Unity extended a 9-day run up 2.8% at the simulation choke while Enovix sank 12.8% after losing its CEO to Kulicke & Soffa, as semis and motion names sold off broadly.

The simulation-software choke led, bucking the risk-off tape. Unity rose +2.8% to $46.74, a ninth straight green session that has carried the stock roughly 44% off its recent base, on a second quarter that beat cleanly — revenue $546.5 million, up 24%, and adjusted EPS of $0.28 against a consensus loss of $0.09 — paired with third-quarter guidance above the Street. Simulation, training, and synthetic environments are the choke where robots learn before they touch the world: every humanoid and autonomous-mobile program needs millions of simulated hours before a physical actuator moves, and Unity's engine sits under a growing slice of that pipeline. On a day the broad market sold growth, an earnings-driven software name was the exception.

The laggard was the power-density choke, undone by governance rather than demand. Enovix fell −12.8% to $3.14 after CEO Raj Talluri resigned to run Kulicke & Soffa — a semiconductor-packaging house — leaving the board to name T.J. Rodgers executive chairman and CFO Ryan Benton interim CEO. William Blair downgraded to Market Perform and TD Cowen cut its target to $5.50. Battery power density is the choke that gates how long an actuator-heavy robot can run before it tethers to a charger, and a pre-scale silicon-anode maker losing its operator into a tape where 19-year-high yields are already crushing speculative growth is a confidence problem stacked on a macro one.

The rest of the basket sold with its inputs. The edge-AI and sensing chokes tracked the semiconductor rout — Teradyne −8.8% to $404.29, Allegro MicroSystems −11.0% to $39.39, Novanta −6.9% to $157.11, STMicro −6.3%, TE Connectivity −5.7%, Lattice −6.4%. The Japanese motion-and-actuator ADRs fell with them: Fanuc −5.4%, Yaskawa −7.7%, THK −2.9%. The rare-earth-magnets choke gave back its reshoring rally — MP Materials −3.1%, USA Rare Earth −4.0% — and platforms were mixed to soft: Tesla −0.7% to $336.87 ahead of its Optimus V3 reveal, Serve Robotics −7.1% to $4.55, Symbotic −4.5% to $40.46. Bright spots were thin — PTC +0.3%, Knightscope +0.7%.

The calendar is front-loaded. Tesla's Optimus V3 reveal and Fremont production start are targeted for the summer window, THK reports fiscal Q2 on August 31, and the ABB Robotics divestiture to SoftBank is expected to close mid-to-late 2026 — a structural shift at the platforms-and-integrators choke. Ambarella's fiscal Q2 and Nvidia both land August 26, the latter the demand signal for the robot-brains layer, with Nvidia's Isaac GR00T reference humanoid slated to ship from Unitree late in the year. The near-term tell is whether Unity's simulation-led strength marks software decoupling from the hardware selloff, or simply an earnings pop the broad derating eventually catches.
