Market closed up solidly on AI infrastructure investment and easing geopolitical risk.

The market closed up solidly with Technology and Utilities leading, driven by AI infrastructure investment and easing geopolitical risk, while Financials and Industrials lagged due to tightening credit conditions. The forces behind the market are split, and fresh geopolitical escalation may interrupt the current trend. The next session will be influenced by how geopolitical risk plays out.

Why it mattered: Today's close sets up a fragile pre-market environment due to conflicting geopolitical signals.

What we said to watch

The reaction to fresh geopolitical escalation headlines when the market reopens.

This is the reading as it was written on the day. It has not been edited with hindsight, and it may have turned out to be wrong.
