“Buy or sell it with knowledge of insider information.”
Granted that the CEO ALWAYS has inside information, how then is he to sell his stock?
What about the engineer that designs the new widget? Is he forbidden to trade the company stock?
Very carefully.
You can not sell or buy before a major event that will change your stock price dramatically.
You can only sell after the news that the new widget causes children to develop purple spots breaks, not before.
You only can buy after the news breaks that the widget cures the heartbreak of psoriasis, not before.
Unless you have a plan where you are selling or buying a thousand shares every week for five years, then you are OK. Well as long as you are in week seventy two not week one.
