The 5% radar — new activist & large stakes

Cross 5% of a company's voting stock and you have to tell the SEC. A 13D is the activist version — filed when the holder might push for change. A 13G is a passive large holder. An /A is an amendment: a stake moved. This is the live feed of who just crossed the line, and where.

In your own code: free API key, then /v1/activist/latest (add ?activist_only=true for just the 13Ds) or /v1/activist/AAPL for one company. See also insider cluster buys and 13F fund holdings. 13D is filed within days of crossing 5%; 13G on a slower schedule. Not investment advice.
