I pretty much agree w/ bigpic. I'm not buying anymore only because I'm full up- SFMI is by far my largest holding, partly because I also bought most of what I have under .03. The only times I sold SFMI in the past were to trade back and forth between SFMI and GHDC, but then I held only SFMI for quite a while. Recently I've picked up some GHDC, partly by selling some SFMI and partly by selling other stuff. My thinking is the same as bigpic's- SFMI and GHDC may end up merging at some point, or GHDC may work out other deals on other properties. I'm still mostly SFMI, though.
I'm not a trader, so I won't give any advice on that. As for the long haul, I think any price down here will look good as soon as news starts flowing.
