March 15, 2021 With energy ranking as the best-performing sector to start 2021, some investors are considering momentum as a way of accessing the high-flying group. The PXI seeks to track the investment results of the Dorsey Wright® Energy Technical Leaders Index. The underlying index is composed of at least 30 securities of companies in the energy sector that have powerful relative strength or ‘momentum’ characteristics. Using the relative strength index, investors can identify areas with positive forward momentum. Relative strength measures a stock’s performance in relation to its peers. A rosier outlook for economic growth and oil demand could fuel gains in energy sector-related exchange traded funds this year.
