The evidence · per-firm event-study battery
Did the market price the Texas move?
Bottom line. Dillard's per-firm event-study battery is pending the canonical run. Canonical event date is 2025-07-22 — one trading day after the July 21, 2025 announcement 8-K filed after market close (20:16 ET), per the project's pre-registered after-close convention. The methodology framework is invariant; the data is firm-specific. See /methodology.
The pre-registered event-date convention
Dillard's announcement 8-K was filed July 21, 2025 at 20:16 ET — after market close. The project's pre-registration assigns the canonical event date T0 to the next trading day (July 22, 2025) so that intraday price reaction to after-close announcements is captured in Day-0 windows. The convention is documented in 06_PREREGISTRATION/ and applies uniformly across the cohort.

- Figure 9 — TSR. Total shareholder return from announcement through current. [PENDING]
The 18-cell core battery (pending per-firm run)
Three benchmarks × six windows. Dillard's results: [DATA PENDING: per-firm run]. Department-store sector context: the announcement coincided with a soft Q2 2025 results-of-operations narrative across the sector; the stress tests on /stress_tests separate redomiciliation-specific price movement from sector-wide retailer dispersion that quarter.
