The bubble index for the price of gold, shown in the following figures, indicates that gold is undergoing a bubble. Based on my data, although limited to 2001-2013 the bubble index has traveled continuously upward. If I can find better weekly data for the price of gold, then this upward trend can be properly put into perspective. Or, the code may not be properly designed for commodity prices. The price data is not inflation adjusted.
