I'm sure that the supplier issues have factored into the sell-off, but I've seen very little discussion of that. I saw one piece on market watch and a handful (maybe 5?) tweets on the subject. On the other hand, talk of the non-GAAP vs GAAP profit has been everywhere. And everyone is talking about being overvalued based on expectations.
Based on the lack of discussion anywhere, I have a hard time attributing the whole move to the supply issues mentioned.
I think the non-GAAP vs. GAAP profit noise just has to do with retail traders.
I can't imagine that the fund managers at Fidelity Contrafund sit around and look what people at Stocktwits and Seeking Alpha has to say about Tesla. For that matter, I don't think they care about what Tesla has to say about Tesla and how it breaks down GAAP and non-GAAP. They're going to look at the raw numbers and come up with their own conclusions.
But, if I were a fund manager, the fact that Tesla can't get their production rate up would be of grave concern for me. Tesla now has the ultimate first mover advantage, and that's priced in. But they need to execute on it for it to be helpful. If Tesla can't get their production rate up in a year, they're going to start losing sales. The i3 may not be great, but it sure beats driving a Jetta around Europe while waiting years for your Tesla to arrive.
I cringed when I saw that Tesla HK phonecall earlier today.
If they can't get fix this in the next year, they'll start being ridiculed. All those people who said that you can't make enough batteries to support EV's will start writing "I told you so" articles.
So yes, I do think that by not increasing the guidance, and by saying it won't be fixed for at least 6 months, impacted the stock price. The stocktwitters may be off in la-la land, but the institutional money is going to see the bigger picture, and a 6 month delay to a first mover is a huge deal.
Saying "We don't have a demand problem, we have a production problem", isn't far off from saying: "We have millions of people lining up with $20 each to use the Hyperloop - we just don't know how to build it."
