A healthy dose of "ignore user" cleans the board up, especially since there are only about four or five people who don't realize this is the Alcoa financials board.
Earnings projections are that Q1 earnings will be even higher than on January 10th (Q4 '10), so I'm not sure immediately selling is a good idea... but that depends on your strategy.
My advice is this - bigger companies tend to respond slower to news, so even if you wanted out after earnings, I'd wait a little to see what the price action does.
Best,
