The theme of the article is interesting. It sounds from the headline like it's a positive take on Tesla, right? No, not at all. The premise is that the shorting should make sense and be a good idea if the stock behaved rationally. He is saying that Tesla longs are just such clueless idiots about finance that they are enthralled with Tesla's story and keep buying and won't let the stock go down even though Tesla is in every kind of trouble and obviously going to fail. He's just saying that shorting doesn't make sense against that kind of irrational, unfounded stock support.
"Tesla keeps upping the ante on really bad. Nothing in its history of generally awful execution has held shares down for long."
"What the shorts don't understand is that the patience of the Tesla bulls is endless, and their capacity for devising ingenious new storylines is inexhaustible. Very few companies are simply beloved, in the way that Tesla is. Shorting that kind of thing is like shorting romance or sunshine. Why bother?"
