Isn't it because "Tesla, a public company, promised/projected this production goal"?
Since the eighties there has been this maximal version of shareholder value, where the only reason for a company to exist is to maximize returns to shareholders. This was promulgated by private equity firms who would take over a firm and destroy many of the good things that a company was doing that didn't generate profits in order to increase returns to shareholders. Prior to the PE hostile takeover boom, there was a general understanding that shareholders were very important, but not the only stakeholder in a corporation.
If you invest in Tesla though, don't count on the corporate raider philosophy of stock ownership. They may have been able to get other companies in line with the threat of a hostile takeover, but Tesla has protective provisions that make it nearly impossible to do a hostile takeover of Tesla. For better or worse, Tesla is whatever Elon Musk wants it to be. If you're a shareholder, you're just along for the ride.
What has really changed is how money moves in the markets and particularly the degree of short-termism being expressed by investors. That has a lot to do with the tremendous growth in available securities (related to opportunity cost), the increased efficiency of capital markets, dramatically lower transaction costs, and the general velocity of capital in the system. And of course, it’s just inherently easier to project near term than long term outlook and always will be.
If you don't like what they're doing, you are free to divest. This is a free market after all!
The general reading of the fiduciary duty to shareholders is that directors of corporations are bound to promote the value of the corporation for the benefit of the shareholders.
The primary means shareholders have to change the direction of the company is to elect a different board of directors. In the case of Tesla, that requires a 2/3 majority, and Elon holds 27% of the stock.
I agree with this. But IMO Tesla and the like are different because they're tapping into something more. People are actually excited about electric cars now, and they're willing to put money toward the goal and let Musk steer his company, taking them along for the ride.
I am not saying that they will, and I hope they will not.
But since a few weeks, I do not completely rule out the possibility anymore. Because if only some of their problems, that are being reported right now, are systemic or hard to fix, 2018 might be a bad year for Tesla...
Comparing a 80 year old company production with a 14 year old company and expecting the same production power is unrealistic.
