Clean Energy Fuels is trading at $1.68, up 5.18% in pre-market; the cause of the September 28 move remains unclear.

  • The latest company announcement found was a September 24 sale of $30.7 million in tax credits. Available evidence does not link it to this morning’s gain.
  • Broader markets are weaker in the supplied context, so the move does not appear to track that direction.
