John Stewart has recently joined ACG in the capacity of an investment advisor. As a way to attract additional clients, John has asked your help in preparing some educational material for a seminar taking place later this month. As part of a discussion about current investment practices and theories, John has asked you to write a brief presentation about systematic and unsystematic (also known as nonsystematic) risk. John also wants you to briefly explain a stock's beta coefficient and how it ties into systematic versus unsystematic risk.
