Mutual Funds

A mutual fund is a professionally managed type of collective investments that pools money from many investors and puts it in stocks, bonds, short-term money market instruments, and/or other securities.[1] The mutual fund will have a fund manager, that trades the pooled money on a regular basis, and after realizing capital gains or losses are passed out in the form of dividends to the individual investors. Currently, the worldwide value of all mutual funds totals more than $26 trillion. [2]

Since 1940, there have been three basic types of investment companies in the United States: open-end funds, also known in the US as mutual funds; unit investment trusts (UITs); and closed-end funds. Similar funds also operate in Canada. However, in the rest of the world, mutual fund is used as a generic term for various types of collective investment vehicles, such as unit trusts, open-ended investment companies (OEICs), unitized insurance funds, and undertakings for collective investments in transferable securities (UCITS).

Average Annual Return

US mutual funds use SEC form N-1A to report the average annual compounded rates of return for 1-year, 5-year and 10-year periods as the "average annual total return" for each fund. The following formula is used:[6]

P(1+T)n = ERV

Where:

P = a hypothetical initial payment of $1,000.

T = average annual total return.

n = number of years.

ERV = ending redeemable value of a hypothetical $1,000 payment made at the beginning of the 1-, 5-, or 10-year periods at the end of the 1-, 5-, or 10-year periods (or fractional portion).

Turnover is a measure of the fund's securities transactions, usually calculated over a year's time, and usually expressed as a percentage of net asset value.

This value is usually calculated as the value of all transactions (buying, selling) divided by 2 divided by the fund's total holdings; i.e., the fund counts one security sold and another one bought as one "turnover". Thus turnover measures the replacement of holdings.

In Canada, under NI 81-106 (required disclosure for investment funds) turnover ratio is calculated based on the lesser of purchases or sales divided by the average size of the portfolio (including cash).

Mutual funds bear expenses similar to other companies. The fee structure of a mutual fund can be divided into two or three main components: management fee, nonmanagement expense, and 12b-1/non-12b-1 fees. All expenses are expressed as a percentage of the average daily net assets of the fund.

The management fee for the fund is usually synonymous with the contractual investment advisory fee charged for the management of a fund's investments.
