How has the model actually done?

⚠ Important limitations: This backtest has look-ahead bias — it assumes you knew investor holdings on the quarter-end date, but 13F filings aren't actually published until up to 135 days later. It also has survivorship bias: the tracked investors were selected because they're already famous winners — a list picked with hindsight will look better than one picked in advance. Transaction costs, taxes, and slippage are not modelled. Past results do not predict future performance. This is an educational tool, not investment advice.
