East Bay Investment Solutions provides ongoing investment consulting services, webinars, investment reviews, and analysis to other registered investment advisory firms rather than individual retail clients. East Bay Investment Solutions follows the principles of modern portfolio theory, emphasizing diversified portfolios, passive or evidence-based investment vehicles, and keeping costs low. The firm does not manage retail client portfolios directly or have regulatory assets under management for individuals, but rather supports the business and investment decisions of other advisory firms. East Bay Investment Solutions is led by Mario Nardone and Eric Stein, both holding the Chartered Financial Analyst designation.
