FOUNDER & GENERAL PARTNER
Nathan Maghsoudi
Nathan Maghsoudi is the Founder and General Partner of N. A. Maghsoudi & Co. and has been professionally trading in the financial markets for 10 years.
Nathan's interest in the markets was influenced by his father, Jacob Maghsoudi, an engineer and mathematician who has been an investor and trader in the financial markets for more than 40 years. Jacob's background in mathematics and engineering led him to explore systematic approaches to trading, including the development of algorithms designed for speed and execution.
Nathan took a strong interest in his father's work and began working alongside him to research, test, and develop proprietary trading systems. Their collaboration combined Jacob's decades of market experience and mathematical and engineering background with Nathan's experience as an active trader, helping form the foundation of a quantitative, research-driven investment process.
Today, Nathan leads N. A. Maghsoudi & Co. as Founder and General Partner, overseeing the firm's investment activities, quantitative research, proprietary trading systems, portfolio management, risk management, and execution.
The firm's investment philosophy continues to reflect the principles at the center of their research: rigorous analysis, systematic decision-making, technological innovation, and disciplined execution.
