etf_composite_score_current · composite_score, confidence, coverage_pct, expenses_score, performance_scoreetf_universe · asset_class, aum_usd, fund_type, inception_date, issuer, name, tickerGraniteShares YieldBOOST Biotech ETF is an exchange-traded fund designed to generate weekly income through an options-based strategy focused on the biotechnology sector. The fund sells put options on leveraged ETFs that track the S&P Biotechnology Select Industry Index, aiming to achieve three times the income generated from these option sales. The fund targets investors seeking regular income distributions from one of the market's most dynamic sectors, which experiences elevated implied volatility driven by clinical trial outcomes, regulatory decisions, and merger and acquisition activity. Rather than investing directly in biotechnology companies, the fund leverages options premiums to provide its weekly distribution strategy. The fund structure includes downside protection mechanisms and is designed specifically for income-focused investors seeking exposure to the biotechnology industry through a premium-collection approach.
