Piotroski's Best: Covidien

Business: Manufactures medical devices and supplies

Piotroski Score: 9

Covidien's (COV) return on assets rose from 8.7 percent in 2010 to 9.17 percent in 2011 -- one reason the company gets Piotroski's highest ranking.

Outlook for the Company:

Bull Case: Goldman Sachs says that Covidien is continuing to gain share and that quarterly revenue should continue to rise at a rate of 3 percent to 5 percent.

Bear Case: Covidien faces increased pricing pressure and share loss to Johnson & Johnson, according to Goldman Sachs.
