Both alternative energy and Africa represent fertile terrain for investment growth -- or so reasoned some exchange-traded fund managers earlier this year. But new ETFs focusing on those themes have yet to pay off. The accompanying table of five recently created ETFs targeting the realm of alternative energy and two with investments in Africa and the Middle East shows that the new offerings have yet to break out from the pack during the depressing autumn of 2008. With more than 800 ETFs now competing for investor attention, new offerings by the industry usually reflect what money managers consider the new "trendy" areas of the investment milieu. As often as not, by the time the investment fashion police identify an area as "the next new thing," the investment trend has peaked and investors find themselves dressed in last year's portfolio trappings. But this new batch of tony ETFs represents the possibility of longer life spans. Few would quarrel with the reasoning that the alternative energy trend is still in its infancy. Similarly, the Africa/Middle East region is undeniably the least -- and possibly last -- exploited investment region left on earth. The only fund on the list to outperform the S&P 500 total-return index over the past three months was the iPath Barclays Capital Global Carbon Index Total Return Fund ( GRN), which retreated only 14.45% while the S&P tumbled 23.11%. None of the other funds in the list of seven was able to better the S&P gauge during the October bloodletting.
