Founded in 1998, LJM Partners, Ltd. was an investment management firm based in Chicago that focused on alternative investment strategies, primarily capturing returns from the volatility risk premium by writing options. The firm managed funds for investors, aiming to deliver consistent returns. However, LJM Partners suffered catastrophic losses of over 80% in a single day during the extreme market volatility event of February 2018 (known as "Volmageddon"), which ultimately led to the firm's liquidation and closure.
