New Sustainable Transportation ETF to be Launched on NASDAQ Invesco PowerShares Capital Management LLC plans to list its PowerShares Global Progressive Transportation Portfolio on the NASDAQ Stock Market on September 18, 2008. Worldwide economic growth has increased demand for transportation solutions, but in most cases those solutions have not been matched by sustainable improvements in infrastructure. Sustainable transportation meets the needs of society without sacrificing ecological values. To be traded under the ticker PTRP, the portfolio is an exchange-traded fund (ETF) that is based on the Wilder NASDAQ OMX Global Energy Efficient Transport Index. An index-based exchange-traded fund seeks to replicate the movements of an index of a financial market. The Wilder Index tracks innovative and energy efficient transportation by focusing on businesses that are engaged in cleaner and improved means of transporting goods and people. It includes a global group of companies engaged in four focus areas: alternative vehicles; rail and subway systems; sea, land, air and intermodal; and transport innovation.
