Arcturus Therapeutics is trading 6.62% up at $8.38, extending a volatile advance after recent gains.

  • It gained 21.88% on August 7 and 6.67% on August 11.
  • No new company-specific announcement dated August 14, 2026, was identified.
  • Investor interest may reflect the August 6 earnings update, including progress in ARCT-032 and ARCT-810, but reporting does not directly attribute the move to that news. The broader market is lower, so macro sentiment is not a clear explanation.
