QQQ and SPY hold opening gains as mixed data, oil security and Nvidia news compete for attention

QQQ finished 1.09% above the previous close and SPY gained 0.98%, with most of the advance already present at the regular-session open. Trading then stayed comparatively steady. The New York manufacturing index missed its estimate, while U.S. industrial production rose and the housing index edged above expectations. Oil-supply coordination and fresh Iran threats kept Hormuz risk in focus. Nvidia's seven-chip production announcement added a technology theme, while QQQ ended 0.11 percentage points ahead of SPY.
