Advanced Portfolio Management-When you buy a mutual fund, you pay a management fee as part of your expense ratio, which is used to hire a professional portfolio manager who buys and sells stocks, bonds, etc
Dividend Reinvestment-Cash is not paid out to the investor when dividends are paid on the stocks in the fund. Instead, cash is automatically used by the fund's administrators to buy more fund units on behalf of the investors and transfer them to individual investors' accounts.
Risk Reduction-Reduced portfolio risk is achieved through the use of diversification, as most mutual funds will invest in anywhere from 50 to 200 different securities—depending on the focus.
Convenience and Fair Pricing-Mutual funds are easy to buy and easy to understand and they are traded only once per day at the closing net asset value.
