@Artful Dodger Does your microeconomics model have an estimate for the current amount of naked shorts?
We can make indirect estimates based on share volume and price movement, but there are caveats.
The main one is that the existance of HFT skews our measures of volume (where the same 1 share bounces btwn 2 hedgie's servers at high speed 10M times but for an net trade of zero). This distorts the volume reported so that we never see the true exchange of shares, making it difficult to apply a micro-economics model.
However, we are able to use special events like the S&P 500 addition on Dec 18, 2020 to estimate the total volume of shares that MUST be transferred to new beneficial owners. This is a case where the signal-to-noise ratio from HFT allows us to extract statistically significant estimates.
The S&P 500 addition lead to the sale of about 80M shares in the event, and my Dec 14, 2020 model prediction (published over in the Main thread) was accurate to within just a few dollars of the TSLA equilibrium SP on Mon Dec 21, 2020. That was a good validation of the model.
However, there was a 2nd shoe that dropped. We didn't get the new SI information for Jan 31, 2020 until after the Close on Jan 12, 2021. That's when we saw the true extent of how much net shorting occurred while providing the ~120M shares that traded during the Closing Cross on Fri, Dec 18, 2020 and during the AFter-hrs session. Turns out, about HALF all all those shares were sold short, but (again) we didn't find out until Jan 12 when we saw the net change in SI.
This newly updated SI data did predict the $880 equilibrium SP which would be required to lead to the sale of that volume of shares (based on historical data for elasticity of demand for TSLA).
Sadly as we know, the shortzes then just resumed their gambit and attacked the stock again the day before Q4 Earnings were released on Jan 26, 2021 (orchestrated by big shortz M. Burry).
The rest is statistics. We'll have a way of estimating what happened in December, by the middle of January, I'd reckon.
TL;dr HODL'ing
Cheers!
