Generating a vector from successive multiplications of another vector from an initial value

Hi all. What is the fastest way to do the following: I have an initial value V and a vector vec of (financial) indexes. I want to generate a new vector nvec as V, V*vec[0], V*vec[0]*vec[1], V*vec[0]*vec[1]*vec[2], ... A numpy vectorized solution would be better. Thanks --
