Selling stock is procedurally similar to buying stock. Generally, the investor wants to buy low and sell high (short selling), if not in that order although a number of reasons may induce an investor to sell at a loss. As with buying a stock, there is a transaction fee for the broker’s efforts in arranging the transfer of stock from a seller to a buyer. Importantly, on selling the stock, in jurisdictions that have them, capital gains taxes will have to be paid on the additional proceeds.
