During a recent Investools seminar the guy running the presentation mentioned something which has been said before "insiders sell stocks of their companies for many reasons, but only buy their own stock for one reason-they think it's going up!" ok, sounds good right? When I hear that statement, the question that comes to my mind is "so is that a good indicator that the stock is or will move higher?" Anyone ever research this at all? I am interested in knowing what kind of correlation, if any, between insider buying and subsequent stock price. I have a feeling that any price movement is immediately after the purchases (less than 1 month) and by the time you catch wind of the insider buying, the stock price has already adjusted upward thus making it no better than just simply observing the stock price movement and making a decision on that alone.
