Writing the One-Pager

The capstone chapter walked through building a full, real pitch. In practice, almost nobody — a portfolio manager, a hiring interviewer, a professor — reads the full model and write-up first. They read a one-pager: a single-page summary that has to earn the reader's attention to go any deeper at all. This deep dive is about writing that page well.

The one-pager's actual job

A one-pager isn't a shorter version of the full pitch — it's a different document with a different job: convince a busy, skeptical reader in under two minutes that this idea is worth their time to actually dig into. Every sentence is competing with the reader's instinct to move on to the next pitch in their inbox. That constraint should shape the writing, not just the length.

The structure that actually works

• Header line: company, ticker, current price, your rating and target price, all in one line — a reader should be able to grasp the entire numerical thesis before reading a single sentence of prose.
• The thesis, in 2-3 sentences, up front: not buried after paragraphs of company background. Lead with the actual argument — "the market is underpricing X because of Y" (the same specific, checkable-claim discipline from the capstone chapter) — not a general description of what the company does, which the reader likely already half-knows or can look up in seconds.
• 3-4 supporting points, each one line: the strongest, most specific evidence for the thesis — a real number, a real catalyst, a real comparison — not vague adjectives ("strong management," "great brand") that could apply to almost any company.
• Valuation, one line: your target price, the methodology behind it, and the implied upside/downside — "$85 target (12x FY+1 EBITDA, in line with peer average), 22% upside from $70" is a real, checkable sentence; "the stock is undervalued" is not.
• The bear case, genuinely stated, not strawmanned: one or two real sentences on the strongest case against your thesis — exactly the honesty test from the capstone chapter, compressed to its sharpest form. A one-pager with no real bear case reads as either naive or dishonest to an experienced reader, and is a fast way to lose credibility.
• Catalyst and timeline: what specific event, and roughly when, should cause the market to re-price toward your view.

What separates a good one-pager from a mediocre one

The mediocre version describes the company. The good version argues a specific case, with numbers doing the work instead of adjectives. Read your own draft and cross out every sentence that's purely descriptive rather than argumentative — "Company X operates in the widget industry" tells the reader nothing they couldn't get from a ticker lookup. "Company X's new product line, launching in Q2, addresses a segment its two largest competitors have structurally underinvested in" is doing real, specific argumentative work.

Practice this directly

Take the full pitch you built in the capstone chapter — or one of the ten real pitches in My Analysis — and force yourself to compress it to exactly one page, following this structure. The compression itself is the exercise: it forces you to identify which parts of your own thinking are actually load-bearing for the thesis, and which were just padding. That's a genuinely different skill from building the underlying model, and arguably the more commercially useful one — nobody gets asked to present a full 40-tab model out loud, but everyone eventually has to explain their idea in two minutes or less.
