As an European investor I'm seriously concerned about the undeniable illegal practices surrounding the US stock market and the lack of transparency. Any and all data regarding short sales should be publicly available for everyone in real time to create a truly fair and free market for retail investors.

FINRA should provide daily updates on short interest and failure-to-delivers. If that isn't feasible, then at minimum a T+1 timeframe should be implemented. Rampant naked shorting along with a financial toolbox that favors large institutions goes against what a free market is all about. As a retail Investor, I do not have the same means or access to the types of information that larger institutions do, which allows them to make better informed decisions and in effect, keep someone like myself from being able to make informed and profitable moves in the market.

Stop short sales and naked short sales, If a company holds the opposite position. If the company has a half a billion in puts and half a billion in calls, it's a SCAM! STOP THE LOOPHOLES THAT ALLOWS COMPANIES, LIKE CITADEL, TO ENDLESSLY LEND THE SAME SHARES AND SELL THE SAME SHARES WITHOUT DELIVERING THE MONEY! IT IS THEFT! RETROACTIVELY HOLD THEM RESPONSIBLE!!

To whom it may concern, I am writing in support of the proposed changes applied in Reg. Notice 21-19. Particularly as an individual investor in the US financial markets, I am strongly in support of daily aggregation of short interest reporting. I strongly support increased granularity to the account level position reporting. I am adamantly in support of increasing comprehensive synthetic short interest reporting (I would suggest a clause for these tactics to be continually evaluated and updated for, i.e.

We need daily reports on short positions to have a free and fair market.

Having been a retail investor for over two decades, I only recently discovered the extent of market manipulation really going on behind the scenes. I applaud your organization's proposed changes. Specifically I believe the markets would benefit from public dissemination, in real time, the short positions, dark pool flow, and FTD's.

Daily reporting for short sales. Fails to deliver result in 150% fine paid to the purchaser of stock that was failed to deliver.

Why are “meme stocks” being allowed to be shorted when there are no shares to short?

Institutions should be punished up to over 100% of their order amount and lose license to trade for naked short selling Institutions should not be able to hide their short positions using covered calls Short positions should be reported everyday
