Who it is for
Why is it so hard to keep up with insider filings?
Here is the problem.
Form 4 filings are one example of what you may want to watch.

Here is the problem. When company insiders buy or sell shares, the filings that disclose it are public. In theory anyone can read them. In practice, most people hold several stocks, have a day job, and never open the SEC's website until something has already moved the price.
Form 4 filings are one example of what you may want to watch. They are the filings that show insider transactions. Checking each company by hand, every day, is tedious, and a filing that matters can sit unnoticed next to a dozen routine ones.
SEC Stock Signals is built for people who hold or follow a handful of companies and want to hear when something new is filed, without watching a feed. You pick a watchlist. When a breaking SEC filing hits one of those companies, you get an alert with AI analysis that explains what changed and what it could mean for your portfolio.
It is a reporting tool. It tells you what was filed and why it may matter. It does not tell you to buy or sell, and it never acts on your behalf.
Use cases
4 ways people use Insider buying and selling alerts: what Form 4 filings show.
- Filing on your holdingFiling on your holding
1. A new filing lands on a stock you own
Situation: you own shares in a few companies and are at work when one of them files with the SEC. You would not have known until you happened to look.
What the alert does: because the company is on your watchlist, you get an alert as the filing hits. It says what changed and what it could mean for your holding, and it links to the original document.
What you do next: read the short summary, open the original if it looks relevant, and decide for yourself whether it changes anything.
- Executive changeExecutive change
2. A leadership change shows up in an 8-K
Situation: a company you follow changes its chief financial officer. The news is in an 8-K, which is easy to miss in the stream of company updates.
What the alert does: it tells you a new 8-K was filed, that the CFO is changing, and what that could mean for your holding.
What you do next: read the linked filing and check whether the change fits your view of the company. The alert gives you the facts, and the judgment stays with you.
- Daily watchlist checkDaily watchlist check
3. A quick daily check instead of a daily hunt
Situation: you do not want push alerts all day, but you do want to know if anything happened. You ask your AI assistant, in the app's own style of question: anything new on my watchlist today?
What the alert does: the answer comes back with what is new, a summary of what changed and why it may matter, and a link to the original filing. If nothing was filed, there is nothing to chase.
What you do next: open only the filings that look relevant and skip the rest.
- Event-study verdictsEvent-study verdicts
4. Checking whether an event moved the stock before
Situation: a filing arrives and you wonder how seriously to take it. The free plan includes event-study verdicts, integrity checks, and event families, which help you see what kind of event you are looking at.
What the alert does: it gives you that context alongside the summary, so a filing is not just a headline. Ticker and watchlist lookups are part of Premium, which is free during the beta.
What you do next: use the context to decide how much time the filing deserves.
