Screen 13F holdings by period, ticker, value, and rating; returns each matched fund with only the position(s) that matched Results are wrapped in an envelope: `results` holds up to `limit` funds (max 500), `total_count` is the full server-side match count, and `truncated` says whether paging with `offset` would surface more. `period` accepts '2026-Q2' or an ISO date like '2026-06-30'.

Description, as the server wrote it
Screen insider activity by country, date, value, role, and ticker Screens one market per call, selected by `country`: 'KR' returns individual insider transactions, 'JP' returns 5%+ shareholding reports. The response echoes `country` — switch on it before reading `results`, since the two markets return different record shapes. There is no US coverage; use the 13F screen for US institutional flows.

Description, as the server wrote it
Screen funds by their track record on binary events (any sector) Ranks 13F filers by how their positions resolved through binary events — single-day moves >= ~25%, price-defined, NOT verified cause labels. In biotech these are trial readouts / FDA decisions / buyouts; elsewhere earnings blowups, guidance cuts, M&A. `sector='all'` (default) ranks across everything; `'biotech'` and lowercased sector names ('technology', 'energy', ...) scope the record. `hit_rate` = pops held / events decided; `impact_usd` is dollar-weighted (position value x event return). Always pass `min_events` (>= 5) — a perfect rate on 2 events is noise. Chain with `get_investor_holdings_us` to see what a proven event-caller is buying now, or `screen_investor_sector_exposure_us` to intersect with sector specialists.

Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
Screen investors by sector concentration (e.g. top biotech specialists) Ranks 13F filers by the share of their portfolio in one sector, computed from sector-tagged top-50 holdings. `tier` buckets: specialist (>=60%), heavy (30-60%), tilted (10-30%), minimal (<10%). Interpretation caveats: corporate venture arms (Gilead, Pfizer, GSK) and single-stock endowments (e.g. Lilly Endowment holds only LLY) rank as specialists — pass `min_positions` (e.g. 5) to screen for genuinely diversified sector pickers. Chain with `get_investor_holdings_us` / `get_investor_changes_us` to see what a specialist is buying now.

Description, as the server wrote it
One fund's binary-event track record per sector, with best/worst calls The fund's record of holding names through binary events (price-defined single-day moves — readouts/FDA/buyouts in biotech, earnings/M&A elsewhere; not verified cause labels): one row per sector bucket, the 'all' rollup first, each with hits, blowups, hit rate, dollar-weighted impact, and the five best and worst resolved calls. 404 means the fund had no scored events in the window, not that it is a bad fund.

Why it is in this group
- The name "search_investors_us" says "search": a word for reading.
Description, as the server wrote it
Fuzzy-search investors by name; resolves to CIKs ordered by AUM Case-insensitive partial-name match against the latest-holdings view. Returns the largest funds first so the most likely match is at the top. Use this to resolve a manager name to a CIK before calling investor-axis tools (`get_investor_holdings_us`, `list_investor_periods_us`, `get_investor_changes_us`).

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
