Watch The Hands

Yesterday after the close, the CEO of humanoid robotics company 1X posted a demo of his robot’s new tendon-driven hands—25 degrees of freedom, “nearing or surpassing human-level dexterity, strength, speed, and reliability.” It’s at about six million views as of this writing.

Introducing NEO’s 25 Degrees of Freedom, tendon-driven hands — nearing or surpassing human-level dexterity, strength, speed, and reliability. For seventy years, robotics worked around the hand problem. The humanoid bet is the reverse: it lives or dies at the fingertips.

His framing is the interesting part: for seventy years, robotics worked around the hand problem. The humanoid bet is the reverse—it lives or dies at the fingertips.

Dexterous hands are an actuator-density story. Every finger joint needs a tiny motor, a drive, a sensor, and precision control, and each step toward human-level dexterity multiplies the precision-motion content per robot. The companies that supply those components are the fingertips of the fingertips.

A Core Theme, Not A New One

Embodied AI has been one of our core themes for over a year. In May, we noted Nvidia’s CEO calling the AI factory buildout “the largest infrastructure expansion in human history”—and Nvidia carving out physical AI, including robotics, as its own.

Today the theme comes to us through our process instead of the other way around: one of today’s Market Watchers trades is a precision-motion company in that space that just hit our technical buy zone, reclaiming a key moving average in this morning’s premarket.

The Other Two Trades

Chips sold off around the world this week after Samsung’s record quarter got sold hard, then semis led Thursday’s rebound. Our other two trades today use that whipsaw the way we like to: bullish, defined-risk option structures on names in the AI-hardware supply chain, with put premium financing the upside. One is from our
Multibaggers list. Multibaggers are a handful of accounts from our Market Watchers X list with documented recent 100%+ winners.

Full details on all three trade are below.
