RE:Cobalt hits a new highActually, the hoarding may seem good, but might not be. Sure it raises prices now, but it could crash precipitously later. The common wisdom now is that the "dumb" buyers (hoarders) will be offset by the Chinese later, who will buy the crashing Cobalt when the hoarders dump. In fact, most think $25 is not that out of the ball park for what Co should be, and if the price keeps rising to say $50, when they dump, it will drop $20-$30, but the Chinese will buy then. So there is insulation.
Instead of Hoarders, a far better idea is to have Tesla's Model 3 production ramp up in a few months, with continued EV growth in 2017, to filll in the base for this faux-floor.
I am as weary of Hoarders just as I am any chaos in the Congo (which caused the $50/lb price hike and rush for new mines, but also the 2 year hiatus from reasonable levels as it crashed to hunder $10/lb).
Just food for thought...
