I'm pretty sure the loan they're chasing to develop SdV will first require a HKSE listing, which will first require a successful merger between GXY and GMM. I think all these things need to happen, or at least be guaranteed to happen, before SdV plans are released. Remember, GXY doesn't exactly have a spotless financial history, and I think current management is in a renewed position of proving itself as a safe place to park a great wad of cash. For that reason, I don't think they'll be trumpeting any SdV plans until the merger is a given. And if the merger is a given, I think they'll let that news run for a while before they release the SdV bomb.
I am a little concerned about the 80% acceptance requirement for the merger - this is quite a high number to chase. My concern is not that people will reject the merger, my concern is that people are typically lazy and I think many small holders simply won't follow the vote through. Hopefully GMM is held in large amounts by a few, than in small amounts by a lot.
All that aside, price action looks exceptionally resilient despite the low daily volumes, and large sell side clouds. It is heart attack material if you're constantly checking the price. I think the best thing to do is just turn off the computer for a month, turn it back on and then say hello to new highs.
