Efstathios Metsovitis

Efstathios 'Stathis' Metsovitis (Greek) represented Greece at the 2001 International Mathematical Olympiad (bronze medal) and holds an M.A. in Operations Research and Financial Engineering from Princeton University (2008). UK and US regulatory records place him at Caxton Associates, a discretionary global-macro hedge fund, as an LLP Member (UK, from January 2025) and a Manager of the US adviser entity. Contact-data aggregators additionally list an earlier rates/derivatives trading career at Credit Suisse (2008-2011), Morgan Stanley (2011-2012) and Brevan Howard (2012-2014); those past roles are index-derived and not independently confirmed.

Notes8

• Quant employment verification: CONFIRMED. Present role established by primary-source evidence: Efstathios Metsovitis is recorded as an LLP Member of Caxton Associates LLP (UK company OC345117) in a UK Companies House filing, appointed 1 January 2025, and appears as Manager (control person) of Caxton Associates (USA) LLC, a New York SEC-registered investment adviser, in a record derived from SEC Form ADV. Employer classification: Caxton Associates (founded 1983) is a discretionary global-macro hedge fund - a genuine hedge fund, but not an explicitly quantitative/systematic-strategy firm, and the 'quant' label cannot be read from the name. Identity support: an IMO 2001 Greece contestant named Efstathios Metsovitis and a Princeton Hellenic Studies page under the same name; the Companies House and SEC-derived records carry only the same full name (no birth date corroboration). Caveat - the title 'Portfolio Manager, Associate Partner' and the prior roles (Credit Suisse 2008-2011, Morgan Stanley 2011-2012, Brevan Howard 2012-2014) are derived from contact-data aggregators/the index and are NOT independently confirmed; those past-role claims remain unresolved.Jan 1, 2025

• Two independent government/regulatory-derived records tie the full name to Caxton - a UK Companies House officer filing (LLP member, Jan 2025) and an SEC Form ADV-derived manager record - which corroborates the Caxon role beyond the LinkedIn index, though both rest on name-match alone.2025
• Caxton Associates (USA) LLC is an SEC-registered investment adviser operating as a global-macro/commodity-pool hedge-fund manager (~$4.6B AUM, CPO/CTA), confirming Caxton is a genuine quantitative-adjacent macro hedge fund rather than a name-only match.2026
• Caxton Associates is a discretionary global-macro hedge fund (founded 1983), so the 'quantitative' classification of his current employer rests on its systematic/prop-style macro trading rather than an explicitly named quant strategy.2026
