GMO Launches Nebo, an Innovative Asset Management Platform for RIAs

Nebo (for Needs-Based Allocation) bridges the gap between financial planning and asset management, helping advisors ensure clients have the financial resources they need to achieve their goals.

BOSTON – Grantham, Mayo, Van Otterloo & Co. LLC (GMO), a global investment manager, announced today the launch of Nebo (for Needs-Based Allocation). Nebo is a new, technology-driven asset allocation and portfolio management platform for Registered Investment Advisors (RIAs) that streamlines and automates the process for delivering custom and personalized portfolios to their clients.

Recently recognized as a finalist in the “Industry Disruptor” category of the Industry Awards, Nebo’s unique approach is built on the idea that the main investment risk to clients is not short-term market volatility, but rather not having the financial resources you need, when you need them.

At the heart of the Nebo framework is a proprietary multi-period, shortfall optimizer that constructs portfolios which minimize this critical risk. In doing so, advisors are able to directly align the client’s financial plan with their portfolio resulting in portfolios that are better customized to the needs and circumstances of each client, all delivered through an open-architecture platform. Now with Nebo, advisors will be able to finally scale their financial planning and investment operations by having a comprehensive digital platform that can serve as the system of record for their portfolio construction and management activities.

“Nebo allows advisors to maintain their investment philosophy while adding intellectual rigor to the choices they make for their clients and the testing they can do to be confident that those choices best serve their clients’ needs,” said Martin Tarlie, member of GMO’s Asset Allocation team and Nebo Product Lead.

Nebo is born of nearly a decade of GMO research focused on solving for optimal portfolio construction that seeks to minimize shortfall risk, further enhanced by a three-year process of user-led development with a cohort of early adopters. These RIAs have provided valuable feedback and input, ensuring that Nebo meets the needs of fiduciary advisors.

“The launch of Nebo marks an important next chapter in deepening our relationships with RIAs through investment-led solutions. In recent years we have expanded advisors’ access to GMO strategies by making more GMO funds available on custodial platforms. The introduction of Nebo’s novel approach will help advisors improve their clients’ financial well-being and achieve their financial goals,” said Chief Executive Officer Scott Hayward.
