph, then use the five sections to support it.

Part 1: Thesis

The thesis should fit into one or two sentences and contain a claim that can be tested. It should explain what the market is missing, why the opportunity exists and why now. A common weakness is to describe the company rather than the investment case.

Before: 'The company has a strong market position and an experienced management team.'

After: 'We recommend initiating a position because the market is capitalising the division at a cyclical trough multiple while its contract backlog and pricing power support mid-single-digit margin expansion over the next two years.'

The second version gives the committee a proposition to debate. It also makes the rest of the memo easier to write because valuation, catalysts and risks can be linked directly to the claim.

Part 2: Valuation

Valuation should anchor the thesis, not decorate it. Show the key assumptions, the base case and at least one downside case. For UK equities, that may mean comparing free cash flow yield with gilt yields, using local and international comparables, or testing a reverse DCF to show what the current price implies. Be explicit about what is priced in.

A concise table is usually better than a long narrative. Include the valuation method, the key inputs, the implied upside or downside and a sensitivity range. If the recommendation depends on a re-rating rather than earnings growth, say so. Committees are rightly sceptical of papers that hide a heroic multiple assumption inside a detailed model.

Part 3: Catalysts

Catalysts convert a thesis from an opinion into a timetable. List the events that could cause the market to recognise the mispricing: results, guidance, capital allocation decisions, regulatory outcomes, disposals or management changes. For each, give a date or window, a probability range and the metric that will show whether the catalyst has worked.

Avoid vague phrases such as 'improving sentiment'. A catalyst should be observable. If there is no identifiable catalyst, the memo should say that the thesis is a slow-burn value case and set a review horizon accordingly.

Part 4: Risks

Risks should be written before the recommendation is finalised, not added as a compliance afterthought. Use a pre-mortem: assume the investment has failed two years from now and explain why. Separate thesis risks from portfolio risks. Thesis risks include demand weakness, margin pressure, governance concerns or balance-sheet stress. Portfolio risks include correlation with existing holdings, sector limits, liquidity and currency exposure.

Include what would change your mind. This is one of the most useful sentences in any memo because it gives the committee a monitoring framework. A risk section that lists generic uncertainties without ranking them is unlikely to reassure readers.

Part 5: Recommendation

End with a clear action. Specify direction, sizing, entry discipline and review triggers. If the recommendation is conditional, state the condition. If the committee needs to choose between options, set them out briefly with a preferred route.

Before: 'The stock looks attractive and we would be comfortable owning it.'

After: 'We recommend initiating a 1.0% position, funded from the existing cash balance, with a further 0.5% add on confirmation of backlog conversion at the interim results. We would review the thesis if gross margin falls below 32% or if the contract backlog declines for two consecutive quarters.'

The second version is a decision. It gives the committee something to approve, amend or reject.

Making the memo readable

Keep the main paper to two pages where possible and place detailed models in an appendix. Use headings, short paragraphs and tables. Put the recommendation at the top and repeat it at the end. Number the pages and date the version so that committee members know they are reading the latest draft.

Buy-side analysts should emphasise portfolio impact, position sizing and correlation with existing holdings. Sell-side analysts should emphasise the evidence base, the variant perception and the risks to the call. Both should avoid burying the conclusion.

A good investment committee memo does not prove how much work was done. It helps a group of busy professionals make a better decision. The five-part structure is a simple discipline for achieving that.
