QQQ slips 0.01% while SPY edges up 0.02% amid housing data and tech scrutiny

QQQ finished essentially flat, down 0.01%, while SPY edged up 0.02% and led by 0.02 percentage points. The August NAHB Housing Market Index missed its estimate. Microsoft opened an urgent probe into reported military use of its technology, Oracle selected GPT-5 for SaaS applications, and a reported potential U.S. government stake in Intel kept technology policy in focus. A White House meeting on Ukraine added a geopolitical backdrop, while S&P maintained the U.S. AA+ sovereign rating late Monday.
