Our approach to investment-grade credit
Investment grade bonds offer the potential benefits of attractive yields and enhanced diversification. Our unique approach to portfolio construction helps capture these benefits and deliver consistent returns relative to the benchmark. We seek to achieve this with lower correlation to credit markets and peers, while still providing downside protection.
Robust portfolio construction
Our proprietary risk allocation process uses custom sectors and targets volatility to match the benchmark. This allows a more flexible risk allocation approach when incorporating our best idiosyncratic ideas, while also generating returns from multiple sources.
Bottom-up value seeking
We complement our portfolio construction process with high-conviction stock selection. We manage concentrated portfolios of fewer issuers than competitors, drawing on our expertise in fundamental credit analysis. This can lead to excess returns uncorrelated to market beta and low correlation with peers.
Connected across capabilities
Our team and processes draw on the expertise of our full fixed income team, allowing us to allocate to the most attractive opportunities, regardless of currency, from issuers around the world. Environmental, Social and Governance (ESG)* considerations and engagement play a critical role in our stock selection, holding equal importance alongside other risk factors.
The investment manager always applies the Firm’s Baseline Exclusions Policy and any specific constraints within a prospectus or IMA, but any other ESG factors or risk considerations are adopted at the manager’s discretion.
Bond Voyage: A journey into fixed income
Each month, our freewheeling fixed-income newsletter gathers insights from our high-yield, investment-grade, emerging-market and global sovereign bond teams.

Key risks
Investment and currency risk
The value of an investment and any income from it can go down as well as up and can fluctuate in response to changes in currency and exchange rates. Investors may not get back the original amount invested.
Credit and interest rate risk
Bond values are affected by changes in interest rates and the bond issuer's creditworthiness. Bonds that offer the potential for a higher income typically have a greater risk of default.
Illiquid securities risk
Some investments could be hard to value or to sell at a desired time, or at a price considered to be fair (especially in large quantities). As a result their prices can be volatile.
Sustainability risk
The level of sustainability risk may fluctuate depending on which investment opportunities the Investment Manager identifies. This means that the fund is exposed to Sustainability Risk which may impact the value of investments over the long term.
