Not sure we'll see a stampede of shorts exiting. I read someplace credible yesterday that short positions in TSLA have already declined from ~30% of float to ~21% of float. If accurate, that's only resulted in the stock being ~at the convert price on the March 2019 debt ($360).
Not to mention, as shorts cover and the price rises, presumably new shorts show up at least to some degree, as the new higher stock price strikes the new shorts as untenable.
That said, I expect the price of TSLA to be materially higher than $360 by 3/29, for a blend of positive reasons: Q4 earnings and cash flow/liquidity reporting, Q4 production and sales volume and Q1 order backlog discussion, Model Y reveal and deposit-taking, removal of March 2019 convertible debt potential cash call / liquidity adverse impact risk.
I am hopeful to find some down days in TSLA stock before then, so I can add to my position at least for the short run. Still aiming to pay for my Model 3 entirely with TSLA gains (1/3 of the way there so far).
