The Fund will purchase call options and sell (write) put options on the S&P 500 Price Index or an ETF that tracks the S&P 500 Price Index on each Initial Investment Day with an expiration on the next Roll Date. An option gives the purchaser of the option the right to purchase (for a call option) or sell (for a put option) the underlying asset (or deliver cash equal to the value of an underlying index) at a specified price (strike price). In the event the underlying asset declines in value, the value of a put option will generally increase (and the value of a call option will generally decrease and may end up worthless), and in the event the underlying asset appreciates in value, the value of a put option will generally decrease and may end up worthless (and the value of a call option will generally increase).
