يبدو أن تقرير دعوى التمثيل الأخيرة لشركة RobinHood قد أثبت بيانات /u/broccaaa. أن المُستَقِرَّين لم يغطوا مخاطرهم، وأنهم خفوا نسبة SI من خلال خيارات شراء مُستفادة بعمق، وأن نسبة SI تبلغ على الأقل 226.42%.

Possible DD 👨‍🔬

Edit: Numbers from RobinHood case are alleged so far, not proven. I cannot edit the post title. That being said, results of Deep ITM CALLs comes up with roughly the same 226.42%, which is quite telling. We also see that PHLX exchange is used to buy and exercise these calls almost immediately - exactly as outlined in the SEC document on how to shift a short position to become synthetic. 0. Preface

I am not a financial advisor and I do not provide financial advice. Thoughts here are my opinion, and others are speculative. Shout out to king /u/broccaaa for their contributions. I always figured that your assumptions were correct that the SHFs were using these Deep ITM CALLs to hide SI%, but we never got some quick maths behind it to see if it was true. (Maybe we did though! Sorry if I did not see anyone's posts about this) Well, this is for you /u/broccaaa, and all the apes.

Spreading Love To All

Way way back in time, since many of you probably feel like you've aged years over the course of 6 months, there was a blip of 226.42% SI in January. Many believed this was a glitch:

That's what many may have thought, that it was just a glitch, until recently a Class Action against RobinHood proved that was, indeed, the SI% upon January 15th, 2021: Edit: Thank you much for everyone's replies. We must consider this as still speculative and not proven as it is a number alleged by the plantiff. Allegedly, per a Class Action against RobinHood, the SI% was 226.42% upon January 15th, 2021:

Put yourself in the SHF's shoes. You have a shitload of retail buy pressure going on. You're way overshorted. What do you do? Do you cover? Pfft. Nah. That's way too much. Impossible to cover. Absolutely screwed. Lucky for you the SEC has identified malicious options practices which can be used for just such an occasion to make it appear that you've covered. Let's say you want to make it "appear" that you covered your short. You can perform a buy-write trade with a bona-fide Market Maker. Who might help you out as a bona-fide Market Maker? Citadel might come to mind (not saying it's them, just an example since they are well known)! The trade ends up being the following: 1. Trader A who needs to hide their short position enters the buy-write trade with Trader B (Citadel). 2. Trader A sells a Deep ITM CALL to Trader B (Citadel). 3. Trader A simultaneously buys shares from Trader B (Citadel). 4. Trader A now appears to have purchased shares to cover their short position, and Trader B (Citadel) gets a small amount of cash in return.

• 	They tend to trade Deep ITM CALLs that have little to no OI so that the trade is almost

guaranteed to be between Trader A and Trader B.

• 	Trader B tends to exercise these CALLs on the same day. And this is exactly what we 

have been seeing because CALL OI does not increase.

• 	The net effect on this is that Trader B has looped around their shares. They sold them to

Trader A, and then got them back through exercising the CALL. Meanwhile, Trader A has "covered" their original short position but now they are "short" the CALL, meaning it is now a synthetic short. Here is the supporting text from the SEC itself if you want to verify for yourself. A report from 2013 titled "Strengthening Practices for Preventing and Detecting Illegal Options Trading Used to Reset Reg SHO Close-out Obligations":

So, they can utilize Deep ITM CALLs to hide their short positions. We don't care about identifying Trader A and Trader B in this case. Just the fact that trades occurred on these Deep ITM CALL strikes and that OI is unaffected the day thereafter. That's enough to support the above theory that they're utilizing this practice to make it 'appear' that they've covered their short position. Check out what /u/broccaaa's data identified. Tons and tons of Deep ITM CALLs were traded in January prior to SI% dropping off of a cliff. By my estimations, about 1,100,000 CALL OI was traded prior to January 29th SI Report Date:

The SI Report Date of January 29th matters because that is the cutoff of when FINRA will require settlement of short interest numbers for the next SI report date. The next SI report date following January 29th settlement is February 12th. And we can see that after the mayhem of Deep ITM CALL purchases, SI% dropped from 226.42% of the January 15th report, to 30.2% upon February 12th:

With the difference in SI% from 226.42% on January 15th down to 30.2% on February 12th, we can assume that they have not covered their short position but rather hid their short position in synthetics if we can come up with a roughly equivalent SI% from the approximate Deep ITM CALL purchases. The float of GME in January was approximately 57,840,000. The estimated Deep ITM CALL OI that was swapped is ~1,100,000 OI = ~110,000,000 shares worth. Which then gives an estimated SI% reduction of ~110,000,000 / 57,840,000 = ~190.18% shorts hidden between January 15th and February 12th report date. And since SI% on February 12th was 30.2%, then that gives a grand total of 190.18% + 30.2% = 220.38% SI per estimations. That's dangerously close to the reported 226.42% SI from January 15th. So with that in mind - do you think they covered?
