Fundamental:
Many investors are overlooking an important aspect of tesla:
The new Tesla Roadster(0-60mph in 1.9 seconds)(620 mi eletric range), which will be realeased approximately in the first quarter of 2020, creates a auspicious offer for every adrenalin junkie that isn't content with the 4.8 seconds from 0-60mph from a Porsche 911 Carrera.
Of course we have to look for the rising procurement costs of teslas battery recourses (cobalt,lithium,nickel,graphite). If those are getting to high tesla could have a slight monetary problem.
I think the demand of the Tesla Roadster is able to compensate their procurement costs.
Technical(see update)
--> If the market is able to stay above the support line of 180$ (Of course the USA-China-trade dispute has to find a end), Musk got one more chance for his really strong Brand-value to remain.
