> So you think that people who have the ability to affect the value of a publicly traded good should be allowed to trade on actions that they can plan and know about in advance? Insider trading laws don't stop this from happening. People not considered "insiders" can impact the price of stock. For example, in 2007 Lululemon stocks took a temporary dive when their seaweed claim was challenged: "Not so, says the New York Times, which commissioned its own test after a Lululemon investor, who is shorting its stock, supplied the paper with lab results." That, of course, doesn't include market professionals: "Market professionals gain disproportionately from bans on insider trading because they are in a position to act on information that insiders cannot use, and can do so more quickly than any other group, including shareholders" [1] [1] https://books.google.com/books?id=l9PuCAAAQBAJ&pg=PA161&lpg=PA161&source=bl&ots=_IRz81o-U3&sig=ZMJ6tFrBXZ-a_SxvXkp5k0rKVR0&hl=en&sa=X&ved=0ahUKEwjkreK-9cnYAhVCuY8KHeKkA-8Q6AEIPDAF#v=onepage https://books.google.com/books?id=l9PuCAAAQBAJ&pg=PA161&lpg=...
