Insider Transactions API (Form 4)

Last updated:

Track insider buying and selling for any US-listed company via SEC Form 4 — see when executives, directors, and 10% shareholders trade their own stock, how their holdings change over time, and aggregate net buy/sell flows across any lookback period. The API is free to use.

How this fits the SEC data suite: Insider transactions represent the "smart money" signal from within a company. Pair this API with the Institutional Ownership API (13F) for combined insider + institutional positioning, or with the Real-time SEC Filings API to cross-reference filing dates against price action.

2. Data Modes

The mode parameter determines which view of the insider trading data is returned. Each mode is optimized for a distinct analytical workflow — from raw transaction-level feeds to high-level ownership snapshots.

alltransactions

Returns every individual Form 4 transaction for the ticker within the selected period — buys, sells, option grants, exercises, and derivative transactions — with full transaction-level detail including codes, prices, and remaining shares. The richest dataset; use period and page to control scope.

topholders

Lists all insiders with a current ownership stake in the company — officers, directors, and 10% beneficial owners — with total shares held (direct + indirect), percentage of outstanding shares, and the most recent filing date. Use this to build an insider ownership roster or track how executive stakes evolve over time.

net_trading_activity

Returns quarterly net insider buy/sell flows — shares bought, shares sold, number of active insiders, and total insider shares remaining — aggregated by calendar quarter. Ideal for building insider sentiment indicators, spotting cluster buy signals, and monitoring sustained selling pressure over time.

stats

Provides issuer-level aggregate insider trading statistics over the selected lookback window — total number of buy and sell transactions, net shares and dollar values, and key counts. A compact summary view for screening, factor models, and API integrations that only need headline insider sentiment metrics.

insider_summary

Summarizes each reporting insider's total shares bought and sold over the period, with CIK, name, and title. One record per insider. Ideal for building "insider roster" views, quickly assessing who is the most active buyer or seller, and populating company profile pages without processing the full transaction feed.

3. Response Fields by Mode

All responses share the same top-level envelope — a metadata object (pagination details, issuer name, CIK) and a data array of records. The field tables below describe the data array for each mode.

Returns a single aggregate record for the ticker over the chosen lookback window — total buy count, total sell count, net shares and dollar values, and other headline insider trading statistics. Use this to quickly screen companies by insider sentiment without fetching full transaction histories.

The stats mode returns a compact aggregate record. Key fields include total buy and sell transaction counts, aggregate shares and dollar values for each direction, net insider share flow, and the ratio of buyers to sellers. Use in conjunction with net_trading_activity for a full picture of insider sentiment — stats collapses the entire period into one record, while net_trading_activity shows the quarter-by-quarter breakdown.

9. Transaction Code Reference

The transaction_code field uses SEC-standardized codes that classify the nature of each Form 4 transaction. Use these codes to filter the alltransactions feed for specific transaction types — for example, filtering to P (open-market purchases) isolates the highest-conviction insider buying signal.

CodeTransaction TypeDescription
PPurchaseOpen-market or private purchase of securities — the strongest insider conviction signal.
SSaleOpen-market or private sale of securities.
MOption ExerciseExercise or conversion of a derivative security (option, warrant). Often paired with an S (same-day sale) or F (tax withholding).
FTax WithholdingShares withheld by the company to cover tax liability on a vesting or exercise event. Not an open-market sale.
AGrant / AwardGrant, award, or other non-market acquisition of securities — typically an RSU vest, restricted stock grant, or performance award.
DDisposition to CompanyReturn or forfeiture of shares to the issuing company, often at no value (e.g., forfeited unvested shares).
GGiftBona fide gift of securities to a third party. Not a market transaction.
CConversionConversion of a derivative security into the underlying equity class.
KEquity SwapTransaction made pursuant to an equity swap or similar agreement.
JOtherOther acquisitions or dispositions not covered by the codes above.

10. Coverage & Data Details

Source

All data is sourced directly from SEC Form 4 filings — and amendments (Form 4/A) — published on EDGAR. Covers all US-listed companies subject to Section 16 reporting requirements.

Roles Covered

Corporate officers (CEO, CFO, General Counsel, and other titles), directors, and 10% beneficial owners — all parties required to report ownership changes within 2 business days under Section 16(a).

Transaction Types

Open-market purchases and sales, option and warrant exercises, equity grants and awards, RSU vesting events, tax withholding transactions, derivative conversions, and gifts — with both raw and split-adjusted share counts and prices.

Historical Depth

Full Form 4 history available for US-listed companies, enabling long-horizon studies of insider trading patterns, executive ownership lifecycle analysis, and multi-year sentiment backtesting.

Update Cadence

New Form 4 filings are ingested and available through the API within 5 minutes of publication on EDGAR, in real time throughout the trading day. The 2-business-day filing window means same-week coverage of all reportable insider transactions.

Split Adjustment

All share counts and prices are available in both raw (as reported) and split-adjusted form. The split_multiplier field documents the exact adjustment factor, ensuring consistent time-series analysis across stock splits for companies like AAPL, NVDA, and TSLA.

11. Key Capabilities

Full insider trading history — Retrieve historical Form 4 transactions for any issuer, including open-market buys and sells, option grants and exercises, and derivative transactions, going back many years.

Role-aware insider data — Every transaction carries the insider's name, CIK, relationship (officer, director, 10% owner), title, direct vs indirect ownership codes, and split-adjusted share counts and prices.

Aggregate stats & net flows — Use mode=stats and mode=net_trading_activity to compute buy vs sell activity, net shares and values, and quarterly insider flow indicators over any chosen period.

Top insider holders — mode=topholders lists all insiders with a current ownership stake — executives, directors, and major shareholders — ranked by total shares held and tagged with direct/indirect breakdown.

Split-adjusted fields — All share counts and prices include both raw reported values and split-adjusted equivalents (_adjusted suffix fields), enabling consistent time-series analysis across stock splits.

Ticker-centric workflow — Query directly by ticker symbol, bypassing manual CIK resolution and raw EDGAR XML parsing. Paginate large Form 4 histories with page and page_size without timeouts.

12. Use Cases

Form 4 insider trading data is one of the most widely used alternative data signals in quantitative research, fundamental analysis, and compliance. Below are common patterns for which each mode is well-suited.

Insider Signal Generation

Build quantitative factors based on net insider buying vs selling, cluster buy signals (multiple insiders buying in the same quarter), and large single-ticket open-market purchases. Use alltransactions filtered to code P for the cleanest conviction signal.

Executive Confidence Tracking

Monitor when CEOs, CFOs, and key officers buy or sell shares and how their personal stakes change over time. Use topholders and insider_summary together to track both current ownership levels and recent trading direction for specific named insiders.

Compliance & Surveillance

Feed Form 4 data into internal monitoring systems to detect unusual trading patterns around earnings announcements, material events, or blackout periods. The alltransactions feed provides the filing date, transaction date, and accession number needed to reconstruct the full disclosure timeline.

Insider Sentiment Indicators

Use net_trading_activity to build quarter-by-quarter insider sentiment time series — buy/sell ratio, net share flow, and active insider count — that can be added as features to fundamental models or displayed as chart overlays on price data.

Dashboards & Research Tools

Power financial dashboards, newsletters, and alert systems highlighting notable insider trades — large open-market purchases, unusual option exercises, or sustained multi-quarter selling patterns. The insider_summary mode provides a compact per-person dataset ready for display without further processing.

Long-Horizon Ownership Studies

Combine topholders, insider_summary, and full alltransactions history to analyze how insider ownership concentration and individual stake sizes evolve through market cycles, leadership changes, and lock-up expiries.
