I wonder how much insider trading really happens, even somewhat innocently. Someone who isn't me (SWIM) was once upon a time casually talking to his colleague (who has insider info) about their company stock. SWIM wanted to sell some of his shares before earning report as they often tanked. Colleague said that the numbers will be good as they want to make the new CEO to look good. SWIM kept his stock past the ER and indeed it mooned. I think this may be insider trading, but also it may be happening all the time everywhere, most of the time unintentionally...
