VIAV is trading 4.9% down at $50.37, as its recent S&P MidCap 400 inclusion rally loses momentum amidst a broader technology sector sell-off. The company today launched the industry's first Ultra Ethernet Transport (UET) validation solution for AI fabrics, a significant new product for AI data centers. This comes after a sharp 12.23% jump on June 22, driven by its addition to the S&P MidCap 400 index, and is further pressured by the Nasdaq being down 1.35% due to renewed selling pressure in tech stocks.
