How this basket is built
A cluster is three or more different insiders of one company with an open-market purchase reported within the same 30 days (SEC Form 4). A company joins the session after the report becomes public, because nobody could act on it before, and the position is opened at that session's close. It stays for 60 days after the newest qualifying report, and leaves when that report is older. At most 60 companies are held: the most recently reported.
The basket is rebalanced to equal weights every session, with no trading costs and no dividends. It describes what a rule on public reports would have done. It is not what anyone owns, past results say nothing about the future, and none of this is investment advice.
