ConvexBeta Investments is an independent registered investment advisor founded in 2018 and based in Hermosa Beach, California. Led by Chartered Financial Analyst Harold B. Nachtrieb, the firm builds and actively manages custom portfolios consisting of individual stocks, bonds, exchange-traded funds, mutual funds, and options for individuals, trusts, and small businesses. ConvexBeta focuses heavily on tax efficiency, seeking to minimize capital gains taxes and transaction costs while designing investment strategies tailored to each client's specific goals and risk tolerance. The firm collaborates with clients and their tax or estate planning professionals to create customized solutions. ConvexBeta uses Interactive Brokers as its custodian, which allows clients to participate in a stock yield enhancement program to earn extra income on fully paid shares. The firm offers both discretionary portfolio management—where ConvexBeta makes investment decisions on the client's behalf—and non-discretionary management, where clients approve trades in advance.
