Wells Fargo has begun reporting on OSI Systems (OSIS) with an Overweight rating and a $170 price target. The company has a “unique position in a growing market where competitors have lost focus, with multiple avenues to increase margins,” the analyst told investors in a research note. The firm says OSI’s security segment, which accounts for 80% of its profits, has been gaining market share in recent years and expects that to continue as peers Smiths Group and Leidos (LDOS) focus on other areas. Wells sees a structural growth story in security equipment.
