Downer really got burnt bad. I can understand his negative feelings. It sounds like he may have had too many of his eggs in one basket. I don't like to be negative with someone who has been too hurt financially. I've had some miscues (to put it very mildly) in mining but I wasn't completely destroyed by them. I recovered.
The current management wasn't around except at tail end and they were just cleaning up the mess that was left. I feel really good about this management. I wasn't around for other management so don't have much personal history on them.
I think it would be better if he tracked down the old management and see which companies their habitating at. He could stalk them all till they die. Buy 1 share of stock and attend their stackholder meetings. Ask angry questions. Write them nasty letters. He can get his revenge.
