What an insider alert can tell you
Here “insider trading” means transactions publicly reported by company insiders. An app can monitor those disclosures; it cannot tell you what an executive will do before a filing exists. The transaction date and the filing date may differ, so an alert should be read as a prompt to inspect the disclosure, not as advance market information.
Stock Alarm describes portfolio insider alerts tied to Form 4 activity. This can fit someone who already uses its wider alert system. Confirm the current membership and phone delivery details before assuming a particular alert is included.
InsiderSignal presents itself in its App Store listing as a specialist for insider buy and sell alerts. A focused tool can be appealing if insider filings are your main task; check its coverage and transaction filters in the current version.
Stocklet is useful when you want insider disclosures for chosen stocks alongside earnings, price, and news alerts. Its insider feature page describes the available transaction categories. Stocklet's alert is informational and depends on supported public data and processing.
Compare the filing details, not only the push channel
A purchase, a sale, and an option exercise are not interchangeable. Check the reporting person, transaction code, price, shares, ownership after the transaction, footnotes, and whether several transactions are related. The insider-buying guide explains how to review those details.
Choose a specialist if you primarily research insider filings. Choose a broader alert app if the filing is one of several company events you follow. In either case, open the original disclosure before forming a view.
Stocklet provides informational notifications, not investment advice. Alert timing depends on when source information becomes publicly available and is processed.
