InsiderRadar

Find insider transactions reported to the SEC on Form 4, from 2020 to today (country=US, the default), or in the registers of the Netherlands (AFM), Germany (BaFin), Belgium (FSMA), Sweden (FI) and Spain (CNMV) with country=NL, DE, BE, SE or ES, the five European registers together with country=EU, or all of them with country=all. European rows are one line of the regulator's register each, in the currency of the filing with a euro value next to it, and every row names its source (source, source_url); cite it when you use a row. For Form 4: Filter by ticker, company, insider name, role, buy or sell, a date range, a minimum value and Rule 10b5-1 plans; sort newest first or by largest value. By default the lines of one filing with the same transaction code are combined into one row (total shares, weighted average price, total value, number of lines). For 'the largest recent insider purchases' use type=buy and sort=largest_value. Each row has the insider and their role, the dates, shares, price, value in USD, whether it was a planned trade, source_url (the filing at the SEC) and company_url (our company page, when there is one). Open-market purchases and sales since mid-June 2026 also carry the latest price and the change from the price in the filing to that latest price: a measurement of the share price, not advice.

Summarize the Form 4 filings of one company (ticker or name) or one insider over a period, from 2020 to today: how many filings, lines and insiders; open-market purchases and sales (count, shares, USD value, and how much of it was under a Rule 10b5-1 plan); every transaction type; the most active insiders; and the largest filings with their source_url. Default period: the last 365 days.

Across the whole US market: the companies whose insiders bought (or sold) the most in the open market over a period, ranked by USD value. Each company has the total value, shares, number of filings and insiders, the share of the value that was under a Rule 10b5-1 plan, and its largest filing with source_url. Planned trades are left out by default (planned=exclude) and the answer says so. Common and other non-derivative shares only (Form 4 Table I). Default: the last 7 days; at most 90 days, and at most 31 for periods before 2026-06-15.

Find stock and other asset trades reported by members of the US Congress (House and Senate Periodic Transaction Reports under the STOCK Act; branch=congress, the default) or by the US President (OGE Form 278-T, as read from the scanned filings by Open Cabinet, a third party; branch=executive). Filter by a person's name, chamber, ticker, purchase or sale, and a period. Amounts are bands as filed (amount_band, with its bounds in USD), never exact amounts. Congress rows carry the days from trade to filing and whether the filing came after the legal deadline, with the fact. The filings give no price; where the share has a price series the row carries the change in the share price since the filing (and for the executive since the trade). Every row carries source_url, the filing; executive rows also credit Open Cabinet. Default period: the last 365 days.

The quarterly 13F holdings of the fund managers InsiderRadar follows (e.g. Berkshire Hathaway, Baupost): give fund for one manager's positions in a quarter, or issuer for which followed managers held a company. Each position has the shares and value in USD this quarter and the previous one, whether it is new, increased, decreased, sold out or unchanged, and its share of everything the fund reported. Default quarter: each fund's latest report. Holdings at quarter end, filed up to 45 days later; no prices paid, no short positions, no cash.

What a listed US company spent on federal lobbying, per quarter, from the Lobbying Disclosure Act reports (lda.gov): its own in-house expenses and the income outside lobbying firms reported from it, kept apart, plus its most recent reports with links. Give ticker or company. Without either, a ranking of the listed companies with the largest own lobbying expenses over the last four quarters.
