What? How? By moving out of Massachusetts? I could understand banning such a speculative stock for e.g. pension funds or whatever, but blocking private individuals from buying with their own money seems insane.
They IPO'd in 1980, yet their stock price was below the IPO price for the majority of 1980-1987.
It also fell to its IPO price for an extended period of time between 1996-1998.
You hypothetically could have waited 20 years after the IPO before investing without giving up theoretical gains.
