GHDC was trading OK until one of the MMs dropped the ask from .039 to .033 near the end of the day. GHDC went public well after SFMI. It's still well under radar, even more than SFMI, and more thinly traded (though it's catching up), so it's still more volatile. Here's a link to one of my previous posts- I did some back of the napkin calcs to show that SFMI should be at most 5-6X GHDC, and an even smaller multiple until production ramps up Goldcorp Holdings . So GHDC is a bargain now, and probably even more so on days like today when there was a lot of action in SFMI. I'm sure SFMI is flashing "buy" on a lot of the screening programs, and it has gotten even farther ahead of GHDC. FYI, I own a boatload of both. I also trade a few percent of my shares back and forth between SFMI and GHDC to take advantage of changes in the price ratio. But I wouldn't worry about GHDC lagging. It will catch up to where it should be eventually, especially once revenue starts coming in and numbers come out. All IMHO, of course, so be sure to do your own due diligence!
