Bezos Wraps Up Sale Of $3.4B Worth Of Amazon Shares. 📊

Arrayfunction : Do you know how those pre-arranged plans are "priced into" the overall share price like those people who tout that wonky "perfect market efficiency" idea?

At the most superficial level, it would be as simple as adding in a price drop from the increased sell volume. But I doubt it is that simple? Perhaps the sell volume's effect on price is dampened by increased buying volume from people looking to get the shares "on sale" per that 1st level? Or shareholders may feel more confident their interest will be better prioritized if the voting becomes less concentrated in the whims of a single person? Sort of a non-financial metric of how far on the "value" scale a stock goes?
