We prove that the homotopy groups of the $K(n)$-local sphere are finitely generated ℤ p -modules in every integer degree, for every prime p and positive height n . Equivalently, the same conclusion holds after $K(n)$-localizing any finite p -local spectrum. This answers the degreewise finiteness question of Hovey and Hovey–Strickland.
