Fixed Income Strategy

Global Credit

The Nikko AM Global Credit strategy is actively managed using fundamental top-down and bottom-up credit research to create diversified portfolios. The strategy draws on fundamental credit analysis as the primary contributor of returns and complements pure credit selection and credit allocations with other drivers, including currency and interest rates.

Investment Philosophy

The investment team believes Credit is most effectively managed within a global context, allowing fundamental research to determine asset allocation and security selection, tempered by awareness of the asymmetric risks of credit exposures.

Key Differentiators

  • We do not have a home bias; nothing pre-occupies portfolio construction - our well-established fixed income teams in US, Europe, Singapore and Japan allows the Global Credit team to develop a holistic and balanced view by drawing on local expertise and on-the-ground research of these teams.

  • We employ a pragmatic approach and deploy our resources to areas where we see value.

  • We are innovative. Credit research and Risk Management are supported by proprietary quantitative models which allow us to focus on alpha generating ideas.

  • We are communicative. Regional teams communicate both formally and informally to share information and research. This additional insight allows the team to execute quickly once they have made a decision.

Our Team

The Global Credit team is comprised of four investment professionals headed by Holger Mertens and supported by Steve Williams, Ee-Yung Yip and Marco Sun. The team sits within the wider Global Fixed Income team based in London, led by Andre Severino which consists of 16 investment professionals with an average of 16 years of investment management experience.

The London team has significantly broadened over time to support the strategies’ growth and cater to institutional portfolios. One of our biggest advantages is the fluid interaction and ability to execute decisions quickly across four categories: Currency, Core Markets, Emerging Market Debt and Global Credit.

Global Credit also draws upon regional insight from Nikko AM’s credit specialists located in the US, Europe, Singapore and Japan. There are over 20 dedicated credit investment professionals across Nikko AM’s global investment network.

Our Process

The investment process draws upon a global team of research analysts which follow a consistent investment process that incorporates quantitative and qualitative inputs from experienced investment professionals. The process is disciplined and transparent, which engages the team in a collaborative process to generate ideas and construct a high quality Global Credit portfolio.

Embedded Risk Management

Ongoing risk management is integral to the entire investment process with constant dialogue between our investment and independent risk management teams in ensuring that risks are identified, evaluated, monitored and mitigated. The Global Credit investment management team divides risk into systematic and unsystematic components and both the former and latter are constantly monitored and controlled to keep risk within the strategy at an appropriate level.

Independent to the investment team, Nikko AM Europe’s risk management department oversee the strategy and closely monitors market, credit, operational and portfolio management risk and takes appropriate measures to minimise the impact of potential risk. The risk management process starts with Risk Budgeting and the Risk Management Department which conducts independent, detailed analysis of portfolio risk and characteristics, as well as performance attribution and peer group analysis. The risk process consists of risk budgeting and monitoring with clearly detailed escalation procedures at every step.

The Risk Management Department truly understands the investment management process and therefore feedback and a meaningful dialogue between the investment team and risk managers takes place as part of the firm’s continuous communication flows.
