Duration for two Specific Mutual Funds?

I need to know the duration of two funds. Fidelity International Discovery (FIGRX) and Vanguard 500 Index (FVINX). Ive looked on both Fidelity's and Vanguard's website along with etrade and morningstar. Yahoo Finance just says N/A which doesnt help with my project.... Any and All help is appreciated

Duration is a figure that is used with bond funds. Duration is a complex calculation that is more representative of a bond's movement in relation to interest rate swings than the time to maturity (length in years) of a bond.

You can measure the duration of a bond mutual fund as well as an individual bond. However, the two funds you mentioned are not bond funds, so duration is a misnomer--there is no such thing as duration for a non-bond fund. That is why it says "NA" for those two funds you mentioned (NA= "Not Applicable". Not Applicable because they are NOT bond funds, they are stock funds.)

Here is a formal definition with the link provided:

The change in the value of a fixed income security that will result from a 1% change in interest rates. Duration is stated in years. For example, a 5 year duration means the bond will decrease in value by 5% if interest rates rise 1% and increase in value by 5% if interest rates fall 1%. Duration is a weighted measure of the length of time the bond will pay out. Unlike maturity, duration takes into account interest payments that occur throughout the course of holding the bond. Basically, duration is a weighted average of the maturity of all the income streams from a bond or portfolio of bonds. So, for a two-year bond with 4 coupon payments every six months of $50 and a $1000 face value, duration (in years) is 0.5(50/1200) + 1(50/1200)+ 1.5(50/1200)+ 2(50/1200) + 2(1000/1200) = 1.875 years. Notice that the duration on any bond that pays coupons will be less than the maturity because there is some amount of the payments that are going to come before the maturity date. In this example, the maturity was 2 years. Investors use duration to measure the volatility of the bond. Generally, the higher the duration (the longer an investor needs to wait for the bulk of the payments), the more its price will drop as interest rates go up. Of course, with the added risk comes greater expected returns. If an investor expects interest rates to fall during the course of the time the bond is held, a bond with a long duration would be appealing because the bond's price would increase more than comparable bonds with shorter durations.

I'm not sure I understand fully what your asking..Mutual funds have no fixed term, they are open ended and exist for one until they cash out their investment. They may be restructured, but they are still ongoing.
