Many of the unconventional properties of high-Tc superconductors in the underdoped regime of the phase diagram can be understood from the assumption that the charge carriers are susceptible towards charge and spin ordering. The substantiation of this hypthesis requires a technique which is able to deal with the excitations of an inhomogeneous, strongly correlated system. In this talk I will present results from the time-dependent Gutzwiller approximation for the Hubbard model which allows for the computation of random-phase approximation (RPA) –like fluctuations on top of the Gutzwiller approximation (GA). Within this formalism static and dynamical properties of stripe textures in cuprates are investigated. Besides a brief presentation of the technique and results for the optical conductivity the main emphasis of the talk will be on the discussion of magnetic excitations of stripes in connection with recent neutron scattering experiments. It is shown that the GA+RPA approach can account for the main features present in these spectra, namely a low-energy incommensurate acoustic branch which merges into a  ``resonance peak'' at the antiferromagnetic (AF) wave vector and high-energy AF-like optical branches.
