Starbucks is facing some headwinds. McDonalds has improved its reputation with coffee drinkers after changing to a premium coffee. Marc Greenberg of Deutsche Bank Securities, Inc. was surprised by the consumer satisfaction results for McDonalds coffee and cut his target price on June 8th from $37 to $32 per share.
He might have been a little late.
On February 2nd, news stories reported that McDonald's coffee topped Starbucks in a Consumer Reports Taste Test.
Starbucks had been falling since late last year, coinciding with the news of the national rollout of premium coffee.
Most recently, the CFO of Starbucks indicated that it will be "very challenging" for the company to reach the upper target of its profit forecast. 6/21/07
The headwinds: new store openings slowing profit growth, milk/dairy price increases, and competition from McDonald's.
My best guess: The P/E multiple was just too high for these developments.
