Alcoa, Chinalco 12% interest in Rio Tinto seen as savvy move for both stakeholders

Further, Alcoa and Chinalco said in a regulatory filing that they did not intend to make an offer for Rio Tinto, but they reserved the right to announce an offer or participate in an offer within the next six months, the Associated Press reported.

Savvy move

Independent stock analyst C. Leonard Bauer told BloggingStocks Friday the Alcoa/Chinalco play has all the makings of "an additional corporate move to follow, stay tuned."

"It's an ingenious move by the two. Chinalco fears a BHP Billiton buy of Rio Tinto will cut its own companies out of access to minerals, minerals that China really needs for its giga-growth economy, and Alcoa gets a stepping stone toward a larger move on Rio," Bauer said. "Alcoa already lost out when Rio Tinto bought Alcan. This is Alcoa's first-shot counter-offensive, and there most likely will be an additional move." Bauer added that he does not have a rating on Alcoa, Rio, Chinalco or BHP Billiton, and neither does he own the companies' shares.

The global mining industry is in a period of consolidation and restructuring, driven largely by surging emerging market economic growth and infrastructure development. That global growth requires mine companies big enough to supply large-demand customers, while maintaining moderate costs, requiring increased economies of scale, which leads to operational expansion and/or mergers/acquisitions.
