Context

• RSU vesting and conversion are administrative (compensation-related) events, not open-market purchases or sales. The "M" code here denotes exercise/conversion of a derivative (RSU) and the reported derivative "disposition" reflects cancellation/settlement of those RSUs upon conversion.
• These transactions do not involve a cash sale or purchase and therefore do not directly signal buying or selling pressure in the market.
