What the record says

Description, identity and filings, each with its source.

Every block cites its source. The colour of a finding marks its category — which document, who filed it — not how much it matters.

SEC topics

Topics detected in its SEC reports, with the original excerpt.

Each topic is assigned by a classifier over the full filing; the excerpts show where it was detected and are not always enough to verify it. Open the filing to read it in full.

Reverse splits in 5 years

1 reverse split in 5 years (1:10 on Mar 21, 2023) · 1:10 cumulative

The other times: of 818 securities that did their first reverse split in 5 years, a year later the median was worth 0.53× the price on the day of the split; 382 lost more than half and 209 rose (809 with a price a year later).

Our own series, not the whole market: based on the splits we have on record (provider and SEC); an unrecorded one does not count. Historical distribution, not a prediction.

Ownership and control

Schedule 13G: short-form filing

The short form, for holders who meet specific requirements: institutional investors, passive investors without a control purpose, or exempt investors. Asset managers and index funds usually file it.

Its sector and its market

NioCorp Developments Ltd. among Materials companies

The profile shows what is on record. Context and Radar place the company among those of its sector and region.

With an account you also get

  • The four engines — growth, trend, risk and context — each with its word and its score.
  • The risk band and the sector phase.
  • The company's fundamentals and accounts.
  • Watchlist: your list of companies, with the «since you follow it» figure.

The research continues

The profile tells the story. The market sets the scene.

From NioCorp Developments Ltd., the path continues in the other areas. Each one is shown with its own example, named in its step.

  1. Place it in its market

    Seven layers of its region's market — rates, credit, stress, liquidity, regime, breadth and sectors — with historical precedents. Public example: Apple and ASML.

  • No account

    This profile for every company we cover: closing prices with the record's facts on the curve, the SEC file in plain language, insider trades included, and links to its sector and exchange.

  • Pro

    What matters today, with its reason, is free with an account. Pro adds, in the profile, each company's notices and their explanation and the analysis of its insiders; in Radar, all the lenses, which notice each candidate carries, filters by notice type and «no dilution», and the cycle cohort filter; and in Watchlist, more companies and notice changes with their reason.

  • Pro+

    Adds the Lab: test a hypothesis on comparable cohorts before reusing it; and bring your lenses to Radar.

Are the prices real time?

No. It is one close per session, from the provider and with the date shown on the profile; it does not update during the trading day.

Which SEC documents appear here?

Those filed with the SEC by the company, its insiders and its major shareholders, within our coverage: periodic reports (10-K, 10-Q, 20-F), material events (8-K), proposed sale notices (Form 144), insider transactions (Form 4) and stakes above 5% (13D/13G). Each links to the original on EDGAR.

Why does a European company show no SEC records?

It depends on the company: some European issuers file a 20-F or 6-K with the SEC and others don't. The profile shows whatever is on record; when there is nothing, it says so rather than guessing why. Europe does not yet have a common filing archive like EDGAR in the United States. The EU will open its own, ESAP, in July 2027 (managers' transactions arrive in January 2028), and we plan to add it once it is available.

Before forming a view on a company,
read what is on record.

One close per session. The record in plain language. Its sector and its market one link away. Your judgment when deciding.

Access by invitation while the beta lasts. Not advice: the profile shows what is on record; it does not recommend.
