Nov 12 (Reuters) - Shares of Green Mountain Coffee Roasters Inc fell 5 percent on Friday, after the Wall Street Journal said Starbucks Corp would come out with its own single-cup coffee maker, a move that could challenge Green Mountain's near-monopoly in the market. "Simply put, this is negative for Green Mountain Coffee Roasters in that it increases competition in single-cup coffee, where the company's Keurig brand has an approximate 80 percent share of the category," Stifel Nicolaus analyst Mark Astrachan said in a client note. Green Mountain declined to comment and Starbucks did not respond to requests for comment. Shares of Green Mountain were down 4 percent at $31.46 on Friday morning on Nasdaq. Starbucks shares were down 2 percent at $30.16.
