As is often the case with Musk, the timing is perfect... to further undermine investor confidence. Tesla has just posted a second consecutive quarter of declining deliveries, caught between fierce Chinese competition and a range of vehicles that is starting to smell of mothballs. But clearly, the boss prefers to play the dissident against Donald Trump, who swore by him not so long ago.

A bumpy ride...

Trump's response was swift: a mocking tweet, a threat to cut aid, and a thinly veiled question about conflicts of interest, which is comical to say the least. Tesla's stock chart looks like a snake on amphetamines. The stock has lost more than 20% since January 1, although it has recovered nearly 50% from its April lows.

Musk likes to remind us that he "thinks differently." We're starting to wonder if he's still thinking about Tesla at all... and so are his shareholders.
