Sherri Scribner of Deutsche Bank is concerned with International Business Machines Corp.’s lack of organic growth and falling margins.Scribner maintained her Hold rating despite IBM’s third quarter beat.IBM’s third quarter sales of $19.2 billion and EPS of $3.29 came in modestly above Street expectations of $19.0 billion and $3.23. IBM also reiterated its full-year FY-16 EPS guidance of at least $13.50 and reiterated FCF guidance at the high end of its target range of $11-$12 billion in FY 2016.“With limited visibility on a return to sales growth or a turn in downward margins trends, we see risk/reward as balanced,” Scribner wrote in a note. $IBM, International Business Machines Corporation / 60 SourceSo Hold or?
