COSW aims to combine weekly income and modest enhanced exposure to the weekly price performance of COST stock. The fund invests in total return swap agreements and COST common stock that in aggregate will return approximately 120% of the calendar week return of COST shares. Aside from providing 1.2x leveraged single-stock exposure, the fund will make weekly distribution payments to shareholders. It also invests in short-term US Treasurys and money market funds for collateral. Unlike traditional ETFs, COSW introduces added volatility due to its lack of diversification and use of leverage. Investors should note that an investment in the fund is not an investment in the underlying stock.

The strategy is subject to all potential losses if COST shares depreciate. The fund may lose all of its value if COST's share price decreases by 83.33% over the course of a week. The fund is a short-term tactical tool, meaning it is designed for investors with a high-risk tolerance and a short-term outlook.

Catalysts rarely arrive without a footprint, and COSW unusual options activity is often where that footprint shows up first.
