I actually think the DB note is fair ... Till Model X comes out
I think that DB went uber-conservative with ASPs in order to get to their PT. My quick math based on their data leads to PT of $346.
So I do not think that their note is fair, even before the MX configurator goes live.
On another hand, I agree that we needed a breather...
In 2020:
100K Model S/X @ average selling price of $100K, 15% net margin à 100x100x0.15=$1,500M
400K Model III @ ASP of $50K, 10% net margin à 50x400x0.10=$2,000M
Stationary storage: 15Gwh at $250/kWh (official company pricing), 10% net margin à15x250x0.1=$375M
Total 2020 profit: $3,875
At 20x$3,875=$77,500M
Discounted 4 years back to 2016 (to reflect the 12-month PT): $52,000 / 1.12[SUP]4[/SUP]=$49,253
Assume 3% annual dilution over 4 years: $49,253 / 1.03[SUP]4[/SUP]= $43,760M
Current capitalization: $35,400 (@ SP of $279.72)
12-month PT: $279.72 x $43,760 / $35,400
=$346
------------- Edit ------------------
On an up-side to the data used by DB, I think that stationary storage will be multiples of 15Gwh assumed by DB, the auto production might hit 700K by 2020, and at that time, since there will be more factories (both automotive and battery) being constructed, the 20 PE might be unrealistically low.
