EXFO: Margin Improvement Could Drive The Rally, But SDN Impact A Question

From a technology perspective, EXFO has an interesting position as the leader (or 2 player) in several niches of the telecom network test-and-measurement space - it offers both portable field-test platforms that service technicians can use in the field, as well as simulators and analyzers used in the lab to simulate network traffic and optimize wireless networks prior to deployment. Although carrier capex trends do impact it, since its products are involved as much in maintenance as deployment, its business tends to be a little more stable than some of the boom-and-bust typically associated with small-cap telecom equipment suppliers.
