COSM
Cosmos Holdings Inc. Common Stock
stock NASDAQ

You're doing exactly what I asked people to do at the bottom of every post: *verify it.*
You've caught real errors today. The COSM split ratio was wrong (1-for-75 → 1-for-25). The "synthetic shares" framing was an overreach, the proximate cause was a processing error, and I've rewritten Section 4 to reflect that. The RECAPS mechanism was imprecise for a CNS-eligible security, your A#6848 citation forced me to rethink the entire transmission mechanism, and the section is now significantly more precise than what I originally published.
I'm a solo researcher. I don't have a peer review board. People like you *are* the peer review. Every correction you've posted today made the analysis tighter. I'd rather be publicly corrected and publish something accurate than protect my ego and leave errors in the record.
If you want to keep going through the other sections, I'm here for it. The series is meant to be pressure-tested. That's the point of open-sourcing the data in the GitHub repo, so people who actually understand settlement mechanics can check the work.
Thank you.

You're right about the proximate cause, Robinhood failed to adjust customer share counts for COSM's 1-for-25 reverse split (I had the ratio wrong at 1-for-75, will correct). The post overstated the mechanism. I'll update the language.
But I disagree that this has "nothing to do with synthetic shares." Robinhood's own CFO said it on the earnings call: *"A processing error caused us to sell shares short into the market."* The X-17A-5 says: *"Customers sold shares they did not own, creating unauthorized short positions."* Those are Robinhood's words, not mine.
The question is: why did a simple reverse-split divisor error result in $57 million in market-moving short sales before anyone noticed? In a system where the broker's internal ledger reconciles with the DTC's position record in real-time, a split adjustment error would be caught *before* any trades execute, the share counts wouldn't match. The fact that customers were able to sell phantom shares *into the open market* means Robinhood's system allowed orders to execute against share positions that didn't exist at the DTC level. That's not just a math error, it's an architecture that permits selling shares that aren't there.
The forensic value of COSM isn't that it proves synthetic GME shares. It's that it proves Robinhood's settlement architecture *can and does* allow customers to sell shares they don't own, and that the system doesn't reconcile against the DTC position before executing sell orders. That has implications beyond one micro-cap stock.
I'll update Section 4 to correct the split ratio and tighten the language around "processing error vs. synthetic shares." Fair pushback.

Comments on section 4 "The Ledger Leak".
The issue was not synthetic shares. The problem is that COSM announced on Dec 15 2022 a 1 to 25. (Not 1 to 75) reverse split, just hours before the market opened on Dec 16.
Robinhood did not adjust the sharecounts in customer accounts, so they showed 25 times more shares than they should have had. Many RH customers sold. Since the number of shares had not been adjusted for the reverse split, they were able to sell many more shares than they actually had.
It had nothing to do with synthetic shares. It was simply that RH did not divide each customer's sharecount by 25 like they should have.
