The model's market view
October 27 session featured earnings-driven extremes, with strong beats in equipment rental and biotech lifting select names while guidance cuts and production delays pressured water infrastructure and aerospace; energy refiners also weakened on softer oil. Expect some directional follow-through on the largest liquid moves into the Fed decision day, though overall market remains mixed.
