Fund Letters

Get fund-letter theses for a company

Returns everything professional investors' letters say about one company: the resolved company block, coverage stats, and every published thesis (newest reporting period first) — each with its stance, conviction, position sizing, thesis/risk/catalyst/valuation summaries, a representative source quote, and a reference to the investor, fund and letter it came from.

Accepts every standard company identifier (companyKey, ticker + exchange/micCode, CUSIP, ISIN, FIGI, CIK, or the Fiscal.ai company identifier). Returns 404 for companies without fund-letter coverage — /v1/fund-letters/companies lists the covered universe.
