Mostly correct — QQQ and SPY both closed at +0.1% (QQQ $584.98, SPY $655.83), showing QQQ underperformed by 0% intraday/close, which is within the >0.3% underperformance threshold technically unmet by closing data, but the thesis about divergent mega-cap performance was partially validated: META -0.82%, AMZN -0.38%, GOOGL -0.54% (down) vs MSFT +1.1%, NVDA +0.9% (up). Directional thesis sound but margin of underperformance fell short of 0.3% threshold at close.
