No-hair theorems for naked singularities?

In general relativity, a naked singularity is a gravitational singularity without an .... Penrose –Hawking singularity theorems · Primordial ...

Answer 2

For black holes, we have no-hair theorems that say, under certain assumptions about the matter fields, that they are uniquely characterized by just a few parameters. Are there any such theorem for naked singularities? For example, the Kerr–Newman metric has a naked singularity for certain values of the charge and spin, so we would have a two-parameter family of naked singularities. But it seems that this family isn't all-inclusive, since we can have things like Penrose-Hawking "thunderbolts"...?[Penrose 1999]
