Ron I agree, it can be very subjective at best. Especially when you are talking a couple thousand shares or dollars here and there. With companies facing new yr lows on a daily basis one can say that insiders buying could be looked upon as "supportive" at best. Otherwise the legal aspects of insider trading may come home to roost. There are restrictions on when insdiers can buy or sell a stock. Front running is frowned upon if it can be proven.
The eyebrow raisers are the biggies or the huge dollar moves. Mass entry or mess exodus can be meaningful and insightful
That particular freebee 10 transaction snapshot is just that. One has to usually look at the bigger picture for something more useful and informative.
