While short sales can be an important market mechanic to send signals to protect investors from corrupt or inept corporate leadership, hidden short sales and hidden synthetic short sales work against a free and fair marketplace. If institutional and "big money" investors detect reasons to believe that the future success of a company is unlikely, hiding their short positions at best circumvents the reasoning for short sales in a free and fair market, and at worst encourages bad actors to commit price manipulation at the expense of individual retail investors.

To whom it may concern: I have grave concerns that the goals of the 21-19 rule change have too many loopholes and will not meet the stated goals of the effort. In fact, FINRA's minimal efforts at preventing ongoing FTD violations and options and swaps manipulation that circumvents REG SHO and T+2 requirements has led me to believe that FINRA is unable to be trusted as a Self-regulating Organization, and I will be informing my Congressional delegates of that opinion and strongly urging a return to direct government oversight.

The ways in which hedgefunds, family offices, and institutions are able to hide their naked short positions, whereby effecting an inaccurate short interest %, means that this isn't a level playing field. Force them to disclose ALL positions so that I, a retail investor, may choose to invest my money in a responsible way.

There needs to be a far stronger watch on naked short selling that is clearly a major issue in the current market. Investors should have full transparency to what's going on within the markets they invest their money in. The entire world has their eyes on the US Financial system at the moment. The result of the lack of oversight and control has put extreme distrust in the American financial system. The actions of major key players such as Citadel, Point 72, and many others involved in these aggressive and harmful trading tactics are a massive embarrassment to the United States.

Please help us retail investors by creating more transparency in the market! This blatant manipulation is going to cause such a dip in our reputation around the world! Limit dark pools, drop t+1 or 2, make it finally fair! You have an amazing chance to help create the best generation of investors ever!

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 direly needed change. The US market is in dire straights due to FINRA's inability to adequately police short interest. There are still gaps, however. It is ESSENTIAL for the restoration of both the stability of the US markets and the confidence of the investors within it that ANY and ALL regulation changes regarding short interest reporting be effective in EVERY known circumstance where effective short positions, synthetic or not, can go unaccounted for for ANY length of time greater than any other short position reporting deadline.
