• Pure Omissions After Macquarie

  Where courts now draw the Rule 10b-5(b) line between actionable half-truths and non-actionable pure omissions after Macquarie v. Moab Partners — from the Sixth Circuit’s reclassification of half-truths as misrepresentations to district courts sorting redactions and silence at the motion-to-dismiss stage.

• Price Impact at Class Certification

  Recent decisions applying Goldman Sachs v. Arkansas Teacher Retirement System’s genericness framework at class certification — who bears the burden on price impact, when a misstatement/disclosure mismatch defeats the inflation-maintenance inference, and why the same test denied certification in one 2026 case and granted it in another.

• Section 11 Tracing After Slack

  How courts apply Slack Technologies v. Pirani’s requirement that § 11 plaintiffs trace their shares to the challenged registration statement — the Ninth Circuit’s rejection of statistical tracing and burden-shifting on remand, and why de-SPAC investors who receive newly registered shares in the merger exchange can still plead standing.

• Loss Causation Theories

  The two pathways for pleading loss causation after Dura Pharmaceuticals v. Broudo — the Eleventh Circuit’s market-saturation standard for partial corrective disclosures, and the Second Circuit’s zone-of-risk screen for losses pleaded as the materialization of a concealed risk.

• Forward-Looking Statement Safe Harbor

• Scheme Liability After Lorenzo

  How courts apply Lorenzo v. SEC’s dissemination theory to defendants who never "made" a misstatement under Janus — the Second Circuit’s Rio Tinto "something extra" requirement, and a 2026 decision sorting board deception and document redaction from merely being copied on an email.
