"Quite Period". Does anybody know the SEC rule at to the "quite period" before earnings announcements. It's been my understanding that, if a company is going to have a drastic change vis-a-vis prior guidance, they must go public before they enter the "quite period", and I thought this was 15 days prior to scheduled announcement. Therefore, once you get within 15 days of earnings, and you have not had an announcement, you (probably/shouldn't) won't have actual earnings that vary much, up or down, from guidance. Can someone validate or correct the above?? Thanks.
