Quote from bone:
Intermarket commodity spreads generate pure portable alpha.
That is exactly what they are talking about. You are generating returns completely independent from flat price directional risk. If a strategy can generate returns independent from equity market and fixed income market flat price directional risk, it is especially coveted by portfolio managers. Everybody is chasing alpha.
ML's cumulative pnl curve looks very nice - could you please elaborate on how intermarket spreads can lead to that type of curve for past 10 yrs?
