Outside of perhaps daytraders, real long term shorts are not covering based on this ER. If anything, they will be emboldened - the actual numbers were much worse than expected, all the good news was guidance, which Tesla has failed to meet 2 years in a row. Talk of cash flow positive was sketchy, since they are using new metrics to measure this that may not represent real free cash flow. Bulls will view this as new accounting measurements used by a new CFO that better represent the state of the business, bears will view it as financial engineering at best and deliberate deception at worst.
So no, if you had a bear thesis for the past 2 years, there is nothing in this ER to make you cover. However, the guidance was also good enough to give bulls ammo as well. And whether or not it is FCF or some made up cash flow, the bottom line is that they stated they will not need to raise outside capital for 2016 - which was the major fear in this current environment.
At the end of the day the question is do you believe in Tesla words or not? Do you believe they won't need to raise capital this year? Do you believe they will deliver 80-90k?
Well, if you are a Tesla long it is because you believe in Tesla, and if you are a Tesla short you never believed them in the first place. So nothing in the ER changes any of that.
As for the bottom, for me, it depends on how price action closes this week. We need to close above 160 on Friday to confirm a reversal on the weekly charts. Otherwise, expect more back and forth. Like I said last night, what got me back long is that IMO worst case <120, <100 is off the table. Not that we have necessarily hit bottom.
