Poulin will be responsible for analysing global high yield investment opportunities aligned to Newton’s thematic investment process.
His direct report is Parmeshwar Chadha, who is the lead manager for over £1bn of AUM in high yield bond positions.
In his five years at Standard & Poor’s Poulin was part of the corporate ratings group and structured credit analytical team.
Prior to this he worked at BNP Paribas as an analyst in its credit portfolio management department.
Paul Brain, Newton’s global fixed income investment leader, said: "Increased client interest in Newton’s absolute return products has resulted in a higher demand to incorporate high yield bond assets into the portfolios. Parmeshwar and his colleague, Scott Freedman, have been instrumental in aiming to deliver strong investment returns for clients.
"As the growth in this area of our business continued, it became clear that we needed to appoint a new team member who had an in-depth knowledge of high yield fixed income investing."
The global fixed income team at Newton is now 10-strong and manages over £6.1bn of AUM.
