Pioneer Securitized Income Fund May Offer Investors


We seek to invest in out-of-benchmark assets whose unique characteristics can translate into low fundamental correlations2 to traditional stock and bond portfolios.


Securitized assets can provide attractive yield potential despite being collateralized by specific assets.


We actively manage sector and security weights and seek to capitalize on attractive opportunities across market environments.

1Diversification does not assure a profit or protect against loss. The portfolio is concentrated in securitized assets with at least 25% in mortgage backed securities.

2Correlation - The degree to which assets or asset class prices have moved in relation to one another. Correlation ranges from -1 (always moving in opposite directions) through 0 (absolutely independent) to 1 (always moving together). Past performance is no guarantee of future results.

Lending Against Unique Assets


US residential mortgages is the largest and oldest securitized sector, but through thirty years of evolution, securitizations now offer exposure to a diversity of asset types, including auto loans, office towers, industrial warehouses, hotel portfolios, cellphone towers, apartment buildings, consumer receivables, billboards, aircraft leases, shipping containers, drug royalties, and consumer and corporate receivables.  By selecting these exposure thoughtfully, the Fund seeks to invest in assets that are underrepresented in traditional stock and bond portfolios, thereby providing both attractive income and diversification opportunities.

Attractive Index Correlations to Stocks and Bonds

What Are Securitized Assets?

Securitized assets is a broad category for any financial instrument whose cash flows are derived from and secured by specific underlying assets. In a securitization transaction, assets are sold into a trust, which then issues securities backed by those assets. The assets included in securitizations are diverse, but the objective for investors is always the same: to lower the cost of capital by reducing and transferring risk.

In the private (non-agency) market, this objective is primarily pursued in three ways:

  • First and foremost, investors in securitized assets can benefit from the bankruptcy-remote nature of the securitization trust, which helps insulate their investment from the unrelated activities of the transaction’s sponsor.
  • Second, liquidity risk and the effects of a single loan default are reduced by placing hundreds of heterogeneous assets into a trust whose securities can be analyzed and transacted more efficiently, once pooled.
  • Finally, while the timing and amount of cash flows for the assets in the trust is uncertain, the securitization’s pre-defined payment rules shift these risks to the investors more willing and able to bear them.

A Word About Risk: Pioneer Securitized Income Fund

The market prices of securities may go up or down, sometimes rapidly or unpredictably, due to general market conditions, such as real or perceived adverse economic, political, or regulatory conditions, recessions, inflation, changes in interest or currency rates, lack of liquidity in the bond markets, the spread of infectious illness or other public health issues or adverse investor sentiment. The Fund invests primarily in securitized asset instruments, including mortgage-backed securities, asset-backed securities and other securities. A substantial portion of the Fund’s assets ordinarily will consist of high yield debt securities that involve substantial risk of loss. Investments in the Fund are subject to possible loss due to the financial failure of issuers of underlying securities and their inability to meet their debt obligations. Investments in high yield or lower-rated securities are subject to greater-than-average price volatility, illiquidity and possibility of default. The market price of securities may fluctuate when interest rates change. When interest rates rise, the prices of fixed-income securities in the Fund will generally fall. Conversely, when interest rates fall, the prices of fixed-income securities in the Fund will generally rise. The value of mortgage-related and asset backed securities will be influenced by factors affecting the real estate market and the assets underlying those securities. These securities are also subject to prepayment and extension risks and risk of default. The Fund may employ leverage, which increases the volatility of investment returns and subjects the Fund to magnified losses if an underlying investment declines in value. Certain securities and derivatives held by the Fund may be impossible or difficult to purchase, sell or unwind. Such securities may also be difficult to value. The use of interest rate futures and options and other derivatives can increase fund losses and reduce opportunities for gain. The Fund may invest in credit default swaps, inverse floating rate obligations, and other derivative instruments. Derivatives may have a leveraging effect on the Fund. The Fund is non-diversified, which means that it can invest a large percentage of its assets in the securities of any one or more issuers. Being non-diversified may magnify the Fund’s losses from adverse events affecting a particular issuer. Please see a prospectus for a complete discussion of the Fund’s risks.
