Overview

AskEdgar's general-purpose stock screener. Slice the universe by basic fundamentals (market cap, sector, country), microstructure (float, outstanding, short interest, days to cover, borrow fee), short-term performance windows (1-day through 365-day), and gap/runner counts.

When to use

• Building scanner playbooks (low-float + high short + sub-$5, etc.).
• Powering watchlist filters.
• Sourcing fresh ideas with pending_s1=true for upcoming offerings.

Key parameters

Most filters come in min_* / max_* pairs. A few non-obvious unit notes:

• Decimal vs percentage: gain_*_day filters are percentages (15.0 = 15%). short_float is a decimal (0.15 = 15% of float is short). feerate is a percentage (5.0 = 5% annual borrow cost).
• pending_s1=true — issuers with a pending S-1 (upcoming IPO or follow-on).
• Dropdown filters (industry, sector, country, exchange, state, currency) — fetch valid values via Screener Field Options.

Response highlights

• Identity: ticker, companyname, website, industry, sector, country, exchange, state, currency, cik, cusip, ipodate.
• Market: market_cap, price, averagevolume, today_volume, median_volume_60, vol_change, high_365 / low_365 (365-day price extremes).
• Float: outstanding, float, tradable_float.
• Ownership: insider_percent, affiliate_percent, institutions_percent — decimal, not percentage (0.125 = 12.5%). A 0 is a reported zero; null means unavailable. ownership_source_url links the source document.
• Short: short_interest, short_float, days_to_cover, available, feerate.
• Performance: gain_1_day, gain_2_day, …, gain_365_day.
• Behavior: num_gaps, num_runners, avg_gap, pending_s1, isactivelytrading, isadr.

Notes

• Coverage: audited only for companies under $1B market cap. Larger companies return null for affected fields, with a disclaimer on the response message.
