Optiver Holding Portfolio holdings
Optiver Holding is a Dutch market maker that trades for its own account, and its name comes from the Dutch word for "option trader". Johann Kaemingk, Ruud Vlek and Chris Oomen founded it in 1986 to make markets in options on the European Options Exchange, which became Euronext. Its traders continuously quote buy and sell prices across global markets, using the firm's own money and advanced technology, so that others can trade easily. It is privately owned and trades listed derivatives, stocks, ETFs, bonds and foreign exchange, and has spread to Asia-Pacific since opening in Australia in 1996. In 2019 it joined American rival Virtu in funding Equiduct, a trading venue that competes with national stock exchanges.
