A balance chart can show a 10% drawdown while investment performance falls 32.5%. Rebuild the unit-value path, handle cash-flow timing and calculate recovery and remaining risk room.

A flat benchmark can leave a daily 2× ETF down 1.1852%. Worked examples separate compounding, fund NAV and account returns, including premiums, execution costs and break-even levels.

A falling share price can coexist with a positive return. Reconcile dividends, withholding, fees and reinvestment with a worked example and a clear break-even price.
