Always regular for (0, ∞) and (−∞, 0). CGMY processes CGMY (u) Path variation: Hitting points: Creeping: Regularity: = −C (−Y )[(M − iu)Y − M Y + (G + iu)Y − GY )] − iuµ. Unbounded variation ⇔ Y ∈ [1, 2). C = ∅ ⇔ Y = 1 or Y ∈ (0, 1) and µ = 0, otherwise C = R. Upwards creeping ⇔ Y ∈ (0, 1) and µ > 0. Downwards creeping ⇔ Y ∈ (0, 1) and µ < 0. Irregular for (0, ∞) ⇔ Y ∈ (0, 1) and µ < 0. Irregular for (−∞, 0) ⇔ Y ∈ (0, 1) and µ > 0.

Even if the moments of the process are known, it is still possible to match only a finite number of them. In any case, moment matching is equivalent to fitting the characteristic function only at zero. Kellezi and Webber (2004) [17] found it preferable to construct a lattice directly from the density function (known for the examples they give). Nevertheless, their lattice has very high order branching, is relatively slow, still runs into problems when attempting to price American options, and in any case cannot value path-dependent options.
