Important Note: Data Limitations
These metrics are based on 13F filing data which has significant limitations:
- Quarterly Snapshots Only: 13F filings show positions at quarter-end, not actual transaction prices
- No Transaction Prices: We cannot determine actual buy/sell prices, only end-of-quarter values
- Performance Estimates: Gains/losses are calculated from first appearance to last update using quarterly values
- Missing Data: Intra-quarter trades, dividends, corporate actions, and exact timing are not captured
- Educational Only: These metrics are estimates for understanding general investment patterns, not actual realized returns
Use these metrics for informational and educational purposes only. They represent broad trends, not precise investment performance.
