Cumulative growth

Daily Returns

Daily percentage return beside COF.

Daily Out/Under-Performance

Portfolio return minus COF return. Positive bars indicate outperformance.

Daily Alpha

Portfolio daily return minus β × COF return. Early observations use the first valid beta; later observations use the trailing beta estimated for each date.

Cumulative Out/Under-Performance

Relative wealth over 1y: compounded portfolio wealth divided by compounded COF wealth, less one. Both series rebase at the selected span's start.

Cumulative Alpha

Compounded beta-adjusted residual returns apply the first valid beta to early observations, then the trailing beta ending on each date.
