Spin-off dislocation — literature and claim boundary

Research state: source review only; no market returns opened.

Economic hypothesis

A completed corporate separation can create temporary price pressure and information frictions. The distributed child may be too small, outside an investor mandate, absent from an index, or hard to value as a standalone company; the parent may simultaneously become a different exposure. The candidate is therefore a residualized, implementation-aware parent/child event family—not a claim that every announced separation earns an abnormal return.

The mechanism must be separated from size, value, momentum, post-earnings drift, index deletion, completed repurchase/issuance, and generic event risk. Any future return identity must use terms known at SEC acceptance time and must retain cancellations, delayed distributions, when-issued trading failures, missing opens, halts, fractional-share cash, basis allocation, and delistings.

Prior evidence and limitations

  • Cusatis, Miles, and Woolridge (1993), Restructuring through spinoffs, reports long-horizon abnormal performance for parents and children in an older US sample. The age of the sample, benchmark sensitivity, and long-horizon inference make it a prior—not a usable expected return. DOI: https://doi.org/10.1016/0304-405X(93)90009-Z
  • Desai and Jain (1999), Firm performance and focus, links post-spin performance to changes in corporate focus. That is an economic conditioning story, but focus labels are ex-post unless reconstructed from contemporaneous segment disclosures. DOI: https://doi.org/10.1016/S0304-405X(99)00032-X
  • Veld and Veld-Merkoulova (2004), Do spin-offs really create value? The European case, provides an out-of-US comparison and underscores that institutional setting and sample construction matter. DOI: https://doi.org/10.1016/S0378-4266(03)00157-9

These studies do not establish a modern executable sleeve. They generally do not model current opening-auction impact, when-issued liquidity, borrow, fractional distributions, tax basis, corporate-action revisions, or an untouched post-publication holdout at ALPHAC standards.

Official-source boundary

The SEC Form 10 registration statement is the initial discovery spine for exchange-registered children. Official quarterly EDGAR full indexes provide an append-only, issuer-independent list of 10-12B and 10-12B/A filings; individual filing indexes later provide acceptance timestamps and document lineage. Form 10 is not synonymous with a spin-off, so registration rows are candidates only. IPO-like registrations, reorganizations without a pro-rata distribution, and filings without a parent/child separation must be rejected by a separately frozen document audit.

Research implication

Historical positive-return claims are not copied into ALPHAC. The first admissible work is source lineage, followed by blind document-schema accuracy, then a separately preregistered return test. Failure at any stage is published; parameter changes cannot rescue the same trial.
