• Quant employment verification: UNRESOLVED. Identity is supported (LinkedIn sjeon00 + IMO 2019 Canada bronze for Sebastian Jeon from Bergen County Academies; both consistent), but every employment lead — HRT, Jump Trading, Five Rings, Loomis Sayles — rests on INDEX/AGGREGATOR-only data (the LinkedIn enrichment index) or the caller's unverified lead list, with no independent primary-source confirmation of a role or internship. Employer classification: Hudson River Trading and Jump Trading are quantitative/high-frequency proprietary trading firms; Five Rings (LLC) is a quantitative proprietary trading firm; Loomis Sayles is an asset manager with a quantitative research group — all operate in quantitative finance, but the person's actual employment at any of them remains unconfirmed. Student/olympiad programs listed do not establish employment.Sep 17, 2026
