OmniVision (OVTI -11.5%) falls hard after its bottom-line results and guidance disappoint the Street in spite of healthy top-line figures, thanks to inventory-driven gross margin weakness. During its earnings call, OmniVision suggested yield issues and high production costs for its high-end BSI-2 image sensors are also affecting margins. While expecting margins to remain under pressure, Needham remains positive on account of OmniVision's BSI-2 ramp and expected iPhone orders.
