Don't think it's really fluctuating at all at the moment. Obviously it dropped a lot earlier this year, and a series of mini-recoveries each were followed by another dip, which brings us to where we are now - we're at the same bottom that has been reached several times already this year, except now momentum has run out and we have had a quite long period of relative stability.
It does look like we are starting to gather strength for the new bull-run, but for now at least the volatility has diminished considerably.
