What is the random walk theory?

What will be an ideal response?


The random walk theory is the theory that prices of stocks move independently in securities markets and, hence, that there are no predictable trends that can be used to make riskless profits. The theory assumes that information about companies and stocks quickly are processed by the market and reflected in changed prices. This process happens so fast that no one can generate riskless profits.
