If you sell a stock does someone really buy it or have to buy it? Does the market buy it? Reason I ask is that I sold 20k shares of a tech stock yesterday because I had a bad feeling about it. Looking at the market report I can see where my shares traded but about an hour later the stock stumbled quite a bit. Just wondered if the shares sell instantly or do they dribble out if no one is interested. BTW I came out ahead.
