1/ Now that short interest for $TSLA is out encompassing the latest "miracle quarter," Goober was quick to point out the impact of short covering. Of course, Goobs is mistaken.
2/ Tezzler short interest now stands at 31.8mm shares, approximately where it was on 3/29/19 when the stock was at $279/share. Here's the data. There have been periods in the last 9 mos where SI decreased and the stock went down, and also the opposite. 
3/ While it is tempting to become Goober, look at the data and say: "of course short selling drove the stock down, look at the prices in March and April, so of course short covering pushed it back up."
4/ Now look at the data with an assist.
1/23/19 Headline: "Tesla's Mass Layoffs and Reduced Car Production. . .Wall Street waking up from the Dream."
2/28/19: Musk Claims Tezzler Will Not Be Profitable.
4/3/19: Tezzler kills it on deliveries. Oh, wait. . .

5/ The headlines came first, which attracted momentum short selling. The headlines knocked the stock down, then the short selling came in. But, whatever short selling came in was dwarfed by long sales and dealers scrambling for cover.
6/ This stock trades like water, days to cover has always been way low. And, short interest has been much lower in the past, so I doubt a 5mm change in short shares triggered a 40% rise.
This has always been a headline stock. Always will be.

Musk likes having a restricted float and an ignorant shareholder base. It enables him to pump with effect. In April/May, headlines were driving this down, not a 10mm share increase from shorts. 10mm shares sometimes is a day's trading.
