Research firm Broadpoint AmTech, which has been on top of the solid rally in specialty chipmakers, yesterday raised its earnings estimates and price target for Omnivision (OVTI), a chipmaker that specializes in imaging silicon for applications such as cameras in mobile phones. OVTI, a favorite of the momentum investing crowd, had huge moves from 2002-2006, but then stumbled badly in 2008. Broadpoint AmTech analyst Doug Freedman seems believes it will rally on faster-than-expected earnings growth tied to smartphone growth and other markets driving the adoption of Omnivision's imaging technology. The favorite speculation among investors now is whether it will gain entry into Apple's i-Business. It could also ride the wave of growth of cameras and imaging technology in smartphones in general.
