Members must apply a 100 percent margin rate on all open positions as of August 20, 2026. This margin rate also applies to new positions created from August 21, 2026. Securities that meet the criteria for Stage IV shift from the Rolling Settlement segment to the Trade-for-Trade segment effective August 21, 2026. These measures operate alongside other existing surveillance actions. The inclusion of securities under this framework results from market surveillance and does not represent an adverse action against the affected entities.

- Apply a 100 percent margin rate on new positions created from August 21, 2026.
