Optiver Holding Portfolio holdings
Optiver Holding B.V., founded in 1986 by Johann Kaemingk, Ruud Vlek, and Chris Oomen in Amsterdam, Netherlands, is a leading global proprietary trading firm and market maker specializing in options, derivatives, equities, ETFs, bonds, and foreign exchange. Starting as an options market maker on the European Options Exchange (now Euronext), Optiver has grown into a tech-driven powerhouse with over 2,000 employees across offices in Chicago, Sydney, London, Singapore, and beyond, trading on more than 50 exchanges worldwide. Known for its advanced algorithms and low-latency systems, the firm provides liquidity and competitive pricing, emphasizing market efficiency and stability, though it faced a $14 million fine in 2012 for illegal "banging the close" tactics in U.S. oil futures. Privately owned and led by CEO Rob Defares, Optiver blends a collaborative culture with cutting-edge technology, making it a significant player in the global financial ecosystem.
