Alcoa kicks off each earnings season, and it's been their "above expectations" results that have kick-started this rally each of the last 3 quarters just as the markets seemed ready for a correction. This time, the markets seemed poised for another improbable run up the scales and what happens? Alcoa comes in with a disappointing quarter. After all the hype about the economy turning the corner, one would think a supplier of aluminum would cash in pretty handsomely on a recovering economy. After all, if it doesn't start with manufacturing more stuff, "stuff" nowadays sure as hell needs aluminum, then where is it going to start? So will this trigger the much-needed correction?
