According to Ihor Dusaniwsky, short interest is up to 39.24M shares -- the highest it has been in a year and approaching the highest levels ever by share count (by percent of float it has been much higher, for example in late 2012/early 2013). It is also an increase of 14.5 million shares from January 31, exaggerating the downward pressure on the stock.

Historically Tesla has had a strong pattern of "short low, cover high" with peak shorting when the share price was lowest. I have documented this a few times, including in the post below from June 2017. The same pattern occurred again last year about this time. Pretty amazing.
This time could be different, of course.
