The higher the information ratio, the greater the chances of the manager to make money in the future. The information ratio only looks to compute the return per unit of risk undertaken for the alpha component. This is important because alpha returns are risky, as they represent a zero sum game for the market as a whole. In fact, average alpha for the market as a whole is in practice slightly less than zero because of transaction and other costs. Therefore it is easy for a manager to take on ?alpha risk? and lose money that will bite into the beta returns.
