Position Trader

A position trader is someone who holds a position, usually stocks, for the long term; from weeks to months, even years. They are less concerned with short-term fluctuations and the news of the day unless it impacts the big picture behind the stock they are trading. Position traders do not trade actively and the fewer trades they make in a year, the closer they are to becoming buy-and-hold long-term investors.
