Kevin,
I plan on modelling Tesla's Q2 earnings before Aug. 7 and updating the board on what my exact expectations are. In the mean time my posts are scattered all over the board about what to expect from Tesla in Q2. I have also written a lot about solar energy, because that is the one industry that I think will have huge returns in the very near future.
Going back to Tesla, they have more car sales and significantly better margins going in their favor vs. Q1. The downside is increased SG&A and possibly lower ZEV credits (and no warrantly liability gain). I think the upside significantly outweighs the negatives, hence my $0.20 EPS number at a minimum. Their are other unknown items such as forex, tax rate, car mix (40 kWh & 60 kWh most likely offset by Performance Plus), development revenue (risk is to the upside IMO).
I think that if Tesla plays their cards right with guidance ($1 EPS for 2013, 24,000 cars delivered) then the stock could hit $200. Of course, I might be missing some significant expenditures in my estimates, but I cannot think of any that may have slipped (capex is amortized over many, many years).
I cannot envision a scenario where Tesla has negative earnings unless ZEV credits go down by 50%+ and everything else works against them, i.e. forex, taxes, etc.
