A short squeeze might or might not realize in 2019 (Q3 is a significant hurdle), but it's
highly misleading to calculate short covering capacity of the market by using the daily volume:
- Firstly, there's been several short squeezes already: last June and last October were examples of ~50% up-moves in TSLA, in significant part fueled by short covering. So to claim that Tesla short squeezes are a myth is simply false.
- 80% of the daily volume is bots trading with bots, trying to front-run and to pick pennies. The overwhelming majority of HFT and algorithmic trading entities go flat at the end of the day, i.e. they close whatever short or long positions they have opened. They have no effect on net long or short positions and offer no real liquidity for shorts to use to cover.
- Long-term trading volume is 11 million shares per day according to Yahoo Finance (TSLA). While there are 15m+ days, there are also ~7m shares traded days - the average is 11 million shares per day. The 20% "true liquidity" of that is only 2.2 million shares of net accumulation/distribution power, on average.
- If all of those shares are investors selling to shorts so that they can cover, then it takes about 20 trading days or about 1 calendar month to cover the 46 million shares sold short.
- But during any short squeeze covering shorts will have to compete for liquidity with new investors who are seeing the up-move and the improvement in sentiment - both opportunistic short-term ones and long-term investors. Every failed short thesis is an investor's promising bull thesis. Existing longs will also upgrade their price/profit expectations and will not sell at price levels favorable to shorts.
- If we assume that new investors compete with covering shorts on a 50%/50% basis then during the up-leg of a short squeeze liquidity becomes even thinner: only 1 million shares a day - 46 trading days and over 2 calendar months. This only stops once the up-move reaches price levels that many investors equate with an overheated price. Even today TSLA is far away from such price levels.
- But it gets even worse: the "Summer doldrums" in U.S. markets usually mark an about seasonal 15%-20% drop in liquidity. So if a short squeeze started today, they'd have even less liquidity to cover.
I.e. in practice the TSLA short trade is
way overcrowded, and it will be largely bulls/longs who determine the price levels and timing when most of the 46 million shares short will be allowed out of their short positions: them trying to do it only drives up the price. Only longs have the shares they need to cover in any significant quantity.
A recently leaked analysis from Morgan Stanley estimated that around 75% of the selling below $200 levels came from short sellers. Such selling pressure is simply not sustainable, and the TSLA borrowing rate is increasing already.
Around 50% of the short position came in at price levels below $300. Should TSLA reach $300 again all those profits and the trading power will evaporate. I'd say shorts will be significantly weakened in their ability to control the TSLA price at $250 already.
I'd agree that a 2008 VW style "fast" short squeeze is unlikely, but if Tesla posts robust results and the macro sentiment doesn't deteriorate then a 1999 Qualcomm style or a 2013 Tesla style "slow" short squeeze is in play I think.
As
@neroden said it recently: a short squeeze will eventually happen, but at a time when we are the least expecting it.
