About this ETF
The Roundhill COST WeeklyPay ETF (COSW) is designed to offer investors a blend of regular weekly income and moderately enhanced exposure to the weekly price movements of COST stock. It achieves this objective by investing in total return swap agreements and directly in COST common stock, collectively targeting approximately 120% of the underlying stock's calendar week return. This effectively provides 1.2x leveraged exposure to a single company's shares. Shareholders can expect weekly distribution payments. To secure its investments, the fund allocates capital to short-term US Treasurys and money market funds as collateral. Investors should be aware that COSW introduces heightened volatility compared to traditional ETFs. This increased risk stems from its lack of diversification across multiple assets and its strategic use of leverage. It's crucial to understand that investing in COSW does not equate to a direct investment in the underlying COST stock itself. Consequently, the strategy is fully exposed to all potential capital losses should COST shares decline in value. A significant weekly price drop of 83.33% in COST's share price could result in the total loss of the fund's value within a single week. This fund functions as a short-term, tactical instrument. Therefore, it is best suited for investors who possess a high tolerance for risk and operate with a short-term investment horizon.
