NRGD is a leveraged take on US Oil and Gas industry and tracks three times the inverse of its underlying index - Solactive MicroSectors U.S. Big Oil Index. The index selects the 10 most liquid stocks from the Solactive GBS United States Large & Mid Cap Index, screened for market cap and liquidity. Specifically, those with above USD 1 billion free-float market cap and those with minimum of 1-month and 6-month ADTV above USD 25 million are included. The index is weighted equally and TRBC Oil & Gas Industry classification is used. Its worth noting that the product isnt designed for long-term investors. The fund rebalances daily. As a result, compounding and path dependency make its long-term returns difficult to predict when compared with its underlying index.
