Daily Returns
Daily percentage return beside BMRN.
Daily Out/Under-Performance

Cumulative Out/Under-Performance
Relative wealth over 1mo: compounded portfolio wealth divided by compounded BMRN 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.
