There are two could-be catalysts:
1. POO. If poo does cross the $60 line, then no one can stop STO crossing the $6 line. That's the good thing to buy commodity stocks. Many instos are able to manipulate a specific stock on ASX, but they cannot do the same on poo.
2. The shorts are increasing and so is the SP. A stop-loss line or short squeezing could be a catalyst, but I do not know when.
