13D Alerts
Public 13D activist stakes on the names you follow, the day the filing is up.
13D alerts catch activist stakes as soon as the filing is public.
A Schedule 13D is what a holder files after crossing 5% with an intent to influence. It is the public "we are here" document. The letter, the board fight, the "strategic alternatives" quote, those often follow. The filing is the first page you can actually cite.
Keyword alerts on "activist" will also send you every op-ed that used the word. That is how inboxes die.
Why 13Ds move books
A new 13D on a small name can re-rate the stock before the campaign even starts. Amendments matter too. A bump in the stake, a new plan, a switch from 13G to 13D. You want the filer, the issuer, the percent, and whether the purpose section is boilerplate or a fight.
AyeWatch watches public EDGAR pages and the news that quotes a 13D. It summarizes that a named holder filed on a named company. It is not a full activist database with 20 years of campaign outcomes. It is not MNPI. The 13D is public when it is accepted.
Same-day public
Filers have ten days after crossing 5%. You cannot invent a faster legal clock. What you can do is stop learning about the filing from a weekly "activism roundup." Watch the form, the issuer list, and a few known activists by name.
Topic example: "Alert me when a new 13D or 13D/A hits these issuers, or when these funds file a 13D. Ignore generic activism explainers." Add the EDGAR search URL you already use.

What it is not
It is not a promise the campaign wins. It is not a rumor feed. If the purpose section is empty calories, the alert should still be short enough that you can ignore it in five seconds.
