Event-Driven Stocks

Changelog and roadmap

What we have shipped, and what comes next. We list only what actually exists or is genuinely being built, and we do not promise dates we cannot keep.

What is coming

Building now

Actively in progress.
  • Spin-off types, labelled

    Going beyond plain spin-off to mark the variant from the filing's own words: Reverse Morris Trust, tax-free versus taxable, and the rest. Only where the filing says so, never guessed.

  • Official SEC size band on company pages

    Showing each company's SEC filer category (large accelerated, accelerated, smaller reporting) next to our size tier, as the regulator-defined cross-check.

Planned next

Decided, not yet started.
  • Key dates for every event type

    Merger vote and closing, tender-offer expiry, IPO listing day. Stated from the filing only.

  • Deeper history for the other events

    Pushing mergers, tender offers, and going-private deals back toward 1994, the way spin-offs already reach.

Exploring

Worth doing if we can do it without a paid data licence.
  • Price performance, computed ourselves

    Showing how spin-offs and their parents performed, only if we can source the prices from public-domain data. We will never put a paid feed behind a free page.

  • A factor and regression tool

    Letting you test our SEC-derived signals against outcomes across the whole dataset, like a small research paper you run yourself.

  • A news cross-check

    Around big events, comparing the filing against the headlines, with the SEC filing as the source of truth.

Recent updates

June 2, 2026Tuesday
  • Each spin-off now shows how big it was at separation (small-cap, mid-cap, and so on), taken from the company's own public float as reported to the SEC. You can sort the calendars by size to surface the small-cap spin-offs the research tends to favour. The raw float and its year are shown alongside, so the figure is always checkable. No paid price data is involved.

  • We added the pre-2001 spin-offs straight from EDGAR's full filing index, so the catalog now goes back to the start of electronic filing. We also filled in missing parent companies on older records and removed a few filings that were not actually spin-offs.

  • Seven plain-English guides so far: how a spin-off happens, how to read a Form 10, merger arbitrage, Schedule 13D activism, the forensic accounting scores, distressed and bankruptcy investing, and more. Plus worked case studies from our own catalog, like AbbVie out of Abbott and Kyndryl out of IBM.

  • We scanned every merger we track and flagged 113 that were terminated, so the calendar no longer implies a dead deal closed.

  • Report an error

    Every event and company page now has a one-click way to flag a correction. We check each report against the filing before changing anything.

June 1, 2026Monday
  • Put any two companies side by side, with a fast search box to find them.

  • See where events happen by state, with a slider to move through time.

  • Faster, steadier pages

    Trimmed what each page loads and added background monitoring, so the site is quicker and catches its own errors.
