Hratt,
I cannot give reason for today's move in gold. My take is that it somewhat makes sense, at least earlier today, because the Market equities were being hammered, so folks were taking their money to safety.
But, today's Market (Dow) has turned (continued higher lows and higher highs), and may actually scratch its way into the green. Making gold and the Market run together. Which then makes no sense, but that is what has been happening since October.
Another possibility: Annual/4th qtr statements have been evaluated (showing loss) and orders to get out of the Market are being given, possibly moving that money to gold. This was evident in early October (although not sure of the gold move at that time).
