Former CERN Pension Fund chief executive Théodore Economou is set to lead Lombard Odier Investment Managers’ (LOIM) multi-asset and fiduciary management business.

Economou announced he was stepping down from the CERN fund in July 2014 but said he expected to stay chief executive until his tenure finished in August this year and assist with the search for his successor.

However, he will now join the Swiss private bank’s asset management arm from February, serving as CIO of its multi-asset business, which manages around $5.2bn (€4.5bn) in assets.

While still at CERN, he was announced as an adviser to the Lombard Odier Pension Fund to help develop its risk-based investment strategy, which it initiated in 2009.

Based in Geneva, Economou will develop the Lombard Odier Pension Fund investment model to run for external pension clients and sovereign wealth funds.

He spent five years at the head of CERN’s fund, developing a risk-based approach for its investments, which became known as the CERN Model.

Prior to this, he was assistant treasurer of ITT Corporation and managed pension fund assets and liabilities based in New York.

Economou will report to Jan Straatman, LOIM’s CIO.

On Economou’s appointment, Straatman said: “Théodore’s depth of experience running pension funds and his outstanding knowledge of their investment needs in building portfolios will be extremely valuable to our clients.”
