UK inflation accelerates to 2.9% in July amid Middle East energy shock FT

Technical Analysis

Equity leadership split: The S&P 500 (SPY) held up better than both the Nasdaq 100 (QQQ) and the Russell 2000 (IWM), while sector breadth showed four advancers versus seven decliners, indicating that weakness was more common than strength even as the broad index outperformed the tech heavy proxy. Within sectors, Energy (XLE) led and Technology (XLK) lagged, matching the index level split between the broad market and the tech concentrated benchmark.

Aligned sector signs: Financials (XLF), Health Care (XLV), Consumer Staples (XLP), and Energy (XLE) share positive sign alignment across today, one week, and one month, while Communication Services (XLC) is the only sector with negative alignment across all three horizons, setting up a clear relative strength versus relative weakness pairing to track. The Treasury curve is upward sloping with the 10 year yield above the 2 year yield, but because that curve snapshot does not match the completed equity session date, the next observation to monitor is whether a same session curve reading coincides with continued leadership from the positively aligned sectors and continued lagging from the negatively aligned one.

The U.S. banned Nvidia's best chips from going to China. Now it's trying to close a crucial loophole CNBC

Despite U.S. export restrictions on Nvidia’s most advanced AI chips, several Chinese AI firms have reportedly accessed equivalent computing power remotely through data centers in Southeast Asia, including Thailand, Malaysia and Japan. Analysts cited in the report say current U.S. controls focus on physical chip shipments and generally do not cover remote cloud-based access when the Chinese customer does not own the hardware. U.S. lawmakers are discussing legislation such as the Remote Access Security Act to extend export controls to cloud access, though the article notes practical and procedural hurdles before any changes would take effect.
