# Screen Companies by Positioning

> Filter companies by short interest, days to cover, net insider buying or selling, insider ownership, CEO pay, and Taiwan foreign-ownership and monthly-revenue axes.

Screening companies by positioning filters on who is long, short, buying and selling: exchange-reported short interest, open-market insider activity from SEC Form 4, the directors-and-officers stake and CEO pay from the proxy statement, and the Taiwan-specific foreign-ownership and revenue axes. Each measure carries its own coverage boundary, stated below, because filtering on any of them silently drops every company the measure does not reach.

## The Short-Interest Filters

<ParamField query="short_percent_float_gte" type="number">
  Short interest as a percent of float; `_lte` sets the ceiling. **US-only**, settled twice a month — see [Short Interest](/ownership/short-interest).
</ParamField>

<ParamField query="days_to_cover_gte" type="number">
  Short interest over average daily volume.
</ParamField>

## The Insider Filters

<ParamField query="insider_net_90d" type="string">
  `buying` or `selling`: net **open-market** Form 4 activity over 90 days, US filers. Counts purchase and sale codes only — grants, option exercises and tax withholding are compensation mechanics, not decisions, and are deliberately excluded. See [Insider Trades](/ownership/insider-trades).
</ParamField>

<ParamField query="insider_ownership_pct_gte" type="number">
  The directors-and-officers group stake from the latest proxy, `0–100`; `_lte` sets the ceiling. Null for dual-class filers whose proxy states it per share class — those never match. See [Proxy Ownership](/ownership/proxy-ownership).
</ParamField>

<ParamField query="ceo_total_comp_gte" type="number">
  Latest-proxy CEO total compensation floor in USD; `_lte` sets the ceiling. Annual, US proxy filers. See [Executive Compensation](/ownership/executive-compensation).
</ParamField>

## The Taiwan Filters

<ParamField query="tw_foreign_held_pct_gte" type="number">
  Foreign ownership percent of a Taiwan listing, `0–100`; `_lte` sets the ceiling. See [Taiwan Foreign Ownership](/international/taiwan-foreign-ownership).
</ParamField>

<ParamField query="tw_revenue_yoy_pct_gte" type="number">
  Latest monthly revenue YoY percent — Taiwan's monthly revenue disclosure, an axis that exists in no other market. `_lte` sets the ceiling.
</ParamField>

## Every Positioning Filter Is Also a Coverage Filter

Short interest is US-only and twice-monthly. Insider activity is US Form 4. Proxy measures cover US proxy filers, annually. The `tw_*` columns are Taiwan listings. Filtering on any of these silently drops every company the dimension does not reach; the response's `coverage` block states each boundary, and the free facets endpoint counts each population.
