I think Tom Winnifrith missed a cracking entry for his Dirty Dozen AIM-listed resource stocks whose share prices might head north for no good reason. Certainly, the history of Frontera (FRR) suggests so from its share price performance over the years. Plenty of Red Flags to look at here! This morning the shares are indeed on the rampage (up 168% last seen) in the wake of a board appointment RNS. As we shall see, there seems to be little reason to celebrate that, and with one “know of no reason” RNS already issued this week, I fancy another is on the way.
