Are CFDs Considered “Securities” for US Tax Purposes?

CFDs are generally not considered "securities" for US tax purposes but are treated as capital assets. This distinction is important because the wash sale rule applies only to "stock or securities." However, the IRS may argue that a CFD is a contract with respect to a security, making the wash sale rule applicable.
