What It Is

13D Watch is an activist shareholder and insider trading intelligence service built by Long Street Consulting, LLC. Positioned between institutional-grade platforms and retail screeners, it primarily targets emerging managers with AUM under $1 billion. It does not provide investment advice; instead, it structures and cross-references public filings and market-related data so funds or research teams can make their own judgments.

Core Features and Data

At its core, the product ingests every SEC Schedule 13D/13G filing and parses the filer, issuer, ticker, event date, number of shares held, ownership percentage, and original SEC link. Each activist filing is overlaid with Form 4 insider transactions, with a particular focus on flagging Code-P open-market purchases within 90 days before or after a 13D filing. It also adds holdings consensus from ten well-known managers and FINRA short interest data. Pro further provides a “three-factor signal”: cases where an activist 13D, insider Code-P purchase, and congressional purchase all occur in the same stock within a configurable window, accessible via API or real-time alerts.

Pricing and Trial

Pricing is clear but not cheap: Demo is free; Standard costs $1,500/month or $15,000/year and includes full historical 13D/G data, insider cross-references, institutional consensus, short-interest data, 48-hour delayed alerts, a rate-limited read-only API, and 1 seat. Pro costs $3,000/month or $30,000/year, adding real-time alerts, webhooks, custom watchlists, a macro context layer, higher API limits, and 3 seats. Pilot provides 30 days of full Standard access with no credit card required, but you need to schedule a 30-minute call first.

Pros and Cons

The main strengths are transparent data sourcing—directly from primary sources such as SEC EDGAR, FINRA, congressional trading disclosures, FRED, and CFTC—and an emphasis on making every number traceable back to the original record. Its cross-signal design is more useful for event-driven research than simply looking up 13D filings or running holdings screens. The drawbacks are that the price is clearly not suited to individual investors; Standard alerts are delayed by 48 hours; the publicly available information does not disclose the start date of historical coverage, SLA, or specific API limits; and the current purchasing process is still relatively consultation-driven.

Who It’s For and Access From China

13D Watch is better suited to single-PM funds, RIAs, family offices, multi-PM funds, and research organizations—especially teams that need to integrate U.S. public filing data into internal investment research pipelines. Access from China is not disclosed in the available text. On payments, the site only mentions that Stripe self-serve checkout will be available later; the pilot currently does not require a credit card. Comparable alternatives include 13D Monitor and WhaleWisdom Pro.
