Filings land all through the day: 13Fs in a rush before each deadline, Form 4s every business day, 13Ds within days of someone crossing 5%. Nobody can refresh EDGAR all day. HoldingScout checks it every 10 minutes, and a watchlist tells you when something you follow moves.
Start small
Pick the few things you’d actually act on: a fund whose thinking you respect, a company you own, or an insider at that company. A free account can watch one; Pro can watch up to 100. Even then, a short list you read beats a long one you ignore.
Example Capital filed its 13F
3 new · 5 added · 2 sold out
Acme Corp’s CEO bought $1.2M
Form 4 · open-market purchase
Activist Partners filed a 13D on Globex
6.1% stake
Pick a pace
- Hourly (Pro) if you follow insider buying closely and want trades the day they’re filed.
- Daily for most people: one email, everything that moved.
- Weekly if you invest for the long run and want the big picture.
Prune it every quarter
When the new 13Fs arrive, look back at your list. Drop what you stopped caring about, and add the funds and companies that kept coming up in your reading.
