Cumulative growth
Daily Returns
Daily percentage return beside ALK.
Daily Out/Under-Performance

Daily Alpha
Portfolio daily return minus β × ALK 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 6mo: compounded portfolio wealth divided by compounded ALK 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.
