I suspect today's action only due to lack of earth shattering news yesterday. A lot of short term plays out there in anticipation of surprise announcement but not really much new, just steady execution of the plan. So those positions liquidated.
Chickenlittle, that's a reasonable explanation. What we need now is for Panasonic to sign a gigafactory agreement with Tesla and for tentative GF sites to be named so that the permitting process can begin. Once these steps are taken we will see an advance in the stock price. My point was that with bad information out there that the GF decision would be delayed until year end, some traders may have been influenced by the bogus news. It's possible some traders may still be misinformed, and thus an announcement of GF site choices would be doubly important.
