Unfortunately, the campaign on the "No" side seems to be winning, polls are showing, so there is now little hope this issue by itself will save/support POG
That doesn't answer your question, though. From what I read, should the referendum pass, POG may rise about 20 percent almost immediadely, and continue as the Swiss National Bank keeps buying over the coming several years. ...doesn't now look as if that will happen. Too may people profiting from a weak Franc.
