My guess for the price decline is that it is more a reality check on the unjustified hype that has been so common lately.  Speculation swings both ways... in this case Up.. then Down  Of course, should the Tesla "deal" actually materialize then that same swing will rapidly go back Up.  As has been stated over and over again, we need to see concrete Milestone achievement for LAC in order to see a secure rise in Share Price that won't suffer from the Yo Yo effect.  It will come... once the Milestones are achieved, but this Pumping speculation that has been so rampant is only good news for the day traders and it undermines the hopes of the longs... temporarily, until those true Milestones are achieved.   JMO, of course
