Guys!
You tell me if i got it right, but it seems that the benchmark performance is NOT adjusted for the multiple variation of invested capital of the related portfolio.
In other words, our portfolio performance pa is weight averaged for the time of investment, and so the shorter the time since my last Buy, the lower the weight averaged time of the total portfolio investment, the greater the total pa performance.
THIS do not happen for the benchmark you display!!! It shows a performance that is as if I invested money 1 time in T0, the time of “my first purchase” of the portfolio, and it does not adjust for new injection of capital due to new buys in the related portfolio.
IF it is, then the two performances are NOT at all comparable and so the service is - at best - misleading…
Am I wrong?
