The weekly returns of select commodities, a set of agricultural, metals and energy products based on their spot prices are calculated to look at the
performance of commodities as an investment alternative. There are a number of factors that affect the returns of the commodities which not
only emanate from the domestic front but also reflect the global demand-supply equations. While it is true that the returns delivered in the past
are not a reflection or indication of the returns that would accrue in the future, it is nevertheless interesting to compare the same and analyze
these differences.
