The NMS is under threat.

There are overleveraged MMs that are engaging in naked short selling, intentionally. This is creating millions and millions of \"synthetic\" shares in several securities in the NMS including 10-year Treasury bond.

They are hiding their FTDs by resetting Reg SHO close-out obligations via deep ITM call options that have little to no open interest.

This blatant market manipulation has put the whole economy in jeopardy.

SR-NSCC-2021-801 needs to pass in order to better regulate these MMs that are engaging in \"grey-area\" activities.
