Equity Markets Specialist

Sales were small relative to total holdings but are material as disclosed insider activity.

The combined sale of 2,706 shares represents a de minimis percentage of the reported post-transaction holdings (~0.26% of the reported million-plus stake), indicating these were minor dispositions rather than large divestitures. Prices reported were $3.5167 and $3.4633.
