Where independent voices converge into a tradeable signal.

Estuary reads a curated set of finance writers — value blogs, macro letters, sector specialists — and extracts the picks they actually make: ticker, direction, conviction, horizon. For each pick we trace forward returns at 1, 5, 21, 63, and 252 trading days against an SPY benchmark. The result is a per-writer track record you can rank, weight, and act on.

The harder signal is what happens when independent writers converge. When two or more sources with non-trivial individual records make the same call within a window, that's a tradeable input regardless of any single source. Estuary surfaces those clusters in a daily JSON brief that flows into Stalker as macro context.

Sister project to Headwater — same pipeline shape, different question. Headwater synthesizes your personal subscriptions for a private digest; Estuary attributes a curated public corpus for cross-source convergence.
