Core-Satellite Approach vs. Alpha & Beta Separation Approach

[cgottuso8190]

Can someone explain the difference between these two approaches? I must be missing something because they seem awfully similar to me…
Am I on the right track if I’m saying something like:

• In the Core-Satellite approach, the primary focus is the passive/semi-active core and the satellites are interchangeable or ‘adjustable’ pieces used to earn alpha; and
• In the Alpha & Beta separation approach, the alpha portfolio is the focus and beta exposure can be found in various ways and is the ‘adjustable’ piece?

Thanks in advance.

These are definitely very similar approaches but I think the distinction is that in Core Satellite the core doesn’t necessarily have to be just beta and the satellite doesn’t have to be just alpha.
So a US investor could have a semi active US equity portfolio as their core and a EM full blown active mandate as the satellite, most of the alpha would come from the satellite but there would still be systemtatic risk.
Whereas, alpha and beta the split is more precise in terms of systematic and unsystematic risk, so you’d buy a US equity index for the beta and maybe use a long/short equity neutral strategy for alpha
