The fund seeks investment results that correspond to 2x inverse of the daily performance of its underlying index, which is designed to measure the performance of the Canadian energy sector. Securities, however, that belong to any of the following classifications are excluded from the index: (i) Oil & Gas Refining & Marketing, (ii) Oil & Gas Storage & Transportation, and (iii) Coal & Consumable Fuels. The fund is market-cap-weighted, with individual constituents capped at 25% of the index weight. As a levered fund, it is not a buy-and-hold investment and should not be expected to provide index leverage returns greater than a one-day period.
