Under normal market conditions, this fund allocates at least 80% of its total capital to investments that either directly comprise its underlying index or possess equivalent economic attributes. The index itself is designed to track a cash-secured put option writing strategy, which involves issuing S&P 500 Index put options (referred to as "SPX Puts") and subsequently placing the proceeds from these option premiums into short-term U.S. Treasury bills, specifically those maturing in one or three months. This fund operates without adhering to diversification requirements.
