Is this the lowest for Alcoa?

This is the world's third largest aluminium company and a S&P 500 company with:

market cap = 8.7B
PE = 68 (high due to low demand and falling aluminium prices)
P/B = 0.7
EV/EBITDA = 7.1
profit margin = 0.6%
ROE = 0.7%
current ratio = 1.1
dividend = 1.5%

The industry has been seeing shrinking demand and falling aluminium prices. As a result, earning has also been shrinking. As the stock price falls accordingly, it is supported at a base price. That is why, the PE is high at 68. I will be targeting to buy below US$8.
