Alcoa has become extended and been a great trade that I took part in from 2013, but I don't thin there is much upside left. Given the Fibonacci extensions and inability to break the 50dma after-hours given 3Q earnings I think we are simply seeing a re-test of a broken trend line and setting up for a move lower. I would not be surprised to see a "sell the news" scenario play out in the coming days.
