usually companies identify people with material nonpublic information (aka insider information), you will know for sure whether or not you're on that list, its one of the biggest jobs for the equity / legal counsel at public companies.   
  
 If you are not on that list you are **still** advised to be careful and mindful of insider trading laws, but for most average joe's and their $1000 portfolios its a nonissue.
