Haven't seen this analyst note from yesterday reported here:
'Baird analyst, Ben Kallo, reiterated an Outperform rating and $355 price target on Tesla (TSLA) noting he would be a buyer ahead of earnings on the expectation of sequential margin improvement.'
'The analyst stated "we think results could surprise to the upside (there is an outside shot the company achieves GAAP profitability, in our view), though there are several variables, including leasing and Service/Energy margins, which could hinder near-term profitability. 2019 volume guidance will likely also be a focus as the market looks to bridge Q4; we think tightening guidance lower would remove an overhang on the stock".
His expectation of GAAP profitability looks overly optimistic in light of the financial modeling TMC thread that expects around -$200m GAAP loss with all other things equal (which they rarely are).
Regarding guidance: with 2019 deliveries guidance of 360k-400k, the Q4 guidance that is remaining after 255,200 deliveries in the first three quarters so far is 104,800-144,800 - a broad range, with the lower range being hit most likely.
That Tesla would tighten Q4 guidance in their Q3 earnings report or conference call, to around 360k-370k looks possible at this stage - or they might say that hitting the lower end is the more probable outcome at this point.
