How to Write an Equity Research Report
The format looks intimidating because the professional versions run forty pages and end in a price target. Strip away the sell-side packaging and what remains is a repeatable structure you can build from free, filing-grade data — and the structure, not the page count, is what makes a report credible.
What an equity research report is (and isn't)
An equity research report answers one question in depth: what would a careful person want to know about this company before forming a view on the stock? That means the business model, the financial trajectory, the competitive position, what informed money is doing, how the market prices it, and the best arguments on both sides.
What it is not, necessarily, is a recommendation. Sell-side reports end in ratings and price targets because banks employ registered analysts under a compliance regime built for exactly that. If you're writing for yourself, your team, or clients as an unregistered publisher, the verdict is the part to leave out — both because compensated buy/sell advice edges into regulated investment-adviser territory, and because the verdict is the least durable part of any report. The analysis survives contact with new information; the price target rarely does.
The standard structure
Nearly every professional report is a variation of the same nine sections. Use them in this order — each one sets up the next.
| Section | Answers | Primary source |
|---|---|---|
| 1. Executive summary | The whole report on one page | Written last |
| 2. Business overview | How the company makes money | 10-K Item 1, IR site |
| 3. Financial analysis | Revenue, margins, growth, balance sheet | 10-K/10-Q filings |
| 4. Competitive position | Who it beats, who beats it, and why | Filings, industry sources |
| 5. Ownership signals | What insiders and funds are doing | Form 4, 13F filings |
| 6. Valuation context | How the market prices it vs. peers and history | Market data |
| 7. Bull case | The strongest honest case for the stock | Your synthesis |
| 8. Bear case | The strongest honest case against it | Your synthesis |
| 9. Risks & open questions | What could break either case | 10-K Item 1A, your judgment |
Step 1: Understand the business before the stock
Start with the 10-K's business section and the company's own investor materials, and write the business overview before you look at a single chart. The test of this section: could you explain to a smart friend how a dollar of revenue becomes a dollar of profit — which segment it comes from, who the customer is, what they'd switch to if this company vanished? If you can't, more financial analysis won't save the report, because you won't know which numbers matter.
Step 2: Pull numbers from filings, not headlines
Financial media rounds, annualizes, adjusts, and occasionally mislabels. The filings are the record. Pull at least five fiscal years of revenue, net income, and margins straight from the 10-Ks (SEC EDGAR has every filing, free), so you're describing a trajectory rather than a snapshot. Growth that decelerates from 60% to 20% and growth that accelerates from 5% to 20% both show "20% growth" in a headline — and are opposite stories.
Cite everything
Every figure in the report should carry a source a reader can check — the filing, the transcript, the dataset. This is the single biggest credibility difference between a report and a blog post, and it also keeps you honest: numbers you can't source usually turn out to be numbers someone else rounded.
Step 3: Read the ownership signals
Two free SEC datasets tell you what informed money is actually doing, and they are routinely misread — knowing their limits is most of the skill.
Insider transactions (Form 4). Officers and directors must report their trades within two business days, with the actual transaction price. The signal worth weighting is the open-market purchase (transaction code P) — an insider choosing to pay market price with their own money. Option exercises, grants, and gifts say little, and sales are weak evidence too: insiders sell for compensation and diversification reasons all the time. A cluster of open-market buys is among the most reliable public signals that exists; routine selling is close to noise.
Institutional holdings (13F). Managers over $100M file quarterly holdings. Comparing a fund's latest two filings shows you who initiated, added, trimmed, or exited. Three limits to respect: filings arrive up to 45 days after quarter end, they show quarter-end snapshots (not what the fund did in between), and they never contain purchase prices — any "average entry price" you see attached to a 13F position is an estimate at quarterly prices, and honest reports label it that way.
Step 4: Valuation context, not verdicts
You do not need a discounted-cash-flow model to write a useful valuation section. You need context: what multiple the market pays for this company, how that compares to its own history and to peers, and what assumption about the future is embedded in the price. "Priced at 40× earnings against a peer group at 25×, which implies the market expects growth to hold up longer than the peer set's" is analysis. "Fair value is $180" is a forecast wearing analysis's clothes.
Step 5: Argue both sides
The bull and bear cases are where the report earns its keep, and the discipline is to write both as if you believed them. The bull case is not "the stock could go up" — it's the specific mechanism: what compounds, for how long, and why the market underweights it. The bear case is not a risks list — it's the specific way the thesis breaks. A reader should finish both sections unable to tell which one you personally find more persuasive. If your bear case reads like a formality, you haven't done the work yet.
Five mistakes that sink reports
- Narrating the stock chart. "The stock is up 40% this year" is a fact about sentiment, not about the business. Lead with the business.
- One-year thinking. A single year of financials can't distinguish a trend from an accident. Five years is the minimum for a trajectory.
- Treating insider sales like insider buys. They are not symmetric signals — buys are conviction, sales are usually logistics.
- Copying a 13F position without the lag caveat. The fund you're "following" may have exited six weeks before you read the filing.
- Writing one side. A report with no credible bear case is marketing.

Frequently asked questions
What is an equity research report?
An equity research report is a structured analysis of a single publicly traded company: how the business makes money, how its revenue and margins have trended, its competitive position, who owns the stock and what they've been doing, how the market values it, and the strongest arguments on both sides. Professional versions add a rating and price target; a rigorous report is valuable without either, because the analysis — not the verdict — is what transfers.
What is the standard structure of an equity research report?
The analyst-standard skeleton is: company overview and business model; financial analysis (revenue, margins, growth from the filings); competitive position; ownership signals (insider transactions and institutional holdings); valuation context; the bull case; the bear case; and key risks. An executive summary leads, and every figure carries a citation to its source.
What free data sources can I use for equity research?
SEC EDGAR covers most of it at no cost: 10-K and 10-Q filings for financials, Form 4 filings for insider transactions (which include actual transaction prices), and quarterly 13F filings for institutional holdings. Add the company's investor-relations site for management's own framing, and earnings call transcripts for tone. The main things that cost money are real-time market data, analyst consensus estimates, and screening tools.
How long does it take to write an equity research report?
A focused analyst spends one to three days on a first-coverage report: roughly half reading filings, a quarter on the ownership and valuation work, and a quarter writing. The reading is the irreducible part — most of the errors in fast reports come from quoting a headline number without reading the filing behind it.
Is an equity research report investment advice?
Not inherently. A report that describes the business, its financial trends, and the arguments on both sides is research; advice is telling a specific person what to do with their money. Publishing buy/sell recommendations for compensation moves toward regulated investment-adviser territory, which is why unregistered publishers — including us — keep reports descriptive and carry a not-investment-advice disclaimer.
