Open interest is distinct from volume: volume counts how many contracts are traded in a session, while open interest counts how many remain open at the end of the day. Rising COSW options open interest alongside rising volume suggests new positions are being built, while falling open interest signals positions are being closed. Heavy open interest at specific strikes often acts as a magnet near expiration and can hint at where dealers and large traders expect Roundhill COST WeeklyPay ETF to settle.

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.

Pin risk into expiration, dealer positioning, liquidity checks for large orders — all of it starts with knowing where COSW open interest is concentrated.
