Alcoa (AA) expects a global aluminum industry deficit of 600,000 metric tons in 2012. Yeh sure, they have been saying this for years and guess what, inventories are at an all time high and still rising... In fact, even if they were right this time, the assumed deficit will take 10 years to deplete current inventory levels. Conclusion, even in the most optimistic scenario it will take 10 years for this stock to move higher. What a joke! How can this dog still be in the Dow?
