The following information replaces similar information found under the heading "Description of Principal Security Types" in the "Fund Basics" section on page 9.

Forward-settling securities involve a commitment to purchase or sell specific securities when issued, or at a predetermined price or yield. When a fund does not already own or have the right to obtain securities equivalent in kind and amount, a commitment to sell securities is equivalent to a short sale. Payment and delivery take place after the customary settlement period.

The following information replaces similar information found under the heading "Principal Investment Risks" in the "Fund Basics" section beginning on page 10.

Leverage Risk. Derivatives, forward-settling securities, and short sale transactions involve leverage because they can provide investment exposure in an amount exceeding the initial investment. Leverage can magnify investment risks and cause losses to be realized more quickly. A small change in the underlying asset, instrument, or index can lead to a significant loss. Assets segregated to cover these transactions may decline in value and are not available to meet redemptions. Forward-settling securities and short sale transactions also involve the risk that a security will not be issued, delivered, available for purchase, or paid for when anticipated. An increase in the market price of securities sold short will result in a loss. Government legislation or regulation could affect the use of these transactions and could limit the fund's ability to pursue its investment strategies.

The following information replaces the similar information found in the "Fund Management" section on page 24.

The fund's annual management fee rate is 0.05% of its average net assets.

STATEMENT OF ADDITIONAL INFORMATION

October 30, 2010

Effective immediately, the general research services agreement with Fidelity Research & Analysis Company has been terminated on behalf of the fund.

The following information replaces the similar information found in the "Investment Policies and Limitations" section on page 4.

The fund does not currently intend to sell securities short, unless it owns or has the right to obtain securities equivalent in kind and amount to the securities sold short, except for sales of to be announced (TBA) securities, and provided that transactions in futures contracts, options, and swaps are not deemed to constitute selling securities short.

The following information supplements the information found in the "Investment Policies and Limitations" section on page 12.

A fund may also engage in purchase or sales of "to be announced" or "TBA" securities, which usually are transactions in which a fund buys or sell mortgage-backed securities on a forward commitment basis. A TBA transaction typically does not designate the actual security to be delivered and only includes an approximate principal amount. TBA trades can be used by a fund for investment purposes in order to gain exposure to certain securities, or for hedging purposes to adjust the risk exposure of a fund portfolio without having to restructure a portfolio. Purchases and sales of TBA securities involve risks similar to those discussed above for other when-issued and forward purchase and sale transactions. In addition, when a fund sells TBA securities, it incurs risks similar to those incurred in short sales. For example, when a fund sells TBA securities without already owning or having the right to obtain the deliverable securities, it incurs a risk of loss because it could have to purchase the securities at a price that is higher than the price at which it sold them. Also, a fund may be unable to purchase the deliverable securities if the corresponding market is illiquid. In such transactions, the fund will set aside liquid assets in an amount sufficient to offset its exposure as long as the fund's obligations are outstanding.

Effective February 1, 2011, the following information replaces the similar information found under the "Management Contract" section on page 25.

Management Fee. For the services of FMR under the management contract, the fund paid FMR a monthly management fee at the annual rate of 0.22% of the fund's average net assets throughout the month for periods prior to February 1, 2011. Effective February 1, 2011, for the services of FMR under the management contract, the fund pays FMR a monthly management fee at the annual rate of 0.05% of the fund's average monthly net assets throughout the month.
