While it is certainly possible that some perceive that stock has outrun dividend, this appears to be class profit taking. Just compare the chart to other oil trusts, such as SJT, which had a comprabable pull back today. If you had a good chunk of your savings in this position, you may do the same. I think this is the explanation for the sporadic moves in the trusts. See NLY for comparison, which has dropped precipitiously since reducing its dividend.
