EZchip (EZCH -2.1%) slumps after Value Bulldog makes a short case on Seeking Alpha Pro. The author questions EZchip's low R&D and sales spending, and notes the company has often let down analysts forecasting major sales growth. Concerns are also raised about the addressable market for high-speed network processors (NPUs), competition from Broadcom's (BRCM) BCM88030 NPU, and the fact Alcatel-Lucent and Juniper are relying on their own edge router NPUs (though market leader Cisco remains a big EZchip buyer).
