XSEP aims to provide approximately 2x any positive price returns of the S&P 500 ETF with a predetermined cap. The fund uses options in an effort to moderate losses over a one-year period starting each September. Using SPY is a slightly different approach than using S&P 500 index flex options, what is gained in favorable tax treatment may be lost in higher expense. The fund foregoes some upside return on SPY, in exchange for preventing realization of the first 15% of its losses. The upside cap is determined at each reset and will fluctuate, depending on market conditions. Investors who buy XSEP shares at any other time than the annual reset day may have a very different protection level and buffer zone. The issuer publishes effective interim levels daily on its website. The fund must be held to the end of the period to pursue the intended results. The targeted buffers and caps do not include the funds expense ratio. The fund is actively managed and uses flex options exclusively.
