The fund invests in North American stocks of companies in the consumer discretionary sector to provide monthly cash distributions. Under the FactSet industry classifications, a company must identify as an airline, REIT, casinos and gaming, and hotels, resorts, and cruise line firm. The selection process begins by applying two typical screens on the GBS index universe. Eligible companies must have at least 2 million USD average daily trades over the last six months and at least seven million USD free-float market capitalization. The remaining securities are reduced further by requiring each companys business description to contain at least one keyword from the following: airline, passenger, travel, resort, hotel, cruise, travel, and others. The fund selects the top 30 companies by market cap. Each month the manager writes covered-call options on no more than 33% of the market-cap weighted portfolio. The theory is that option writing adds value by cutting volatility and improving returns. The index rebalances semi-annually.
