Investment thesis
Long/short equity investor focused on value, special situations, and short selling in SMID caps.
TMR Capital is a long/short equity fund focused on deep fundamental research in neglected SMID cap companies. The fund invests in value-oriented special situations including spinoffs, bankruptcies, CEO changes, M&A, and activist involvement, seeking to identify inflection points where future earnings power differs materially from the past. The fund targets 20%+ gross IRR while managing risk through a dedicated short book, underwriting at least 10% IRR from earnings growth alone to avoid value traps. Rosenthal leverages a behavioral edge from his long-term orientation and ability to withstand quarterly volatility, enabling time arbitrage in temporarily dislocated businesses in developed markets globally
Investment philosophy
Rosenthal describes a long-term, fundamentally driven approach centered on identifying inflection points where a company's future will differ meaningfully from its past. He emphasizes buying quality compounders at reasonable valuations, using deep research in neglected SMID-cap equities, and maintaining a short book for downside protection and capital efficiency.
