I like your humour.

TSLA stock fluctuations really keep me on my toes. -10% on one day, +10% on the other. It is an emotionally charged stock.

you mean like Autopilot https://www.cnbc.com/2018/01/31/apples-steve-wozniak-doesnt-...

"Man you have got to be ready — it makes mistakes, it loses track of the lane lines. You have to be on your toes all the time," says Wozniak.

I don’t think Woz should be seen as a particularly relecant commentator on Tesla (Tim Cook, despite not being an Apple co-founder, would be far more interesting). But as usual, I find myself nodding in agreement with Woz’s worldview.

... why not relevant commentator? He's got the geek cred.

Not necessarily about cred, but because he's not in an industry position or otherwise has the insight that Apple "co-founder" suggests. Don't get me wrong, I think he's was as vital to Apple as Steve Jobs was in its pre-iPod era.

High volatility makes it a day trader's dream stock. It most closely approximates one of the older dot.com stocks.

Volatility is your friend.

It literally bought me a boat this week.

I picked up some at the money May calls Monday. I sold them today, and (mostly coincidentally) bought a sailboat. The options, after taxes, covered the boat and this year's moorage.

Could've gone the other way of course, but after the beating they'd taken? Surely they'd do something to correct between Monday and earnings.

They said, I might amend your statement to be emotional volatility is your friend. I mostly got lucky on the response to Tesla coming closer to meeting their production goals (entirely independently of the underlying financials). It elicited a predictable emotional response.
