Love that phrase. Why car metals? The two below are used to make car parts.
Both platinum and palladium ETFs are not trading (PPLT and PALL, respectively) and after some hefty run-up, both underlying metals look ready to fall. This happens every time a new ETF comes out.
Take your pick - money coming out of these goes into gold and silver to stay in metals or these two drag all metals down with them. I favor the former.
