Open-market Operations

The most common share repurchase method in the United States is the open-market stock repurchase, representing almost 75% of all repurchases. A firm may or may not announce that it will repurchase some shares in the open market from time to time as market conditions dictate and maintains the option of deciding whether, when, and how much to repurchase. Open-market repurchases can span months or even years. There are, however, daily buy-back limits which restrict the amount of stock that can be bought over a particular time interval again ranging from months to even years.
