GAM Investments Strengthens European Equities Platform with Appointment of leading Investment Team
Tom O’Hara, Jamie Ross and David Barker join from Janus Henderson to manage flagship GAM Star European Equity and Continental European Equity funds
GAM Investments is pleased to announce the appointment of a new European Equities team comprising Tom O’Hara, Jamie Ross and David Barker. As of 15 May 2025, the team has assumed investment management responsibilities for the GAM Star European Equity and GAM Star Continental European Equity funds.
This highly regarded team joins from Janus Henderson Investors and brings with them a style-agnostic, high-conviction investment approach that complements GAM’s longstanding heritage in European equities. The appointment marks a further milestone in GAM’s corporate transformation and ongoing commitment to investment excellence.
Tom O’Hara, Investment Director, European Equities at GAM, commented: "It’s great to be joining GAM. This is a very exciting time in the company’s turnaround, supported by a long-term focused majority owner and a strong, investment-led culture that traces its roots to Gilbert de Botton. On a personal level, my investing career started thanks to John Bennett - who spent 17 years at GAM managing European Equities and always spoke highly of the firm’s investment ethos. So it really feels like a natural fit for us to be here."
"Our approach will remain consistent with our past. We are managing a concentrated, high-conviction portfolio of around 30 stocks, using our simple and repeatable ‘All-in’ framework", added David Barker. "This combines expected earnings growth, cash return and valuation change to assess whether a company’s return potential exceeds that of the broader market."
A core, consistent and transparent investment process
While the team brings a fresh perspective, they remain committed to delivering a core, style-agnostic strategy which builds on the legacies of both GAM and their own history as successful European equity investors. Their process is grounded in fundamental research and offers clear, data-driven insights for clients.
David Barker highlighted, "We want to be open-source. That means sharing our investment insights, process and return assumptions with clients transparently and consistently across all our communications."
A turning point for Europe
The team also believes the macro backdrop is shifting decisively in Europe’s favour.
"For decades, cheap valuations alone weren’t enough to catalyse change in Europe. But that’s no longer the case. Geopolitical realignment sparked, in part, by the return of Donald Trump has done more for EU unity than any post-war president," said Jamie Ross. "We’re seeing a more assertive Europe: a looser fiscal stance in Germany, more coherent messaging from EU leaders, and growing momentum for innovation, investment, and regulatory simplification."
"Europe has a generational opportunity to redefine itself - compelled by a geopolitical realignment that demands cohesive action across industrial policy, energy security and tech sovereignty. These shifts will create a new generation of winners across the region. We believe this marks a key turning point for the European equity market."
Elmar Zumbuehl, Group CEO of GAM Investments, added "We are delighted to welcome Tom, Jamie and David to GAM. Their fresh approach, tight teamwork and use of advanced technology fully embraces the transformational changes underway in active investing. Their arrival significantly strengthens our specialist active equity offering and with investor interest returning to Europe, we see this as a powerful step forward for GAM’s specialist active equities platform and our clients."
Investors are encouraged to contact their local GAM relationship manager to learn more about the strategies or meet the team through upcoming events, webinars and roadshows.
