Viavi Solutions (VIAV) is rallying as investors reprice the company’s positioning in AI-driven data-center infrastructure testing and broader next-gen network buildouts. With the next earnings date approaching (May 5, 2026), traders are leaning into the AI/data-center test equipment narrative that has been a recurring catalyst for the stock in recent months, keeping bid-side demand strong even without a single company-specific headline landing this morning.

Short positioning looks elevated enough to matter on a momentum day: Viavi had about 14.76 million shares sold short as of March 31, 2026, roughly 6.5% of the public float. When a stock with that level of short interest starts moving sharply higher, covering activity can compound the upside—especially into a catalyst window like an upcoming earnings report.

The bull case centers on accelerating demand for test, measurement, and assurance tools tied to high-speed Ethernet, network security, and data-center interconnect upgrades. Viavi has been actively showcasing AI/6G-focused testing capabilities and demos at major industry events, reinforcing the view that it sits in front of multi-year spend cycles in AI infrastructure and next-generation networks.

Near-term, traders will watch whether volume expands and whether the stock can hold gains into the May 5, 2026 earnings event, which could validate (or reset) the current optimism. Investors will also be focused on any updates around data-center momentum, margin trajectory, and integration progress from the Spirent high-speed Ethernet and security testing business acquisition.
