OPBCX Investment Objective and Strategy
Invesco Core Bond Fund describes its objective and strategy as follows, from its latest prospectus filed with the SEC by Aim Investment Funds (invesco Investment Funds).
Investment objective
The Funds investment objective is to seek total return.
Principal investment strategy
Under normal market conditions, the Fund invests at least 80% of its net assets, plus borrowings for investment purposes, in investment-grade debt securities (generally referred to as bonds), and in derivatives and other instruments that have economic characteristics similar to such securities. Debt securities can include: ? Domestic and foreign corporate debt obligations; ? Domestic and foreign government debt obligations, including U.S. Government securities; ? Mortgage-related securities; ? Asset-backed securities; and ? Other debt obligations. The portfolio managers overall strategy is to seek to build a diversified portfolio of corporate and government bonds. The Funds investments in U.S. Government securities may include securities issued or guaranteed by the U.S. Government or its agencies or federally-chartered entities referred to as instrumentalities.
There is no required allocation of the Funds assets among the above classes of securities, but the Fund focuses mainly on U.S. Government securities and investment-grade corporate debt securities. Some of the U.S Government securities that are issued directly by the U.S. Treasury that the Fund may invest in are: Treasury bills (having maturities of one year or less when issued), Treasury notes (having maturities of one to ten years when issued), Treasury bonds (having maturities of more than ten years when issued) and Treasury Inflation-Protection Securities (TIPS). When market conditions change, the portfolio managers might change the Funds relative asset allocation. The Fund invests in securities that are rated investment-grade. Investment-grade securities are considered to be those instruments that are rated BBB- or higher by S&P Global Ratings (S&P), or Baa3 or higher by Moodys Ratings (Moodys), or the equivalent by another nationally recognized statistical rating organization (NRSRO).
If two or more nationally recognized statistical rating organizations have assigned different ratings to a security, the investment adviser uses the highest rating assigned. The Fund may also invest in unrated securities, in which case the Funds investment adviser, Invesco Advisers, Inc. (Invesco or the Adviser), may internally assign ratings to certain of those securities, after assessing their credit quality, in investment-grade categories similar to those of NRSROs. There can be no assurance, nor is it intended, that the Advisers credit analysis is consistent or comparable with the credit analysis process used by a NRSRO. The Fund may also invest in illiquid or thinly traded securities. The Fund may also invest in securities that are subject to resale restrictions and securities exempt from registration under the Securities Act of 1933, as amended (Securities Act), such as those contained in Rule 144A promulgated under the Securities Act.
The Fund has no limitations on the range of maturities of the debt securities in which it can invest and may hold securities with short-, medium- or long-term maturities. The maturity of a security differs from its effective duration, which attempts to measure the expected volatility of a securitys price to interest rate changes. For example, if a bond has an effective duration of three years, a 1% increase in general interest rates would be expected to cause the bonds value to decrease about 3%. To try to decrease volatility, the Fund seeks to maintain a weighted average effective portfolio duration within +/- two years of the duration of the Bloomberg U.S. Aggregate Bond Index, measured on a dollar-weighted basis using the effective duration of the securities included in the portfolio and the amount invested in each of those securities.
However, the duration of the portfolio might not meet that target at all times including due to market events or interest rate changes that cause debt securities to be repaid more rapidly or more slowly than expected. The Fund may invest a portion of its assets in foreign debt securities, including securities issued by foreign governments or companies in both developed and emerging markets. The Fund may not invest more than 20% of its net assets in foreign debt securities. The Fund may also use derivatives to seek increased returns or to seek to increase or decrease its exposure to certain markets or to seek to manage investment risks. The Fund is not required to use derivatives in seeking its investment objective or for hedging and might not do so. Futures, swaps, forward contracts, options, and structured notes are examples of some of the types of derivatives the Fund can use.
The Fund may purchase and sell securities on a when-issued and delayed delivery basis, which means that the Fund buys or sells a security with payment and delivery taking place in the future. The Fund may also engage in to be announced (TBA) transactions, which are transactions in which a fund buys or sells mortgage-backed securities on a forward commitment basis. TBA transactions may be conducted as dollar rolls. The Fund may engage in short sales of TBA mortgages, including short sales on TBA mortgages the Fund does not own. The Fund may hold a portion of its assets in cash and cash equivalent instruments, including affiliated money market funds, as margin or collateral for the Fund's obligations under the TBA transactions, or for cash management purposes. In selecting investments for the Fund, the portfolio managers analyze the overall investment opportunities and risks in different sectors of the debt securities markets by focusing on business cycle analysis and relative values between the corporate and government sectors.
The Fund mainly seeks income earnings on the Funds investments plus capital appreciation that may arise from decreases in interest rates, from improving credit fundamentals for a particular sector or security or from other investment techniques. The Funds credit research process considers factors that may include, but are not limited to, an issuers operations and capital structure. The Fund may sell securities that the portfolio managers believe no longer meet the above criteria. In attempting to meet its investment objective or to manage subscription and redemption requests, the Fund may engage in active and frequent trading of portfolio securities.
