The sharp pre-market increase in Rocket Lab's stock price is a direct result of a major positive catalyst announced late Thursday.

  • The company is set to be added to the prestigious Nasdaq-100 Index ($NDX), a move announced by Nasdaq after the market closed on June 11.
  • The inclusion will become effective before the market opens on Monday, June 22, 2026.
  • Being added to the index is a significant milestone that typically boosts demand for a stock from the many passive funds and ETFs that track the Nasdaq-100.
