Suggestion - many traders like the ability to designate which block of stock they are selling to avoid the default IRS FIFO rule. I've seen, but forget where, some online brokers have a pull down menu. Others require you to call and speak to a broker, resulting in a higher commission. I know Ameritrade allows you to email a request to designate after the fact. I find the latter a big waste of time and would find the first approach attractive.
