Hedge fund billionaire John Overdeck confronts a historic marital dissolution claim in New Jersey, with his ex-wife demanding a substantial equity stake in Two Sigma Investments.

John Overdeck, co-founder of quantitative hedge fund Two Sigma Investments, revealed that the firm lost a significant investor because of an ongoing dispute with fellow co-founder David Siegel.

During the start of their divorce trial, the lawyer for Laura Overdeck stated that Two Sigma Investments' billionaire co-founder John Overdeck schemed to leave his wife with as little as possible, an amount she valued at $633 million.
