Compound Annual Growth Rate (CAGR)

Compound Annual Growth Rate (CAGR) is the geometric mean return of a portfolio over a multi-year period — it answers "if you had simulated this portfolio with $X, what's the equivalent annual return?"

For Disclosed Capitol, each politician's CAGR is derived from a daily backtest: starting from a baseline, the simulator buys each disclosed asset on the transaction_date in the amount-bracket midpoint, sells per their disclosed sales, and prices the resulting portfolio against historical daily closes. The CAGR is the annualized return of that simulated portfolio from the politician's first ingested trade through today.

Important caveats: - The 45-day disclosure window means a real-money copy trader can't replicate these returns — they only see the trade after the filing posts, often weeks later. - Bracket midpoints can be off by 10× on either side (e.g., $1M–$5M midpoint is $3M). - Options trades are modeled at underlying-stock equivalence — actual options returns can be 5-10× higher or lower.

Disclosed Capitol publishes CAGR (annualized_return_pct) on every politician profile and ranks members on the leaderboard.
