It's important to understand that each mutual fund has different risks and rewards. In general, the higher the potential return, the higher the risk of loss. Although some funds are less risky than others, all funds have some level of risk - it's never possible to diversify away all risk. This is a fact for all investments.

mutual fund that sells shares of ownership and uses the proceeds to purchase short-term, high-quality securities such as Treasury bills, negotiable certificates of deposit, and commercial paper. Income earned by shareholders is received in the form of additional shares of stock in the fund (usually priced at $1 each). Although no fees are generally charged to purchase or redeem shares in a money market fund, an annual management charge is levied by the fund's advisers. This investment pays a return that varies with short-term interest rates.

It is relatively liquid and safe but varies in yields and features. Both taxable and tax-exempt varieties of money market funds are offered. Also called liquid asset fund. See also average maturity. Case Study Choosing between a taxable and tax-exempt money market fund is a function of an investor's marginal tax rate and the difference in yields between the two types of funds. A higher marginal tax rate makes it more likely an investor will earn a higher aftertax return from owning a tax-exempt fund as opposed to a taxable fund. Likewise

Each fund has a predetermined investment objective that tailors the fund's assets, regions of investments and investment strategies. At the fundamental level, there are three varieties of mutual funds:

1) Equity funds (stocks)
2) Fixed-income funds (bonds)
3) Money market funds

All mutual funds are variations of these three asset classes. For example, while equity funds that invest in fast-growing companies are known as growth funds, equity funds that invest only in companies of the same sector or region are known as specialty funds

Bond/Income Funds

Income funds are named appropriately: their purpose is to provide current income on a steady basis. When referring to mutual funds, the terms "fixed-income," "bond," and "income" are synonymous. These terms denote funds that invest primarily in government and corporate debt. While fund holdings may appreciate in value, the primary objective of these funds is to provide a steady cashflow to investors. As such, the audience for these funds consists of conservative investors and retirees.

Bond funds are likely to pay higher returns than certificates of deposit and money market investments, but bond funds aren't without risk. Because there are many different types of bonds, bond funds can vary dramatically depending on where they invest. For example, a fund specializing in high-yield junk bonds is much more risky than a fund that invests in government securities. Furthermore, nearly all bond funds are subject to interest rate risk, which means that if rates go up the value of the fund goes down.

Balanced Funds
The objective of these funds is to provide a balanced mixture of safety, income and capital appreciation. The strategy of balanced funds is to invest in a combination of fixed income and equities. A typical balanced fund might have a weighting of 60% equity and 40% fixed income. The weighting might also be restricted to a specified maximum or minimum for each asset class.

A similar type of fund is known as an asset allocation fund. Objectives are similar to those of a balanced fund, but these kinds of funds typically do not have to hold a specified percentage of any asset class. The portfolio manager is therefore given freedom to switch the ratio of asset classes as the economy moves through the business cycle.
