Investment Teams

GMO’s investment teams are all grounded in a long-term, valuation-based investment philosophy.

Each team has focused, deep expertise investing across multi-asset class, equity, fixed income, or alternative markets, and each employs its own active investment process. Some GMO teams rely on innovative quantitative tools, others use rigorous fundamental research, while many blend the two approaches.

Clients benefit from working with the leading investors of today and those who are just starting to make their marks. On average, our investment team leaders have over 20 years’ industry experience, and many have spent a large portion of their careers at GMO. This leadership group has experience investing through multiple market cycles – perspective that helps our investment teams maintain a focus on the long term. The over 100 investment professionals who work on our teams share a common set of values centered on our investment philosophy and a focus on client outcomes.

Investment teams actively collaborate and share research, using our collective experience to fine-tune our processes and produce new ideas. We regularly publish research based on this work to address a range of client issues.

Asset Allocation

Asset Allocation is a core competency of GMO, and multi-asset class portfolios represent a large portion of GMO’s assets under management. The Asset Allocation team believes that expected returns for asset classes change as valuations change, and these views are reflected in our 7-Year Asset Class Forecasts. The team’s process takes advantage of the changing opportunity set by actively rotating portfolio allocations and taking risk in line with the rewards on offer. By being valuation-sensitive investors, we successfully identified the Japanese Equity bubble (the 1980s), the Dot-Com bubble (the late 1990s), and the Global Risk bubble (the 2007-2008 timeframe), avoiding the permanent impairment of capital from the bursting of these bubbles.

GMO’s Asset Allocation team has managed asset allocation portfolios since 1988 and has been a pioneer in unconstrained, absolute return-oriented investing since first recommending this approach at our 1999 Fall Conference. With team members located in Boston, San Francisco, and London, the team can access both traditional (equity, fixed income, credit, cash) and alternative asset classes via strategies actively managed by other GMO investment teams. In this way, Asset Allocation draws on the investment expertise of the entire firm.

Developed Rates & FX

The Developed Rates & FX team members have backgrounds in finance, economics, physics, math, statistics, and computer science – experience that helps them in developing and implementing quantitative investment strategies focused on global fixed income and currency markets. The team manages both leveraged absolute return and benchmark-plus strategies, all of which benefit from alpha streams derived from proprietary models. 

Emerging Country Debt

GMO founded our emerging debt effort in 1994, making us one of the earliest dedicated investment managers in the asset class. The Emerging Country Debt team counts among its members sovereign, corporate, and local market specialists with significant experience in the asset class. The team has applied a bottom-up security selection focus since inception, an approach that sets GMO apart from other managers who stress the importance of top-down investing in emerging debt markets. 

Event-Driven

The Event-Driven team’s portfolio and risk management philosophy is governed by the belief that in an asymmetric field where losses are often disproportionate to gains, a competitive advantage can be gained by using a probabilistic framework at both the security selection and portfolio allocation levels.

Focused Equity

GMO’s Focused Equity team manages benchmark-agnostic, fundamentally driven equity portfolios: the Quality, Resources, and Climate Change Strategies. The team takes a long horizon view to investing, focusing on businesses with enduring relevance and secular growth drivers. Launched in 2004, the Quality Strategy is designed to be a core equity holding with a favorable risk return tradeoff, while the Resources and Climate Change Strategies, launched in 2011 and 2017, respectively, target specific opportunities with compelling secular tailwinds. The team’s approach is to reinforce fundamental analysis with rigorous systematic work. The experienced team is based in Boston and London and also manages long/short versions of the Quality and Resources Strategies.

Short Duration

GMO’s Short Duration Strategies team consists of portfolio manager Tracey Keenan, Head of Short Duration Strategies, and three research and implementation professionals. Given our emphasis on exploiting pricing inefficiencies in G10 sovereign debt and cash markets, we believe that the optimal portfolio management structure comprises a small, cohesive team of experienced investors with clearly defined roles working in a collaborative fashion. The team is supported by additional research, trading, and operations professionals at the firm.

Structured Products

GMO’s Structured Products team members have over 14 years’ experience on average in structured product and asset-backed security investing. The team leverages this extensive experience to employ both top-down and bottom-up analysis to identify securities that provide the best value relative to what is currently available in the market. Importantly, the team is fully empowered to buy what is truly the best value, rather than just what is in the benchmark.

Systematic Equity

The Systematic Equity team is a carefully assembled world-class quantitative research effort built on a wide array of quantitative disciplines, including backgrounds in physics, mathematics, statistics, finance, economics, accounting, engineering, operations research, and business. The team brings together long-standing GMO quantitative equity expertise into one global group of investment professionals collaborating across GMO’s Boston, San Francisco, London, and Singapore offices and applies its alpha insights to a range of U.S., international, emerging markets, and global equity strategies across the firm. The team as a whole is supported by GMO’s research team of over 100 investment professionals worldwide, which has been responsible for many innovations that keep GMO on the leading edge of investment research and development.

Systematic Global Macro

The Systematic Global Macro team was established at GMO in 1999. The team members’ tenure and experience together has enabled our investment philosophy and process to remain consistent, while our commitment to investment research facilitates the application of desired enhancements. Based in our Sydney office, the team conducts research on an ongoing basis to ensure the quantitative models used are as strong as possible. 

Usonian Japan Equity

GMO’s Usonian Japan Equity team utilizes a disciplined, bottom-up, value approach to capitalize on unique inefficiencies in the Japanese equity market. Leveraging significant experience investing in Japan, the team maintains a long-term perspective and engages with company management to help enhance corporate governance and create long-term shareholder value. The team has managed the Japan Value Strategy since 2011 and joined GMO in 2020, with team members located in GMO’s Berkeley office and a representative office in Tokyo.
