GMCR – Green Mountain Coffee Roasters, Inc. – News the specialty coffee company plans to increase the price of its single-serving coffee packs, known as K-Cups, by 10% to 15% starting October 11, 2010, fueled an 8.75% rally in the firm’s shares price to an intraday high of $33.94. Green Mountain cited mounting green coffee prices and other short-term cost increases as impetus for its decision to charge more for K-Cups. Investors expecting the coffee maker’s shares to continue higher ahead of September expiration looked to the September $33.33 strike where at least 2,000 now in-the-money calls were picked up at an average premium of $0.74 apiece. Call buyers make money if GMCR’s shares trade above the average breakeven price of $34.07 by September expiration day.
