SQQQ, an inverse leveraged ETF, fails Shariah compliance due to its speculative structure involving short-selling, derivatives, and interest-based leverage, which introduce elements of gharar, maysir, and riba. Financial ratios are inapplicable due to the ETF's non-traditional balance sheet, but business activity screening disqualifies it entirely. No inclusion in major Shariah indices confirms non-compliance across global standards. Investors should avoid SQQQ for Shariah portfolios, opting for compliant equity or sukuk alternatives. Purification is not applicable given the inherent non-compliance.
