I have been buying for seven year so you may be asking the wrong person, however it looks the strongest it ever has and if I had $10 to $20K to trow around I would buy and hold till the end of September after that you are on your own with DD to see how far they will go. Till then I think it will be a no brainer, homerun, double bagger maybe triple, what ever termenology you want to use.
Good Luck
P.S. No one that I have turned on to ERTH is in the plus colum as of yet and some have several hundred thousand shares.
