According to the semi-strong form of the efficient market hypothesis, stock prices reflect all publicly-available information. Therefore, investors should not be able to earn excess returns by trading on public information. Nevertheless, trillions of dollars are invested with active fund managers whose mission it is to generate these excess returns. Passive investments, on the other hand, offer investors the opportunity to simply be the market" not "beat the market". Imagine you have started a career as a financial advisor, and one of your clients wishes to start saving for retirement. Your client has asked you to answer the following questions: 1) Explain the difference between active fund management and passive fund management. 2) What is the argument for investing in actively managed mutual funds? 3) What is the argument for investing in passively managed mutual funds? 4) I am planning to save $500 per month for retirement. Do you recommend that I invest in actively managed funds or passively managed funds? Please explain your recommendation
