Let G be a finite group, let A be an infinite-dimensional stably finite simple unital C*-algebra, and let α\colon G → \operatornameAut (A) be an action of G on A which has the weak tracial Rokhlin property. Let A\af be the fixed point algebra. Then the radius of comparison satisfies \operatornamerc (Aα) ≤ \operatornamerc (A) and
