International Journal of Management Practice (IJMP), Vol. 10, No. 3, 2017

Abstract: The present paper has bifocal objectives. First, the paper explores the time series dynamics of the industrial and precious metals commodities futures contract traded on the India's largest commodity exchange, Multi Commodity Exchange of India. Second, the paper focuses on the causality dynamics of industrial and precious metals. No such study has been undertaken on the Indian commodity bourses. In addition, it focuses on the existence of the long-term co-integration relationship - if any - between these specific categories of commodities. Amid sharp rises in both commodity prices and commodity investing, many commentators have wondered whether commodities nowadays move in sync with traditional asset classes like equity, gold, crude oil and Forex. The rationale behind diversification contends that a portfolio of different kinds of investments will, on average, yield higher returns and pose a lower risk than any individual investment found within the portfolio. The paper tries to identify the long run relation-ship of industrial and precious metals with its traditional investment counterparts like Crude Oil prices, USDINR exchange rates, and Nifty 50 index. For same, the paper has utilised advance Granger causality and Johansen co-integration tests. Our results imply that industrial and precious metals may not able to provide the benefits of diversification all the time.
