The lawsuit between Overstock and the banks concerned a phenomenon called naked short-selling, a kind of high-finance counterfeiting that, especially prior to the introduction of new regulations in 2008, short-sellers could use to artificially depress the value of the stocks they’ve bet against. The subject of naked short-selling is a) highly technical, and b) very controversial on Wall Street, with many pundits in the financial press for years treating the phenomenon as the stuff of myths and conspiracy theories.
