DVQQ follows an index that tracks the performance of the Invesco QQQ ETF (QQQ) while seeking to maintain a defined annual volatility rate of 22%. On each trading day, the index measures QQQ's 21-day volatility and adjusts its exposure to the underlying ETF accordingly. If the measured short-term volatility is below the defined volatility rate, the index increases exposure to the underlying ETF using total return swaps, thereby increasing volatility. Conversely, if the short-term volatility exceeds the defined volatility rate, the index decreases exposure to the underlying ETF and utilizes cash positions to reduce volatility. The exposure to the underlying ETF varies dynamically between 0-200%. The underlying ETF, QQQ, is an investment trust that seeks to track the NASDAQ-100 Index, which includes 100 of the largest domestic and international non-financial companies listed on the Nasdaq Stock Market based on market capitalization.
