WhaleWisdom

WhaleWisdom is a specialized platform for tracking institutional investor 13F filings, hedge fund holdings, and insider transactions. The platform processes thousands of quarterly filings and presents them with analytics that go beyond raw data — including conviction scores, position changes, and a proprietary WhaleScore that ranks stocks by institutional ownership quality.

The WhaleIndex tracks a basket of stocks with the highest concentration of top-performing hedge fund ownership. The platform also tracks 13D/13G activist filings, giving investors early warning when activist funds build positions in companies they plan to pressure for change.

WhaleWisdom's data depth makes it popular with professional investors and analysts who want to understand what smart money is doing. The platform covers over 5,000 institutional filers and allows filtering by fund type, size, strategy, and recent activity.
