Tesla's best hope and its worst enemy are the same thing: Elon Musk. While he is a great visionary that Tesla very much needs to keep driving it forward, he is quite possibly one of the worst managers judging by the trajectory Tesla has been on the last year. The best thing for Tesla and its stock, long term, would be to bring on board someone who can take over daily management responsibilities in a (drum roll) responsible manner. All of Model X's issues can be directly traced back to Musk. The fact that Tesla still can't figure out how to make this car in volumes approaching the S is alarming at best.
Of course earnings are going to disappoint. When haven't they? Today's stock price is 100% related to the false hopes and expectations raised by Tesla's CEO only to downwardly revise some of those expectations later in the year. We call that eating crow. Yet he continues to repeat the pattern. He can't help himself. At the same time, the car's core software systems are stagnating while new competition is queuing up (Bolt).
Now Tesla is accelerating towards Model 3 production when it hasn't even figured out Model X production. Tesla is suing one of its former suppliers over failing to properly design the falcon wing doors. Sounds like sour grapes to me, passing the buck and blaming the vendor for what is just a poorly thought out design. But that's nothing new to Tesla. Elon demoted Jerome Guillen over poor performance in China, eventually leading to Guillen's leaving the company. Yet the decision to enter China in a spectacularly bad fashion was Musk's. Same with Hong Kong where hi pissed off an entire country full of Model S owners by not even bothering to follow the law in HK with regards to failing to obtain regulatory approval for Autopilot. At one point Musk called his own employees in China "morons" or something to that effect.
Amateur hour is over. We need a real leader to take over the day-to-day management duties from the engineer who has an obvious problem managing both priorities and expectations. Tesla lost George Blankenship, Jerome Guillen, and Deepak Ahuja. Judging by the state of Tesla's executive management page, it doesn't appear there is anyone left. Tesla is pissing off too many people, most of them owners, and I believe Tesla's downward spiral may have begun.
