Unity stock holds near $21 in pre-market after forecast shock — what Wall Street watches next

Cisco Systems stock edged up roughly 0.7% to $87.35 around midday Tuesday, with investors reacting to the debut of a new AI-centric switch chip and a data center router. The company introduced the Silicon One G300, built using Taiwan Semiconductor Manufacturing Co’s 3-nanometer technology. Cisco claims the chip can route network data in microseconds, aiming to keep AI networks running smoothly even during sudden traffic spikes—and says that could deliver AI workload speed gains up to 28%. The G300 is slated to hit the market in the second half. “We focus on the total end-to-end efficiency of the network,” said Martin Lund, executive vice president of Cisco’s common hardware group, in comments to Reuters.
