Can an artificial intelligence learn to beat the stock market?

On the far side of an office park in a suburb of Seattle, a supercomputer is teaching itself to beat the stock market. But inside this austere enclosure, an incredible alchemy is taking place. Four hundred computers blink and hum as market data is digested at a rate of one quadrillion calculations per second, firing order requests to electronic traders in Chicago, 2,000 miles away. Outside the containment, a bank of 10 glowing monitors displays the results as money rolls back in. Even now, as the world economy slumps into a recession, Jeff Glickman and his boutique investment firm, J4 Capital, are quietly taking gains. "Suffice it to say we're making a profit in this market," he says.
