Question 1

Which markets and filings are covered?

Accepted Answer

Korea: DART insider ownership reports (D001, D002) and D005 pre-disclosure plans across KOSPI and KOSDAQ, since February 2024. Japan: every EDINET large-shareholding (5%) report since 2021, translated and purpose-tagged. United States: SEC Form 4 open-market purchases by officers and directors since July 2023. Korea and Japan are live, and new filings reach the dashboard within a week of publication. The United States tab is built and not open to every account yet: ask for early access and we will write to you when it opens.

Question 2

What is a D005 pre-disclosure plan?

Accepted Answer

Since July 2024, Korean executives and shareholders with 10% or more must file a plan at least 30 days before a large trade in their company's shares (1% of the shares or ₩5 billion over six months), stating what they intend to buy or sell. The dashboard lists every plan with its status and matches it against the trades that followed, so you can see plans that were completed, still in progress, or withdrawn.

Question 3

What does the star rating mean?

Accepted Answer

It summarises the filer's own record. Korean insiders are ranked by the historical average return on their buys. Japanese investors get a composite of 70% five-year and 30% three-month filing returns; the top 8% earn five stars. US officers and directors are rated on the 180-day return of their open-market buys against the S&P 500, shrunk by n/(n+5) so one lucky trade cannot top the table.

Question 4

Does a high rating predict the next buy?

Accepted Answer

No. In every market it is a track record, not a forecast. For the US, an out-of-sample check found that top-quintile records did not beat on the next buy. For Japan, the activist return edge did not hold on 2025 filings, while the link between activist stakes and later takeovers did. Use the rating to know who is filing, not to size a trade.

Question 5

Can I get the data instead of the dashboard?

Accepted Answer

Yes. The Korean and Japanese tables are available through the StockDrifts Data API and as an MCP server, and as Parquet for institutions. US Form 4 data is not on the API yet.

Question 6

What does it cost?

Accepted Answer

API and MCP access is part of the StockDrifts Ultra plan: $69 a month, or $49 a month billed annually. You create the key yourself under Settings, API keys, as soon as you upgrade, and you can cancel anytime. Institutional licences with flat files and team access start with a four-week trial on full history.
