TQQQ, the ProShares UltraPro QQQ ETF, seeks to deliver three times the daily performance of the NASDAQ-100 Index using derivatives and swaps, which inherently involve riba (interest), gharar (uncertainty), and maysir (gambling-like speculation). This structure renders it non-compliant with core Shariah principles across major screening methodologies. Financial ratios cannot be traditionally applied due to the ETF's non-operational balance sheet, but qualitative business activity screening disqualifies it. No inclusion in major Shariah indices confirms its exclusion from compliant portfolios. Investors seeking exposure to technology sectors should consider Shariah-screened alternatives like the Wahed FTSE USA Shariah ETF (HLAL).
