Goldman Sachs . . . Darth Vader and Luke Skywalker?

Goldman Sachs emerges as both a villain and an unlikely hero in Michael Lewis's new book Flash Boys . . . what Goldman did to computer coder Serge Aleynikov was mean-spirited, unnecessary, and illogical, but in the end, the company helps bolster the use of the new IEX market that Brad Katsuyama and a select group of Wall Street rebels create, in order to protect regular traders and investors from the predatory practices of high-frequency traders and "dark pools" . . . the story is just as exciting as The Blind Side, although a bit more technical, and you'll be astounded at how the modern stock market really works: think Mahwah instead of Manhattan.
