Abstract
We study two models of random multiplicative functions: Rademacher random multiplicative functions supported on the squarefree integers , and Rademacher random completely multiplicative functions . We prove that the partial sums and change sign infinitely often as , almost surely. The case is left as an open question and we stress the possibility of only a finite number of sign changes, with positive probability.
