> But it's important to recognize patterns. If 3 out 5,000 employees are selling their stock in the week before earnings, it's probably just normal bill shuffling. If 3,000 out of 5,000 employees are selling their stock in the week before earnings, that probably means something far more significant. Let the market figure out what the patterns mean. I'm not saying it's impossible, or doesn't happen, but IME it's incredibly unlikely that 3k of 5k employees would know about earnings before they were anounced to the public. Corporations just don't work that way. The C*Os and some of the finance team will know, but >95% of the employees will find out when the public finds out.
