Re: the last transaction, what if I sell someone a couple shares of Microsoft stock for $1? That obviously wouldn&#x27;t affect the stock. Is there some mathematical expression of amount of stock that has to be sold to impact the price? Or is it a question of the sale being done by certain authorized entities?<p>BTW, if you don&#x27;t see &quot;reply&quot; under this comment like I don&#x27;t for yours, you can go to my profile page and &quot;comments&quot; and then you will see the &quot;reply&quot; link.
