It's a classic case of throwing the baby out with the bath water. All the non thinkers out there like scared rabbits sell at the lows and buy back at the highs always a good plan.
I went through all this in 2000 and if you have done the research and are happy with the Co then I would certainly be buying more, DIO being no exception.
Good fortune to all holders I think this stock will do well.
