Lunar Rock Capital is a concentrated, long-term investor in leading businesses creating the future, from artificial intelligence and software to the frontiers of healthcare, aerospace, and the global economy.
- Our goal is to generate index-beating investment returns through long-short strategies, primarily in U.S. equities.
- Investing alongside our clients — virtually all of our capital is in the fund.
- Long-term investment horizon: held for years rather than quarters and re-underwritten as the evidence arrives.
01How we invest
Every idea moves through the same repeatable, disciplined process. Deep, independent research feeds a concentrated portfolio of twenty to thirty highest-conviction positions, each sized to the strength of the insight and held primarily in highly liquid mid and large capitalization equities. Every holding is re-underwritten continuously against real-world evidence rather than defended, and risk is managed through position sizing, business quality and generally low leverage.
02What we believe
Four beliefs shape everything we own.
-
I
The pace of change is accelerating
Technological change is compounding globally and markets are slow to price it. Advances in AI and medical science are widening the gap between the companies building the future and everyone else.
-
II
Winners take most
The modern economy concentrates value in a small number of category leaders. We expect that to persist, and the next great platform shift, artificial intelligence, to amplify it.
-
III
Innovation, customer love, optionality
Ideas are replacing capital and labor as the scarcest factor of production. We look for scalable platforms customers genuinely love and where embedded optionality creates a better risk / reward than the market perceives.
-
IV
Compounding is the engine
Our theses play out over multi-year horizons. We let winners run, look to minimize realized gains, and accept stretches of underperformance as the cost of above-average long-term compounding.
03Who we are

Lunar Rock was built around the way he already invests: deep work on a small number of businesses, held with patience, and re-underwritten continuously as the evidence arrives.
