Context
These were sales — including tax-withholding sales tied to RSU vesting — which are common and do not necessarily signal a change in executive confidence. For retail investors, purchases by insiders often convey clearer bullish signals; this filing documents routine liquidity/tax-related sales rather than an acquisition or exercise-based change in ownership.
