Context
This was an option exercise (transaction code M) with tax/exercise withholding (code F), commonly a routine corporate liquidity/tax event rather than a sale reflecting market sentiment. The filing indicates a net (cashless) exercise — shares were withheld by the company to cover costs and taxes, not sold on the open market.
