Waiting for the outcome is the sensible thing to do ... no doubt about that.
I have been a bit dubious the Swiss vote [if yes] would make much impact, but as it draws near I am thinking it might actually be important.
A no vote will confirm the status quo and as such it should not provide extra negative sentiment to gold. A yes vote is a direct confrontation to the authority of central banks. In terms of having a 'flutter' the odds favour a gamble imo. [all 'armchair general' stuff on my part ... I do not directly trade gold]
