So the question raised here is whether gold is overvalued. Based on five barometers the answer is a resounding yes. The article compares gold prices to the value of the S&P as opposed to the DOW which is traditionally used. Of course nobody knows for sure but people holding their gold (regardless of whether this is scrap gold, gold jewelry or other even ETF’s) and not selling gold now risk the chance of a big drop in value. What do you think of the current situation?
