Global metals producer Glencore Xstrata Plc is also engaged in the business of commodities supply. Today, in Johannesburg, it would make its market debut and according to Investec Asset Management, would draw strong demand for its stock.

According to Investec Asset Management's hesd of commodities for frontier and emerging markets Hanre Rossouw, "In terms of diversification, it offers something pretty unique. You've got two thirds exposure to something you don't really get in the South African market." Rossouq was referring to Glencore's copper mining and marketing businesses.

While the primary listing of Glencore remains in London and a secondary listing in Hong Kong, Glencore CEO Ivan Glasenberg had obtained approval from Xstrata Plc investors for the merger of the companies last November 2012. The Johannesburg born CEO was instrumental in creating the fourth largest mining group in the world with operations in over fifty countries, and interests in South African platinym, chrome and coal.

In a communique released last September, "Africa is an important and growing market for the group and South Africa has a strong institutional base." One of the provisions in the Johannesburg listing is that South African investors are allowed to purchase Glencore Johannesburg stock without the same being counted against foreign ownership cap limits currently in force.

Glencore, according to a November 11 presentation, is said to be one of the most diversified amongst the major mining companies in the world. Rio Tinto had accounted for nearly 89% of first half earnings, BHP Billiton for is part had 52% while Anglo American Plc had 48% of its earnings from iron ore. For its part, Glencore's biggest metals contributor copper, accounting for 30% of its earnings before taxes.
