Nothing company specific This drop in share price has all to do with dividend stocks going out of favor for the first time in years combined with selling stocks that have given a nice capital gain over the years.
The company is stronger today then it was back in 2008. A quick drop is quite possible from here with the rest of the dividend payers like the banks and pipelines. Any gut wrenching drop in AW is a buying opportunity that doesn't come along very often.
