ATMDX Investment Objective and Strategy
PIMCO Low Duration Opportunities 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 long-term return, consistent with preservation of capital and prudent investment management.
Principal investment strategy
"The Fund seeks to achieve its investment objective by investing under normal circumstances at least 80% of its 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 Fund intends to utilize various investment strategies in a broad array of fixed income sectors to achieve its investment objective. The Fund will not be constrained by management against an index. The average portfolio duration of this Fund will normally vary from (negative) 1 year to positive 5 years based on PIMCO's market forecasts.
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 may seek to manage capital gain distributions by, among other things, attempting to use losses from sales of securities that have declined in price to offset gains that would otherwise be taxable subject to maintenance of the portfolio investment strategy. However, such strategy may be unsuccessful or only partially successful and the Fund may realize taxable gains. For example, the Fund may realize taxable gains in order to satisfy cash redemption requests or when PIMCO believes the benefits of a transaction resulting in the realization of taxable gains outweigh tax considerations.
The Fund may invest in both investment-grade securities and high yield securities (""junk bonds"") subject to a maximum of 20% of its total assets in securities rated below Baa 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 also invest without limitation in securities denominated in foreign currencies and in U.S. dollar-denominated securities of foreign issuers. The Fund may invest up to 30% of its total assets in securities and instruments that are economically tied to emerging market countries (this limitation does not apply to investment grade sovereign debt denominated in the local currency with less than 1 year remaining to maturity, which means the Fund may invest in such instruments without limitation subject to any applicable legal or regulatory limitation).
The Fund will normally limit its foreign currency exposure (from non-U.S. dollar-denominated securities or currencies) to 25% of its total assets. The Fund may also invest up to 10% of its total assets in preferred securities. The Fund may invest in derivative instruments, such as options, futures contracts or swap agreements, or in mortgage- or asset-backed securities. 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)."
