Is Poz driven by speculative forces in the same way as Pog and Poo?

I assumed industrial demand and supply were by far the most significant factors establishing trend direction (as opposed to gold where the buying and selling of futures determines where things go)

I ask because if this is the case (i.e. price is moving primarily due to factors re zinc availability and industrial demand from China and elsewhere) TA really provides v little guidance on emerging price trends.
