I'm long on TSMC as a "tollbooth" stock for semis because I don't have to pick winners and losers; TSMC grows regardless of which chip designers ultimately do best. I see "physical AI" is being hyped as a sort of post-LLM growth story by Jensen and others. Especially the Moonshots podcast guys whose main objective seems to be to hype up AI and profit from it. "AI Embodiment" is a term I now hear a lot about. Could the tollbooth stock for robotics be... TSM and NVDA? I own both TSM and NVDA but small amounts as a small, diversified retail investor.
Is it worth while looking for robot parts manufacturers that could become bottlenecks if robotics experiences the explosive growth many are predicting? Or is there no standard platform emerging that most robotics companies would be likely to buy from. I don't currently own any robotics pure-play stocks; the only thing close I hold would be TSLA (just a handful of shares). Would it be good to hold a robotics ETF until stronger players emerge? If so, are there any people would recommend? Preferably ones whose top 5 largest holdings aren't NVDA since I own NVDA individually and through VTI.
