The S&P 500's 0.28% decline on 8 July 2026 following Trump's Iran comment looks like headline noise rather than a genuine repricing, since futures were already up 0.34% before the next open and the Nasdaq Composite closed higher the same session; the real economic exposure sits in Gulf-linked earnings, not the US equity index.

What would prove it wrong

If S&P 500 futures give back their overnight gain and the cash index closes lower for a second consecutive session on 9 July 2026, the noise framing fails and the Iran statement is confirmed as a genuine equity risk driver.
