Yeah it's possible for sure. There seem to be two very polarized opinions on that one in the wider investment community and they both make good points.
One thing I can't see is gold dropping back greatly in the next couple of years - there is simply too much demand and not enough supply, regardless of whether people think it is good value or worth owning or not.
Even at this current price (or even lower albeit not significantly lower) SBL and the other junior gold companies that are near production could still easily forge out a really good business in the next few years.
I do tend to think that gold is going to rise further (how much is anyone's guess) and certainly don't think it is near a bubble yet. When your friends who know nothing about investing are buying gold, that is the time to run for the hills.
