AOT Growth and Innovation ETF focuses on companies with "high growth potential based on a low marginal cost business model." AOTG's portfolio is highly concentrated, with 35.7% in AMD, NVDA, and MU, and features strong GARP and quality characteristics but quite high beta. AOTG's 75 bps expense ratio, suboptimal liquidity, and higher drawdown risk undermine its appeal relative to QQQM.
