This week's PortfolioDirect/resources investment report rated four companies: Bannerman Resources (BMN), Horizon Oil (HZN), Nexus Energy (NXS) and Metals Australia (MLS). Horizon Oil was given a portfolio grade rating indicating it would be a suitable addition to a resources sector portfolio. Of the two Namibian uranium plays - Bannerman Resources and Metals Australia - Bannerman was considered the best positioned to take advantage of a change in uranium market conditions with a project almost 'shovel-ready'. However, the PortfolioDirect approach places a heavy emphasis on investment opportunity cost which would mitigate against an exposure to Bannerman at this point in the cycle. The PortfolioDirect ratings are available to assist investment professionals in advising their clients. The latest monthly ratings summary (for November) can be downloaded here: (VIEW LINK).
