You are totally wrong about a cash dividend of any size. Short sellers can easily come up with any amount of cash. (in-lieu-of payment). They can't come up with shares that don't exist.
From my point of view Frank and I started out with an open mind., my position shifted because thinking logically through everything we knew, there was no strong evidence for the impact of the dividend split on naked shorts, and even less solid evidence for a large pile of naked shorts.
Still not enough IMO to rule the theory out entirely, but not enough to rule it in.
A cash dividend as 2 effects:-
1) Short-sellers of all types need to come up with the money.
2) It puts upward pressure on the stock price via the following mechanisms:-
a) New buyers are attracted to the stock.
b) Existing shareholders can use the dividend to buy more Tesla products, or reinvest the dividend in more Tesla shares.
c) Large share-holders like Elon. no longer need to sell shares to finance a number of activities.
d) Many short sellers are highly likely to head for the exit.
1) Makes short sellers of all types want to close, 2) makes it very hard to close without a loss.
My point in context was accumulating a large naked short position is Tesla, is financial suicide. It is very high risk for low reward, so no one sensible would do it willingly. That is one reason why I doubt a large naked short position exists.
Obviously if we get strong evidence in any area, I'll change my opinion, and I expect Frank will change his opinion.
But overall this subject has been beaten to death, we can agree to disagree, in a well mannered way.
