The First Trust Nasdaq Oil & Gas ETF (FTXN) is an exchange-traded fund whose principal objective is to mirror the overall performance—both price appreciation and dividend yield—of the Nasdaq US Smart Oil & Gas Index. This tracking aims to reflect the index's returns before the ETF's own operational costs are factored in. To achieve this, the fund seeks to replicate the specific securities and their proportional representation within the Nasdaq US Smart Oil & Gas Index, targeting a performance correlation of at least 95% with the benchmark.
