Tesla is getting dangerously distracted

The risk of overconfidence for Tesla is now at its highest point since the company was founded.

The business news cycle for weeks has been dominated by the carmaker's surging market cap, which at about $48 billion has passed both Fiat Chrysler Automobiles and Ford. For a brief period, Tesla also climbed above General Motors to become the largest US automaker by stock valuation.

As I've pointed out a few times, Tesla's $300-plus share price isn't driven by any meaningful fundamentals. It's pure futurism, and anyone buying in now is betting on a very big payday far down the road for Musk and his vision. In the short term, Tesla's traditional volatility will undoubtedly reappear, so the question isn't whether Tesla's stock will fall, but how far.

The company itself didn't ask for a fat market cap or to be counted among what observers are now calling the "Big Four" US automakers. Rather, Musk and his team have simply been plugging away on the fairly unglamorous specifics of execution. The company continues to increase production and sales of the Model S sedan and the Model X SUV, but more importantly, it's gearing up for the launch of the Model 3, which is slated for the end of this year.

If Tesla has a major challenge to confront when its comes to the "real" — as opposed to financially speculative — aspect its business, it's that it has so far shown itself to be pretty bad at carmaking basics. With the high-tech, high-price-tag Model S and X, this could be forgiven. But with the Model 3, the market isn't going to be so lenient. If Tesla hopes to sell 500,000 vehicles in 2018, it needs to get its assembly lines in order and come up to speed with the rest of the auto industry.

The loss of laser focus

For much of late 2016 and early 2017, Tesla seemed to be laser-focused on this mission. The public has already seen the Model 3 — it was unveiled in March of 2016 — and Musk and his team has lately been pointing out that the vehicle will be a logically "lesser" Tesla, crafted from steel rather than aluminum, with far fewer goodies than the company's more upmarket offerings.

This all makes perfect sense. Nobody should expect a $100,000 Model S if they're buying a $35,000 Model 3.

But on Thursday, Tesla lost focus, at a very bad time to do so.

I'm talking about the semi-truck announcement, which Musk made (naturally) via Twitter, his preferred product-announcement channel.

The semi is part of his "Master Plan, Part Deux," which he composed last year. It's an ambitious manifesto, taking Tesla from being a low-volume luxury electric-car manufacturer to being — as far as its transportation business goes — a purveyor of semis and pickup trucks and the overseer of a near-total rethinking of how vehicles are manufactured.
