I’m not talking about legal insider trading by corporate officers that the financial press follows. I’m talking about the mistresses of executives and $2000 per hour prostitutes who heard something over pillow talk, friends at country clubs who get a tip during the golfcart ride to the 18th hole, industrial espionage operators (former spooks) who have these idiots under surveillance, low level IT staff who read the executives’ email, not for fun, but for profit, etc. etc.

The point is that LOTS of people who aren’t corporate insiders know the news before the market does. They buy before the news comes out. This happens every day.
