Trying to understand the reasons for TSLA stock movements will drive you crazy. Just know that it goes up and down a LOT, sometimes quite rapidly. Expect that to continue for a while.
Tesla is going to go through continued growing pains as it works through the global market demand for the model 3, specifically the various trim levels. They are trying to figure that out now for the U.S. even while rolling out the higher trims globally. Production clearly now exceeds the U.S. demand for the higher trim levels. They have really just started to produce the lower trim levels (SR/SR+) for the U.S. No one actually knows the overall global demand for the model 3. Tesla has an idea but there really is no way to fully know it in advance. I don't think anyone who is being honest believes the sustainable demand ceiling globally is under 10,000 per week. However, this is a new frontier so there is uncertainty, particularly around the question of sustainable demand.
There are some signals to look toward for answers to the sustainable demand question such as: the percentage of model 3 owners who are new to Tesla, polling data that indicates the percentage of people looking to buy an electric vehicle, and the historical sales data regarding the model S. Until we find out the actual sustainable demand for the model 3, we simply can't know. This uncertainty, while real, is being fully exploited by the anti-Tesla crowd which is undoubtedly having an effect on the share price. Model S ended up having much higher demand than Tesla originally anticipated. Tesla has quite a bit of data at this point regarding global sales of the model 3. They are in the best position BY FAR of anyone to have the best idea about global demand, certainly much better than the financial analysts who are issuing all of the downgrades on the stock on the basis of concerns over sustainable demand.
