NEW YORK (PNN) - April 15, 2013 - The S&P 500 continues to make new lows in after-hours trading.

Right now, futures have fallen to levels around $1540 - down 2.6% on the day.

This is the biggest sell-off in stocks of 2013 so far, and comes after weaker than expected economic data out of China, weak housing data in the Fascist Police States of Amerika this morning, and of course, a massive sell-off across the commodity complex, most notably in gold.

Meanwhile, the fallout from two explosions at the finish line of the Boston Marathon this afternoon - in which two people have been reported dead and dozens injured - continues to unfold.
