> **Quick answer:** The week of May 18, 2026 is arguably the most catalystloaded trading week of the year. Monday opens with a jury beginning deliberations in the landmark Musk v.

Wednesday is a triple-threat: Nvidia reports Q1 FY2027 earnings after the bell (consensus: $78.8B revenue), Meta executes its 8,000-person layoff wave, and FOMC minutes drop. SpaceX's public S-1 filing may land any day this week. Add LIRR strike economic drag and geopolitical market pressure — including the killing of Hamas military chief Izz al-Din al-Haddad on Saturday — and markets have no shortage of price-moving events to digest.
