MKM, Deutsche, and Oppenheimer's Cisco (CSCO +0.7%) checks all indicated slowing activity. MKM, which upgraded a month ago, says 60% of polled U.S. resellers reported October sales below plan. Deutsche reported seeing "below seasonal" trends for enterprise switching and routing, offset some by strength in servers, Wi-Fi, and security. Oppenheimer thinks a U.S. slowdown is a clear headwind, and will lead to below-consensus guidance when Cisco reports on Nov. 13. Some of this is likely baked in following October's earnings reports (I, II, III).
