Daily Returns

Daily percentage return beside ROK.

Cumulative Out/Under-Performance

Relative wealth over 1y: compounded portfolio wealth divided by compounded ROK 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.
