What is InsiderStreet.ai?

InsiderStreet.ai is a free financial intelligence platform tracking smart-money signals — insider trades, congressional stock disclosures, hedge fund positions, ETF flows, dark pool activity, and short interest — across 88,000+ securities.

How do I track which hedge funds own a stock?

On any stock page on InsiderStreet, the Hedge Fund Holders tab shows every fund holding that stock — names, position size, quarterly changes, and fund flows. Data is sourced from SEC institutional ownership disclosures.

How do I see which Congress members trade a stock?

Each stock page has a Smart Money tab that shows congressional disclosures under the STOCK Act — senators and representatives, transaction type, date, and dollar range — typically disclosed within 45 days of the trade.
