I've raised this same point before. I think the dynamics could shoot this price to the moon, but what do I know? I'm with e*Trade ands it's so very nice to be with a broker who thinks of its clients as adults. The bureaucracy at some of these larger houses is worse than big government, especially when you know they ought to know, and act, better.
If you want to buy and sell GERS stock, I suggest that you use one of the two brokerage services that allow you to do that. I don't think the other firms will change their policies at this time.
