Investment Strategy
Portolan applies fundamental analysis to evaluate investment opportunities, seeking undervalued companies with improving fundamentals. They emphasize analyzing a company's long-term future earnings power relative to its current market valuation. The firm considers elements like value, including companies undervalued relative to assets, earnings, and related metrics such as price to book, price to earnings, and price to cash flow.
The Co-Investment Fund aims for long-term capital appreciation through a concentrated portfolio of equity investments, primarily in small- to mid-capitalization companies across various industries. It pursues both "growth" and "value" investments, targeting companies with attractive businesses and favorable valuations based on fundamental analysis. The fund seeks investments that offer significant growth and capital returns due to potential catalysts or market dislocations, often investing alongside other clients in portfolio companies.
