From a supply and demand perspective, tin is in deficit and most analysts argue that demand will keep exceeding supply in 2014. This might help explain why tin has performed better than other industrial metals during the past few years.
Regardless of supply and demand fundamentals, tin, like any industrial metal, peaked in 2011 as key drivers pushed industrial metals down.
Since the beginning of 2012, tin has been trading sideways (fluctuating up and down in horizontal direction). Since tin is trending nowhere in particular, it is hard to tell where prices will head in 2014.
