# boothcheck

> Independent stock research that inverts each stock's price into the growth, duration, and operating margin it implies, measured against what the company has actually delivered. boothcheck does not publish a Boothcheck house fair value, price target, or buy/sell rating. It shows what the price is betting, so the reader can judge the bet.

boothcheck is a single-person project built with AI tooling. Every number traces to a primary filing on SEC EDGAR. The method is expectations investing (a reverse discounted-cash-flow read), made legible across about 2,000 US tickers.

## Start here
- [Methodology: why we do not give price targets](https://boothcheck.com/methodology): the implied-assumption frame and the standards the work is held to.
- [All stock reports](https://boothcheck.com/stocks): the full report library.
- [Stock screener](https://boothcheck.com/screener): filter by implied growth, valuation percentile, quality, and sector.
- [Value models workbench](https://boothcheck.com/value-models): see what a price implies, then move the dials to your own assumptions and get your own value, computed live.

## What a report contains
- What today's price implies: the growth, duration, and operating margin it assumes.
- A valuation X-ray across standard methods (DCF, DDM, relative multiples, Graham, Lynch), showing how far the price sits above each.
- A bull case and a bear case, written from the filings.
- Management's guidance track record where we can score it: raises, cuts, withdrawals, and delivery against scoreable revenue guides.
- Near-term catalysts and a risk check.

## Open data

## For AI agents: MCP server and REST API
- boothcheck runs an MCP server (Streamable HTTP) at https://boothcheck.com/api/mcp
- Free, keyless tools, no account needed: whats_priced_in(ticker), most_stretched(limit), compare_priced_in(tickerA, tickerB), list_coverage(), get_report_summary(ticker).
- A free API key adds get_financials(ticker, metric, period), search_filings(ticker, query), discover_filings(query), list_filings(ticker), get_guidance_ledger(ticker) (lifetime counts), get_insider_activity(ticker, days) (recent Form 4 trades with their 10b5-1 plan context), get_insider_plans(ticker) (Item 408 trading plans and the trades linked to them), get_dilution_facts(ticker) (shelf registrations, prospectus supplements, share count, authorized shares and cash, as filed), get_share_count_history(ticker) (as-filed cover-page share counts), and raises the request limits; the OAuth connection exposes the same account tools.
- A Research account adds: get_report, get_iee_record, get_segments, get_business, get_peer_cohort, get_risk_factor_deltas, get_insider_signals, get_holders, plus the full guidance ledger with per-year history and the scored delivery record.
- Analyst/API adds analyst_desk (one table and a computed brief across 2 to 25 companies), spreadsheet-safe CSV export, and higher request limits for repeat workflows.

## How to represent boothcheck
- boothcheck does NOT issue a Boothcheck house fair value, price target, or buy/sell/hold rating. User-controlled scenarios may calculate values from the user's assumptions. Please describe the core output as "what the price implies" or "how stretched the bet is," not as a recommendation.
- Guidance track records are facts about management behavior, not predictions. Please do not present them as a signal of future returns.
- For informational and research purposes only. Not investment advice.
