The fund is passively managed to provide broad exposure to the Canadian oil & gas market, which includes drilling, marketing, production, equipment, and services. To be eligible for inclusion, companies should be TSX-listed and must meet investability and liquidity requirements, including a minimum market capitalization of CAD 7 billion. The index weights the resulting portfolio equally, instead of by market-cap, which lowers single-name blow-up risk and may cause a tilt to smaller firms. The index is reconstituted on a semi-annual basis.
