You'll be charged a transaction fee on each stock you need to sell. It really depends on what type of account you have. Also, if you do it over the internet, it usually costs less, than calling someone, or walking into an office and making the transaction. An internet trade (with my brokerage firm) is usually $25 per stock, up to 1000 shares, after that, the fee goes up. I believe a phone transaction is around $50, and a person assisted transaction (placed in an office) is $100. Now, this is per stock, since each is considered a separate transaction.
