how's the saying go - "buy on speculation, sell on confirmation" most of these U companies are 4 years + (guessing) from making any money. First they'll need to spend a truck load of money to make anything happen....same for any mining stock.
i have a simple graph that shows the life cycle of a mining stock...i'd ike to paste it in post but don't know how?
good luck to all those that hold U stocks - one things for sure, it's going to be a nervous rollercoster ride.
