    Spin-offs into a different sector than the parent (pure-plays) have historically outperformed diversifying ones.

  • Tax-basis reportNone found

    A Form 8937 (basis allocation) accompanies tax-free §355 spin-offs — favorable for taxable holders.

  • Insider buying (post-spin)None recorded

    Officers/directors buying their own newly independent shares (Form 4) has historically preceded outperformance.

  • Time since spin-off3 months

    Studies find the spin-off return premium concentrates in roughly the first one to three years.
