The document summarizes the theory of random walk as it relates to stock prices and markets. 2 Random Walks In this lecture, we will consider random walks on undirected graphs. If it is, then almost all long random walks that start out at a given point will revisit that point. This model assumes that in each period the variable takes a random step away from Our result allows us to determine whether or not a random walk is recurrent.
