The Role of Agribusiness Assets in Investment Portfolios

Investment in agribusiness assets has grown significantly in recent years. The question of interest is whether including agribusiness assets in investment portfolios provide benefits. The effects of diversification by including agribusiness assets in two investment portfolios, a mixed asset portfolio and a diversified share portfolio was investigated using Markowitz’s (1952) Modern Portfolio Theory (MPT) of mean-variance optimization. To measure the performance of agribusiness assets, an index of agribusiness companies listed on the Australian Stock Exchange was used. The results of the study suggested that agribusiness assets provided some diversification benefits in both the mixed asset and diversified share portfolio. The benefits of including agribusiness assets in a mixed asset portfolio were shown to be more significant than in a diversified share portfolio. Allocations of agribusiness assets in the portfolios tended to increase with portfolio risk, up to a peak of 32.10% agribusiness assets in the mixed asset portfolio, with allocations tending to decrease with increasing risk in the diversified share portfolio, peaking at a 17.72% allocation in the minimum risk portfolio. For both the portfolios analysed, agribusiness assets entered efficient portfolios at the minimum risk portfolio.
