Situation Awareness: Cautious. Wednesday’s tape was a broadening rally masked by modest headline gains — the S&P 500 closed +0.21% at 7707.98, the Nasdaq +0.16% at 26352.12, and the Dow +0.22% at 53463.05, but the S&P 500 Equal Weighted Index jumped +1.0% as rate-sensitive groups, health care and materials led while semiconductors sank again (PHLX Semi -2.1%). The defining catalysts: Moderna’s (MRNA) +177% cancer-vaccine moonshot and the Treasury’s decision to at least double long-dated buyback operations, easing the 10-yr to 4.65%. Trade mode for tomorrow: selective and constructive — lean into the rotation winners (health care, materials, homebuilders) but respect ongoing chip weakness. Regime context — 54.0% of stocks closed above their 40-day SMA (vs 56.3% prior day, regime held at Cautious), and the 4% Bull/Bear gauge shows 403 bulls vs. 134 bears. The 5-day trend is choppy — Tuesday’s momentum-driven washout was followed by Wednesday’s broad-based bounce, signaling a rotation rather than a directional trend.
