Experience and statistics shows that directors buying doesnt mean a hill of beans in the longer view, it does help short term sentiment. Often used to pull more suckers in ( ie '5 directors buy some cheap shares over a couple of weeks in a penny share, they must know something , everyone piles in).
In this case with Nigel's 200K, I don't accept that its a cynical exercise, its because he is sure that events will lead to a higher price for his stock next year. This shows he knows that at late December we are still on a bullish track sales wise.
Sticking with RTD.
PS the City are often wrong, Institutions are very often wrong. Even more so than Directos who buy shares , or fail to. Use charts and fundimentals to judge shares by. Seek bargains ... RTD could be a bargain at the moment.
