Actors support having a hierarchy of SceneComponents. Each Actor also has a RootComponent property that designates which Component acts as the root for the Actor. Actors themselves do not have transforms, and thus do not have locations, rotations, or scales. Instead, they rely on the transforms of their Components; more specifically, their root Component. If this Component is a SceneComponent, it provides the transformation information for the Actor. Otherwise, the Actor will have no transform. Other attached Components have a transform relative to the Component they are attached to.
