AtD (which contains everything) including 'bucket shops", precursors of credit-default swaps: the current econ crisis

[Mark Kohut]

 But it wasn't magic. It amounted to the return of the age-old scam called "bucket shops." Also sometimes known as "boiler rooms," bucket shops emerged after the Civil War. Usually, they were storefronts where people came to bet on stocks without owning them. Unlike their customers, the shops actually owned blocks of stock. If customers were betting that a stock would go up, the shops would sell it and the price would plunge; if bettors were bearish, the shops would buy. In this way, they cleaned out their customers. Frenetic bucket-shop activity caused the Panic of 1907. By 1909, New York had banned bucket shops, and every other state soon followed.
