The algorithmic monitoring of market movements made by ultra-high-net-worth insiders and institutions.
Definition
Whale tracking is the practice of ingesting, parsing, and analyzing real-time financial filings (like Form 4 and 13F) to follow the capital flows of 'whales'—individuals or entities with enough capital to directly influence asset prices.
Why it matters for Whale Tracking
Retail investors often trade on lagging indicators like news. Whale tracking allows analysts to trade on leading indicators by mirroring the exact capital allocations of the people running the companies.
Real-World Example
"When a custom screener alerts that Elon Musk is liquidating billions of dollars in TSLA stock over a 3-day period, whale tracking allows traders to front-run the institutional sell-off that often follows such massive supply entering the market."
