Pretty similar to what we have all said. New legisilation shouldn't affect CAB, but who knows, maybe it will, and that slight risk and uncertainty is what has caused the fall in share price. The market hates uncertainty, but if you are certain it wont be affected then perhaps it may be a good time to think about buying more?
Won't be buying more personally because it already takes up a larger percentage of my portfolio than the percentage I'm comfortable with. This ruling isn't going to cause me to do any panic selling either. Will be just enjoying the dividend yield from this company for the time being.
