Robert worked for European fund managers such as Threadneedle and Credit Suisse Asset Management as a U.S. and global fund manager for nine years.

In late 2009 he joined Merrill Lynch’s research sales and then Oppenheimer. While on the sell side, Robert’s clients consistently asked him to do bespoke research projects, leading to the partnership with Vipin and Abacus Research.

Robert has consistently been a generalist, but has expertise in technology, healthcare, industrials, financials and mid cap. Historically he had been style agnostic running mostly concentrated portfolios, with a US benchmark or thematic bias.

Robert holds a Masters in mechanical engineering from Bristol University.

Vipin worked as a senior analyst and portfolio manager at Allianz Global Investors from 2009 to 2016. After a successful turnaround of Global Ecotrends Fund, he went on to launch Allianz Global Selection Fund, an unconstrained 20-stock portfolio with a bias towards high quality and contrarian styles. Both the funds substantially outperformed their benchmarks.

Prior to joining AGI he served as a Global Energy fund manager at Credit Suisse. Vipin worked as an energy and industrials analyst at various companies such as DSP Merrill Lynch Ltd, Deutsche Morgan Grenfell, Dresdner Kleinwort and HSBC based out of London, NY, Singapore and Mumbai .

Vipin holds an MBA from IIM Ahmedabad and a B.Tech in Chemical Engineering from IIT Delhi.

We believe it's all about how deep your research goes 

At Abacus we pride ourselves on our commitment to leaving no stone unturned. We ask the difficult questions, with two analysts collaborating on a single company, exploring every avenue, and communicating our findings in detail to our Clients. 

Between us we have the knowledge and experience to research and write reports that really count. We set ourselves apart with the quality of those reports, and the depth of the research behind them. That is what drives us.


With Abacus you won't find hundreds of scantily researched potential opportunities thrown at you to see which one sticks. But you will find detail, companies extensively scrutinised, and opportunities presented with clarity. Once you have read an Abacus report you will not look back.
