The only other stocks to hit 52-week highs on Monday were capital goods maker Argan ( AGX), authentication provider Collectors Universe ( CLCT) and National Research ( NRCI), a surveyor of business performance for the healthcare industry. Caribou posted an 83.3% jump in second-quarter earnings last week as revenue grew by 16.5%, and the company raised its full-year outlook. The introduction of breakfast sandwiches to its menu helped drive quarterly results. Caribou also announced a partnership with Crossmark, a sales and marketing services company, to help it expand its packaged coffee business and better compete with coffee giants like Starbucks ( SBUX), Green Mountain Coffee Roasters ( GMCR) and Dunkin' Donuts ( DNKN).
