PAIUX Investment Objective and Strategy
PIMCO Short Asset Investment Fund describes its objective and strategy as follows, from its latest prospectus filed with the SEC by PIMCO Funds.
Investment objective
The Fund seeks maximum current income, consistent with daily liquidity.
Principal investment strategy
"The Fund seeks to achieve its investment objective by investing under normal circumstances at least 65% of its total assets in a diversified portfolio of Fixed Income Instruments of varying maturities, which may be represented by forwards or derivatives such as options, futures contracts or swap agreements. ""Fixed Income Instruments"" include bonds, debt securities and other similar instruments issued by various U.S. and non-U.S. public- or private-sector entities. The average portfolio duration of this Fund will vary based on Pacific Investment Management Company LLC's (""PIMCO"") market forecasts and will normally not exceed one and one-half years. Duration is a measure used to determine the sensitivity of a security's price to changes in interest rates. The longer a security's duration, the more sensitive it will be to changes in interest rates.
The Fund invests primarily in investment grade debt securities rated Baa or higher by Moody's Investors Service, Inc. (""Moody's""), or equivalently rated by Standard & Poor's Ratings Services (""S&P"") or Fitch, Inc. (""Fitch""), or, if unrated, determined by PIMCO to be of comparable quality. The Fund may not invest in securities denominated in foreign currencies, but may invest without limit in U.S. dollar-denominated securities of foreign issuers. In addition, the Fund may invest up to 10% of its total assets in U.S. dollar-denominated securities and instruments that are economically tied to emerging market countries. The Fund may invest up to 60% of its total assets in corporate issuers. The Fund may invest, without limitation, in derivative instruments, such as options, futures contracts or swap agreements, subject to applicable law and any other restrictions described in the Fund's prospectus or Statement of Additional Information.
The Fund may invest up to 20% of its total assets in asset-backed securities and up to 10% of its total assets in privately issued mortgage-backed securities. The Fund may invest up to 10% of its total assets in interest rate swaps and up to 5% of its total assets in credit default swaps. The Fund may purchase or sell securities on a when-issued, delayed delivery or forward commitment basis and may engage in short sales. The Fund may, without limitation, seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as buy backs or dollar rolls)."
