The dominant narrative from the previous cycle—Iran de-escalation—remains stable with no new counter-signals in this window. However, several high-significance after-hours earnings and guidance moves have emerged, creating actionable sector-level signals. Zscaler (ZS) plunged ~16% after issuing Q4 revenue guidance below consensus, dragging down cybersecurity peers Palo Alto Networks (PANW) and CrowdStrike (CRWD) by ~2% in sympathy. This is a bearish signal for the cybersecurity sector. Conversely, Semtech (SMTC) surged 8% on strong Q1 results and upbeat guidance, signaling strength in the semiconductor space. Micron (MU) joined the $1 trillion market cap club, up 19.3%, driven by AI demand, reinforcing the AI/semiconductor bull thesis. On the macro front, Russia is considering export restrictions on diesel and jet fuel after drone strikes crippled refinery capacity, which could tighten global fuel supplies and support oil prices. The U.S. Trade Representative stated the administration's view on Chinese investment has not changed, maintaining a cautious stance on trade. A major chemical explosion at a Nippon facility in Longview, Washington, has caused casualties and missing persons, which may impact local industrial operations. The S&P 500 and Nasdaq hit record closing highs on AI optimism, but consumer spending data shows 2 of 3 Americans cutting back, creating a divergence between market highs and Main Street weakness.
