The investment seeks to provide returns that outperform the large-capitalization U.S. equity market on a risk-adjusted basis. The fund seeks to achieve its objective by estimating the direction and magnitude of S&P 500 Index volatility based on the movement of the CBOE Volatility Index® (the VIX® Index). Under normal market conditions, its baseline exposure each day to the S&P 500 Index is approximately 90%, which the fund's portfolio managers then adjust based on a quantitative model and analysis of the movement of the VIX Index. Its exposure may be significantly greater or less than 90% at any given time. The fund is non-diversified.
