ABOUT US


Diomedes Capital is an independent equity research firm delivering fundamental, bottom-up investment analysis to institutional and retail investors. We believe rigorous, first-principles research is the foundation of sound investment decisions, and our work reflects that conviction: detailed financial models, disciplined valuation work, and clear, actionable theses built from the ground up.


Founded and led by Jordan Katz, Diomedes Capital draws on a research approach shaped by hands-on experience across both public markets and private market deal execution. This dual perspective grounds our analysis in real transaction dynamics, not just theory.


We are based in Los Angeles, California.

Investment Philosophy


At Diomedes Capital, we believe disciplined, bottom-up research is the most reliable path to identifying investment opportunities. Rather than chasing headlines or market narratives, we build our views from the ground up, starting with a company's fundamentals: its business model, competitive position, financial statements, and management quality.


Every thesis is grounded in rigorous financial modeling. We construct detailed, company-specific models to understand how a business actually generates value, then stress test our assumptions against multiple scenarios. This approach helps us separate durable competitive advantages from temporary tailwinds, and true mispricings from market noise.


We approach valuation with discipline, not dogma. No single method tells the whole story, so we triangulate across multiple valuation frameworks to build a complete picture of intrinsic value. When our estimate diverges meaningfully from the market price, and we can clearly articulate why, we have a thesis worth pursuing.


Finally, we believe good research should be independent and transparent. Our conclusions are not influenced by investment banking relationships or outside pressures. We aim to show our work, so investors can evaluate not just what we think, but why we think it.
