Getco was reportedly valued at $1 billion two years ago and is rumored to have earned roughly half as much as that in net profit last year alone.

Until this summer, when it added some company specifics, its Web site contained little more than a reading list with recommendations like Reminiscences of a Stock Operator. Their firm, Global Electronic Trading Co., is tucked behind a nondescript door on the second floor of the Chicago Board of Trade's art deco building.
