Director buying will come in the future and will show all director trades for a given stock updated daily. Director buying is the closest thing to insider trading that's legally available. When directors are buying large quantities of their own stock and hopefully adding to already large quantities of their own stock there is normally a reason. Do you think a director of a company knows what's going on within the company more than the general public does?
When a stock can be found that has attractive fundamentals, has directors buying their own stock and then has financial institutions buying in as well this is almost always a great time to buy.
