Definition of 'Roll Up'
The move from one option position to another that has a higher exercise price. A roll up is a trading action whereby an investor or trader closes an open option position while simultaneously opening a new option position that has a higher strike price or a different expiration, or both. A roll up is typically performed if an investor is bullish on an underlying instrument, such as a stock, and he or she believes the price will rise. This is the opposite of a "roll down" in which an investor simultaneously closes one position and opens another with a lower strike price.
