  Within the extremal black hole attractors arising in ungauged
$\mathcal{N}\geqslant 2$-extended Maxwell Einstein supergravity theories in
$3+1$ space-time dimensions, we provide an overview of the stratification of
the electric-magnetic charge representation space into "large" orbits and
related "moduli spaces", under the action of the (continuous limit of the)
non-compact $U$-duality Lie group. While each "large" orbit of the $U$-duality
supports a class of attractors, the corresponding "moduli space" is the proper
subspace of the scalar manifold spanned by those scalar fields on which the
Attractor Mechanism is inactive. We present the case study concerning
$\mathcal{N}=2$ supergravity theories with symmetric vector multiplets' scalar
manifold, which in all cases (with the exception of the minimally coupled
models) have the electric-magnetic charge representation of $U$-duality fitting
into a reduced Freudenthal triple system over a cubic (simple or semi-simple)
Jordan algebra.
