It will be halted for at last a week, and it could be a lot longer no date has been set either by newl or Nasdaq, nobody knows exactly when the halt will be removed, if stock manipulation occurred then it will take months, it all depends on the Nasdaq findings, Nasdaq intentions are to protect shareholders but anybody with a position long or short is frozen with their monies tied up. If all Nasdaq wants is information to clarify things it could open up by the end of this week, once again if improprieties occurred it could take forever.
all of my posts are my own opinion, and should not be taken as investment advise.
