Convertible Bonds
Mirabaud Sustainable Convertibles Global Strategy
A high-conviction, highly active strategy investing in global convertible bonds targeting 50 best ideas, with the top-20 positions representing around 60% of the portfolio.
Mirabaud Sustainable Convertibles Global is style and benchmark agnostic. This unconstrained, agile approach allows us to meet our participation rate targets.
We only invest in 'pure' convertibles (no synthetic securities) and only use hedging to manage currency risk.
Extensive fundamental analysis of balance sheet strength and potential equity upside is combined with full ESG integration. Shadow ratings using Moody’s methodology is used for unrated credits.
This approach helps us to find hidden value and minimise default risk.

We believe in a pure-play focus on convertibles where issuers have a sustainable focus to maximise convexity. We do not hold synthetic securities or options, which means the portfolio is completely transparent
