C000099381 Investment Objective and Strategy
Pioneer Corporate High Yield Fund describes its objective and strategy as follows, from its latest prospectus filed with the SEC by Pioneer Series Trust X.
Investment objective
A high level of current income.
Principal investment strategy
"The fund selects investments from a broad spectrum of debt securities. The fund is managed using a benchmark unconstrained approach, which means that it is not managed relative to an index. Accordingly, the fund does not seek to generate returns consistent with broader financial market movements, instead seeking to generate positive total returns over the course of different market environments. Total return is a combination of current income and capital appreciation. The fund also may use derivatives for a variety of hedging and non-hedging purposes. Normally, the fund invests at least 80% of its net assets (plus the amount of borrowings, if any, for investment purposes) in debt securities. For purposes of satisfying the 80% requirement, the fund may invest in derivative instruments that provide exposure to such debt securities or have similar economic characteristics.
The fund has the flexibility to invest in a broad range of issuers and segments of the debt securities markets. The adviser allocates the fund's debt securities among different instruments and segments of the debt markets, based on its outlook for economic, interest rate and political trends. Debt securities may include instruments and obligations of U.S. and non-U.S. corporate and other non-governmental entities, those of U.S. and non-U.S. governmental entities, mortgage-related or mortgage-backed securities (including ""sub-prime"" mortgages), asset-backed securities, floating rate loans, convertible securities, preferred securities, Treasury Inflation Protected Securities (""TIPS"") and other inflation-linked debt securities, subordinated debt securities, event-linked bonds and other insurance-linked securities, municipal bonds and funds that invest primarily in debt securities.
The fund may invest without limit in debt securities of any credit quality, including those rated below investment grade (known as ""junk bonds"") or, if unrated, of equivalent credit quality as determined by the fund's investment adviser. The fund's investments in debt securities rated below investment grade may include securities that are in default. The fund may invest in securities of issuers located in emerging markets. The fund invests in securities with a broad range of maturities and maintains an average portfolio maturity that varies based upon the judgment of the adviser. The fund's investments may have fixed or variable principal payments and all types of interest rate payment and reset terms, including fixed rate, adjustable rate, floating rate, zero coupon, contingent, deferred, payment in kind and auction rate features.
The fund's investments may include instruments that allow for balloon payments or negative amortization payments. The fund may invest in equity securities as a consequence of holding debt of the same issuer or when the adviser believes the securities offer the potential for capital gains or other portfolio management purposes, although equity securities may not pay dividends or contribute to achieving the fund's primary investment objective of a high level of current income. The adviser considers both broad economic and issuer specific factors in selecting a portfolio designed to achieve the fund's investment objectives. In assessing the appropriate maturity, rating, sector and country weightings of the fund's portfolio, the adviser considers a variety of factors that are expected to influence economic activity and interest rates.
These factors include fundamental economic indicators, such as the rates of economic growth and inflation, Federal Reserve and other global monetary policies and the relative value of the U.S. dollar compared to other currencies. Once the adviser determines the preferable portfolio characteristics, the adviser selects individual securities based upon the terms of the securities (such as yields compared to U.S. Treasuries or comparable issuers), liquidity and rating, country, sector and issuer diversification. The adviser also employs fundamental quantitative and qualitative research to assess an issuer's credit quality, taking into account financial condition and profitability, future capital needs, potential for change in rating, industry outlook, the competitive environment and management capabilities.
In selecting among market segments and instruments, the adviser considers the relative value of particular investments. The adviser may sell a portfolio security when it believes the security no longer will contribute to meeting the fund's investment objectives. The adviser makes that determination based on the same criteria it uses to select portfolio securities. In making these portfolio decisions, the adviser relies on the knowledge, experience and judgment of its staff and the staff of its affiliates who have access to a wide variety of research. In addition to seeking to manage portfolio risk through conventional means, including through in-depth credit analysis and diversification, the adviser employs derivative strategies designed to limit the effects of severe market events. Derivatives in which the fund may invest for this purpose include credit default swaps, futures and options, and swaps.
The fund also may use derivatives for a variety of other purposes, including: in an attempt to hedge against adverse changes in the market price of securities, interest rates or currency exchange rates; as a substitute for purchasing or selling securities; to attempt to increase the fund's return as a non-hedging strategy that may be considered speculative; to manage portfolio characteristics; and as a cash flow management technique. The fund may establish, through derivatives, net short positions for individual sectors, markets, currencies or securities, or as a means of adjusting the fund's portfolio duration or other portfolio characteristics. The fund may invest without limit in derivative instruments. The fund may choose not to make use of derivatives for a variety of reasons, and any use may be limited by applicable law and regulations.
The fund also may hold cash or other short-term investments."
