A relative “who works for a company” may not necessarily be “an insider”. That is, a general rank-and-file (non-management) employee with no special fiduciary responsibility, no duties connected with strategy and planning, no other special knowledge, say, of major orders, company buy-out, etc. is not “an insider”. The CEO or CFO, on the other hand, or members of the Board of Directors are prima facie “insiders”. Between those ranks, though, say “middle managers”, supervisors, people who work in Planning, Purchasing or Sales may or may not be insiders. That’s a gray area.
If the news has been announced to rank-and-file employees, for example, that the company is being sold to another firm, or that a major order has been received, or that a company shake-up is going to occur – or any other “special news” which has been announced to rank-and-file employees or to the public at large, then that is not at all “insider” information.
