I'm sure it is overvalued but that doesn't mean it will drop any time soon. However when it does I'm sure it will drop hard and fast just like the Euro/shares etc on a bad day.. Until it does I'll stay in and keep adding positions and moving my stop loss to lock in more profits.
Things are so unsure at the moment with the Euro mess, the US losing it's safe haven status, the Swiss and Japanese central banks taking whatever measures they can to weaken their currencies while people are piling into them...
Gold is the only sure safe haven people seem to have in these highly volatile and uncertain times. Yes it's massively overvalued but I wouldn't go picking tops and trend reversals just get. There are a few fat ladies in Europe and the US yet to start singing..
Just my outlook... I'm long gold with stops in place to lock in profits
