Signal8 is for US stock traders and investors who want to check the filings, ownership activity and potential share dilution behind a ticker. Company pages bring together quotes, charts, financial details, news and SEC filings, with information on insider transactions, institutional holdings and publicly disclosed congressional trades. AI-generated filing summaries can help readers identify key details, while links to original filings let them check the source themselves. For traders monitoring smaller stocks, Signal8 includes a premarket scanner and Radar alerts, plus dilution data covering items such as warrants, convertible securities, shelf registrations and at-the-market offerings. Watchlists and alerts help users follow selected companies. Signal8 is a research and market-information tool; its summaries are not investment recommendations.
