This rule change is long overdue for the sustainability and transparency of the markets.

If a security is sold, FINRA should have a record of it whether it is generated from. I see your folks are focusing on synthetic, fake shares generated to "provide liquidity" via options but security-based swaps, mismarked longs and any other financial instrument institutions may use to sell a share they do not have NEEDS to be reported to FINRA. When you folks have this information you cannot allow banks, market makers and other financial institutions to "provide liquidity" when there is no liquidity to be provided.

The reporting of shorts and especially synthetic shorts have been overlooked for a very long time, because of this I absolutely believe this will benefit every single investor. These rules should be implemented and require daily reporting to the public by the firms FINRA regulates. I sincerely hope that FINRA implements and enforces these rules as the confidence in the state of todays stock market is extremely lacking due to the inaction by the regulatory bodies to enforce the rules they themselves set.

FINRA 21-19 is a regulatory change we must incorporate and enforce in our markets. It is clear to me as a retail investor that the integrity of the US market has been strained, and personally I have lost almost all faith in it. This sentiment stems from the regulatory and enforcement failure in large part due to systemic risk developed under the regulatory authority of FINRA's outdated short interest reporting policy.

Please implement this type of fair regulation for reporting requirements. The current standard is almost promoting the misrepresentation and manipulation. I have lost faith in Finra and the SEC. Do more to protect the people not just the big funds and people with all the access, power and money. Thank you

Every share should be tracked with unique identifier. Every share should be located and lent once only. Every order should be delivered T+2 or fails mean 10x cost penalty. Every short position should be updated with FINRA daily.

FINRA 21-19 is a long overdue change. It is clear that the integrity of the United States market has been strained to the edge of disaster, in large part due to systemic risk developed under the regulatory authority of FINRA's outdated short interest reporting policy. While many of the policies mentioned in Regulatory Notice 21-19 address the general breadth of exploitable and ineffective reporting, they also leave significant specific gaps that could compromise the entirety of 21-19's purpose.

FINRA 21-19 is a long overdue change. It is clear that there is a systematic flaw in the United States market that if continued, will lead to disaster. A large part of this issue is the outdated short interest reporting policy.

Retail Investors in the U.S and around the world are becoming more aware of how the financial industry works. Regulatory notice 21-19 is critical restoration of trust/confidence and stability in the U.S. markets. All regulation changes regarding SI be effective immediately in all circumstance: short position, synthetic or otherwise. The cost of operations needed for applicable market members to accommodate these standards versus a compromised market with systemic risk and or loss of investor confidence and participation are night and day apart More transparency!
