About this ETF
COYY aims to pay weekly distributions based on a put option writing strategy. The ETF is actively managed, holding indirect exposure to COIN-leveraged ETFs. It seeks 200% of the daily percentage change of the COIN ETF, with capped gains. Regulatory constraints on risk might force strategy adjustments. The fund does not guarantee success and excludes direct investment in the COIN ETF, leaving potential losses without premium offset. The underlying COIN ETF targets 2x the daily stock performance, with long-term returns affected by daily rebalancing and compounding. The funds exposure ties closely to the financial exchanges and data industry due to the single underlying stock focus.

Guided help: AUM is fund size. The expense ratio is the yearly cost baked into returns. NAV is the value of what the fund owns per share; the market price can sit slightly above (premium) or below (discount) it. Total return assumes distributions were reinvested. Every dataset shows its own as-of date because holdings, assets and quotes update on different schedules.
