The Standard Deviation for ANH ranges from .025¢ to .125¢ and you can see the movement from low to high back to low like clockwork on any given chart. Right now, it's in the process of decreasing from .125 and is presently at .092. A Standard Deviation of .006 represents the average and would be a buy point, even more so if the share price hits the 50 DMA.
Think your over-reacting. ANH is sure to take a little hit when the market goes south - maybe even a little more if housing becomes a concern but like many REIT's, it will bounce back time after time.
