Type of Funds

The largest category is that of equity or stock funds. As the name implies, this sort of fund invests principally in stocks. Within this group are various subcategories. Some equity funds are named for the size of the companies they invest in: small-, mid-, or large-cap. Others are named by their investment approach: aggressive growth, income-oriented, value, and others. Equity funds are also categorized by whether they invest in domestic (U.S.) stocks or foreign equities. There are so many

different types of equity funds because there are many different types of equities. A great way to understand the universe of equity funds is to use a style box, an example of which is below.

Another big group is the fixed income category. A fixed-income mutual fund focuses on investments that pay a set rate of return, such as government bonds, corporate bonds, or other debt

instruments. The idea is that the fund portfolio generates interest income, which it then passes on to the shareholders.

Sometimes referred to as bond funds, these funds are often actively managed and seek to buy relatively undervalued bonds in order to sell them at a profit. These mutual 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 riskier 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.

Another group, which has become extremely popular in the last few years, falls under the moniker "index funds." Their investment strategy is based on the belief that it is very hard, and often

expensive, to try to beat the market consistently. So, the index fund manager buys stocks that correspond with a major market index such as the S&P 500 or the Dow Jones Industrial Average (DJIA). This strategy requires less research from analysts and advisors, so there are fewer expenses to eat up returns before they are passed on to shareholders. These funds are often designed with cost-sensitive investors in mind.

Balanced funds invest in a hybrid of asset classes, whether stocks, bonds, money market instruments, or alternative investments. The objective is to reduce the risk of exposure across asset classes.This kind of fund is also known as an asset allocation fund. There are two variations of such funds designed to cater to the investors objectives.

Some funds are defined with a specific allocation strategy that is fixed, so the investor can have a predictable exposure to various asset classes. Other funds follow a strategy for dynamic allocation percentages to meet various investor objectives. This may include responding to market conditions, business cycle changes, or the changing phases of the investor's own life.

The money market consists of safe (risk-free), short-term debt instruments, mostly

government Treasury bills. This is a safe place to park your money. You won't get substantial returns, but you won't have to worry about losing your principal. A typical return is a little more than the amount you would earn in a regular checking or savings account and a little less than the average certificate of deposit (CD). While money market funds invest in ultra-safe assets, during the 2008 financial crisis, some money market funds did experience losses after the share price of these funds, typically pegged at $1, fell below that level and broke the buck.

Income funds are named for their purpose: to provide current income on a steady basis. These funds invest primarily in government and high-quality corporate debt, holding these bonds until maturity in order to provide interest streams. While fund holdings may appreciate in value, the primary objective of these funds is to provide steady cash flow to investors. As such, the audience for these funds consists of conservative investors and retirees. Because they produce regular income, tax-conscious investors may want to avoid these funds.

An international fund (or foreign fund) invests only in assets located outside your home country. Global funds, meanwhile, can invest anywhere around the world, including within your home country. It's tough to classify these funds as either riskier or safer than domestic investments, but they have tended to be more volatile and have unique country and political risks. On the flip side, they can, as part of a well-balanced portfolio, actually reduce risk by increasing diversification, since the returns in foreign countries may be uncorrelated with returns at home. Although the

world's economies are becoming more interrelated, it is still likely that another economy somewhere is outperforming the economy of your home country.

This classification of mutual funds is more of an all-encompassing category that consists of funds that have proved to be popular but don't necessarily belong to the more rigid categories we've

described so far. These types of mutual funds forgo broad diversification to concentrate on a certain segment of the economy or a targeted strategy. Sector funds are targeted strategy funds

aimed at specific sectors of the economy, such as financial, technology, health, and so on. Sector funds can, therefore, be extremely volatile since the stocks in a given sector tend to be highly correlated with each other. There is a greater possibility for large gains, but a sector may also collapse (for example, the financial sector in 2008 and 2009).

A twist on the mutual fund is the exchange traded fund (ETF). These ever more popular investment vehicles pool investments and employ strategies consistent with mutual funds, but they are structured as investment trusts that are traded on stock exchanges and have the added benefits of the features of stocks. For example, ETFs can be bought and sold at any point throughout the

trading day. ETFs can also be sold short or purchased on margin. ETFs also typically carry lower fees than the equivalent mutual fund. Many ETFs also benefit from active options markets, where investors can hedge or leverage their positions. ETFs also enjoy tax advantages from mutual funds. The popularity of ETFs speaks to their versatility and convenience.
