First Trust ISE Global Wind Energy Index Fund ETF - USD Share Price

First Trust Global Wind Energy ETF is an exchange-traded fund. The investment objective of the Fund is to seek investment results that correspond generally to the price and yield, before the Fund's fees and expenses, of an equity index called the ISE Global Wind Energy Index. The index uses a modified market capitalization weighted methodology for each group of companies. The methodology organizes the companies into quintiles based upon their market capitalization. The quintiles containing larger market capitalization companies receive a higher weight than those quintiles containing small market capitalization companies.The resulting weight distribution prevents a few large companies from dominating the index while allowing smaller companies to adequately influence index performance.The companies are equally-weighted within each quintile.
