The renormalized $\phi^4_4$-trajectory by perturbation theory in the   running coupling
  We compute the renormalized trajectory of $\phi^4_4$-theory by perturbation theory in a running coupling. We introduce an iterative scheme without reference to a bare action. The expansion is proved to be finite to every order of perturbation theory.
