MARS is trading at $24.87, up +9.03% after hours, with no specific late-breaking announcement or holding earnings identified to explain the jump.

  • The regular session closed at $22.83, down 3.43%; the after-hours rebound follows a steep seven-day decline.
  • On October 14, hotter-than-expected September CPI—3.7% year over year versus 3.6% expected—lifted Treasury yields and pressured stocks, especially technology shares. That broader risk-off backdrop helps explain the session decline, but does not establish the cause of the after-hours reversal.
