So, now that the stock price has dropped down to $305 and change, just how have the short sellers been damaged? The closing price on the day prior to the ill-fated tweet was around $300. The high price the past couple of weeks was $379 and change. Any damages will be inconsequential and difficult to prove. We are talking about a volatile stock. Let's assume Musk never touched his tweeter account. Who is to say that the stock would not have risen slowly the past two weeks and closed yesterday at $325, instead of remaining essentially unchanged. Part of this downward movement has got to be with all the press that Musk has received lately as well as the pending investigation by the SEC.
Big deal, there was a ten-day period where the shorts had to pony up additional collateral, or perhaps a few had to close out a percentage of their short positions. But today, they are essentially back where they were 18 days ago. Five bucks is immaterial, and the price could even drop further over the next 4-6 weeks given its historic volatility.
I am not a lawyer, just a bean counter. To me, this is just a grandstand play--a veiled threat--to keep the shorts in the news, to distract Tesla and Elon Musk, and to pander to the uneducated masses.
And in my ignorant viewpoint, option players on Tesla stock are not short sellers. They are only at risk as far as their premium is concerned, and options players should be acutely aware of the volatility of any option contract, especially Tesla.
