Currently, one of the ETFs in the U.S. stock market with a high focus on 'humanoid robots/embodied intelligence/physical AI' is: KOID. With Unitree Robotics going public, Tesla's Optimus nearing mass production, and Jensen Huang strongly advocating for it, the humanoid robot sector is gaining more and more attention. However, the challenge with this sector lies in its complex supply chain, numerous companies in the field, and the difficulty of achieving comprehensive coverage. KOID's advantage is that this single ETF almost covers the entire humanoid robot supply chain: actuators, reducers, sensors, connectors, semiconductors, edge AI, complete machines/OEMs, rare earth magnetic materials, and more. It holds around 50 stocks, with equal-weight allocation and quarterly rebalancing. This design is crucial: KOID is not market-cap weighted but approximately equal-weighted (all holdings have similar weights). This means it’s not dominated by giants like NVIDIA, Microsoft, or Tesla, as many AI ETFs are. Instead, it allocates more weight to small- and mid-cap supply chain companies. This increases its potential for performance flexibility and also adds to its volatility. You could say KOID is one of the rare 'pure-play tools for the humanoid robot supply chain' among U.S. ETFs right now. If you're bullish on Physical AI, it's worth keeping an eye on. Compared to other robotics ETFs: KOID is for investing in the 'humanoid robot supply chain'; BOTZ/ROBO is for investing in 'mature robotics automation.' This content is sponsored by @BITstocks_CN.
