Index rebalances offer a look at where secular tech trends are solidifying, and the recent shuffles for the ROBO Global Robotics and Automation Index (ROBO) and the ROBO Global Artificial Intelligence Index (THNQ) during the second quarter 2026 rebalance are no exception. These thematic benchmarks shifted weight toward the physical execution of AI and the heavy-duty semiconductor foundations required to run it.
Key Takeaways
- The THNQ index rebalance added critical semiconductor players Marvell Technology (MRVL) and Cerebras Systems (CBRS), increasing exposure to the foundational hardware layer of enterprise AI.
- The ROBO index expanded its footprint in physical automation by adding lidar and computer vision specialist Ouster (OUST) and actuation giant Schaeffler AG (SHA0 GR).
- Both indexes trimmed softer cloud and software-based business process allocations, dropping Hubspot (HUBS), Costar Group (CSGP), and Shibaura Machine Co (6104 JP).
THNQ Rebalance Strengthens AI Backbone Hardware
The THNQ index’s rebalance focused heavily on the AI backbone, a critical infrastructure bottleneck. The index added data infrastructure semiconductor pioneer Marvell Technology (MRVL) with a 2.4% weight. Additionally, it added next-generation AI hardware heavyweight Cerebras Systems Inc. (CBRS) at 1.7%.
Simultaneously, the index removed marketing platform Hubspot Inc. (HUBS) (previously 0.74% weight) and real estate data provider Costar Group Inc. (CSGP) (previously 0.62% weight).

ROBO Rebalance Expands Footprint in Physical AI
Concurrently, the ROBO index turned its focus to physical AI. Physical AI, which combines hardware with sophisticated neural networks, is empowering machinery to perceive and navigate through real-world environments instantaneously. By moving beyond rigid, pre-programmed robotics toward flexible, intelligent systems, this technology enables machines to function effectively in changing environments alongside humans.
The index added lidar sensor manufacturer Ouster Inc. (OUST) at a 1.4% weight to boost its sensing subsector, and industrial manufacturing leader Schaeffler AG (SHA) at 1.14% within the actuation subsector.
Conversely, industrial machinery veteran Shibaura Machine Co Ltd (6104) was dropped, shedding a 0.7% weight from the manufacturing and industrial automation segment.
